DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for providing information using a computer, and more particularly to a technique for easily changing or modifying provided information.

[0002]

2. Description of the Related Art Recently, with the development of computers and the spread of the Internet, electronic media such as electronic books have become widely available. After such an electronic book is once delivered to the user, in order to correct or change a part of the data, it is necessary to replace the corrected data with the delivered data, It is conceivable that the user corrects the delivered data based on the. This is because it is not easy to automatically change a part of the data stored in the electronic book at hand of the user using a computer.

[0003] Japanese Patent Application Laid-Open No. 9-54682 discloses a technique capable of changing the display of data without changing existing data.
There is a business processing data processing method of an information processing system disclosed in Japanese Patent Application Laid-Open Publication No. H10-26095.

[0004] The data processing method disclosed in this publication,
A method for processing business processing data of an information processing system that executes an application business, wherein when inputting business processing data from an external file, describing a data structure of the input data in a first record of an internal input file; A step of describing the input data in the second and subsequent records of the input file in the order of the definition of the data structure; a step of registering the memory table name in which the definition of the data structure is described with the definition of the data structure; As data on the input file, and performing registration, deletion, update, and search processing of the data corresponding to the processing request.

According to this data processing method, the definition of the data structure of the input file and the definition of the table structure are performed on the file data, so that the editing of the file definition data can be performed without changing the program code in response to the change of the data structure. Thereby, it is possible to change the contents of business process data and the like. As a result, it is possible to easily cope with a request for changing the data structure, and it is also possible to easily customize the business procedure and the display message. As a result, the function can be changed by changing the data definition file without changing the program code in response to the change in the input / output file data structure.

However, in the apparatus disclosed in the above-mentioned publication, if the input data is not input data having a definition file indicating what data is described in which part of the entire data, It is not easy to change data contents. In this case, unlike standardized business process data, which is data such as an e-book that is not standardized and contains a large amount of character data,
It is difficult to create a definition file, and it is not practical to apply it to changes in data such as electronic books.

On the other hand, since it is not easy to change a part of the data itself, if the entire data contained in the electronic book is distributed for an electronic book or the like, a medium cost and a delivery cost are required when the data is distributed by a medium. In the case of distribution using a communication line, communication costs are required. For example, if you want to distribute the latest year's statistical data for an annual report that digitized statistical data for the past several years, etc., or distribute data that corrects the statistical data of the recording year,
Since all the statistical data including the latest year's data is provided on the medium instead of providing only the latest year's statistical data, media costs and delivery costs are incurred.

[0008] For such an annual report, distribution of data for the latest year using differential data is also conceivable.
However, the number of years in which an electronic book stored by a large number of users stores data is various, and various difference data corresponding to such various electronic books is required, which is not practical. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS <Embodiment 1> The present embodiment will be described below with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are the same. Therefore, detailed description thereof will not be repeated.

FIG. 1 shows an external view of a computer which is an example of the information output device 100. Referring to FIG. 1, this computer includes a computer main body 102 having an FD (Flexible Disk) drive 106 and a CD-ROM (Compact Disc-Read Only Memory) drive 108, a monitor 104, a keyboard 110, and a mouse. 112.

FIG. 2 is a block diagram showing the configuration of the computer. As shown in FIG. 2, the computer main body 102 includes the FD driving device 106 and the CD-R described above.
In addition to the OM driving device 108, a CPU (Central Processing Unit) 120 and a memory 1
22, a fixed disk 124, and a communication interface 126 for communicating with other computers via a network. The FD driving device 106 has an FD 116
Is attached. The CD-ROM drive 108 has a CD-ROM
The ROM 118 is mounted. The information output device 100 receives main body data and user data, which will be described later, from another computer via the communication interface 126.

The information output device 100 is realized by computer hardware and software executed by the CPU 120. Generally, such software is stored in a recording medium such as the FD 116 or the CD-ROM 118 and distributed, and the FD driving device 106 or the CD-R
The data is read from the recording medium by the OM driving device 108 or the like and temporarily stored in the fixed disk 124. Further, the data is read from the fixed disk 124 to the memory 122 and
Performed by 0. The hardware itself of the computer shown in FIGS. 1 and 2 is general. Therefore, the most essential part of the present invention is FD116, CD
-Software recorded on a recording medium such as the ROM 118 and the fixed disk 124.

The memory 122 or the fixed disk 124 stores main data including a data element to be replaced and user data including replacement data. In the following description, the body data and the user data are, for example, XM
The description will be given assuming that the data element is described in an L (extensible Markup Language) format and has a data structure capable of specifying a data element.

The data structure will be described with reference to FIG. When analyzing the data structure of XML data,
It is necessary to divide the XML data into a start tag, an end tag, and a child element sandwiched between the start tag and the end tag, and to analyze the start tag into a tag name, an attribute name, and an attribute value.

The start tag is a character string part which starts with "<" and ends with ">". The end tag refers to a character string part that starts with “<//” and ends with “>”. The child element is an element between the start tag and the end tag. The child element is composed of a character string, another start tag, an end tag, and the like. If there is no child element, the start tag and the end tag can be combined into one and described as a character string that starts with “<” and ends with “/>” (in this case, an empty tag). This can be regarded as being equivalent to a start tag and an end tag being arranged side by side.

The tag name is a character string following the start tag or an empty tag "<". After the tag name,
When a character string including "=" follows, the left side of "=" is called an attribute name, and the character string surrounded by "" on the right side is called an attribute value. For example, if there is XML data “<ab =“ c ”> d </a>”, “<ab =” c ”
“>” Is a start tag, “d” is a child element, and “</a>” is an end tag. “A” in the start tag is a tag name, “b” is an attribute name, and “c” is an attribute value. In the case of an empty tag having no child element, the format is “<ab =“ c ”/>”. In the following description, when the attribute name is “b”, the attribute name is “b attribute”, and the corresponding attribute value is “b attribute”.
It is called "attribute value".

FIG. 3 shows a data structure for storing the result of analyzing the XML data. These are all stored in the memory 122. The various pointers 200 to 210 are stored at consecutive addresses in the memory 122 and manage the data of one tag. Therefore, the various pointers 200 to 210 are collectively referred to as a tag structure. Also, various pointers 200 to
210 is given a name corresponding to each function. For example, the pointer 200 is a tag name pointer, a pointer 206
Is an attribute value array pointer.

The tag name character string 224 stores character string data of the tag name. The size of the character string data changes depending on the length of the character string. The tag name pointer 200 stores the tag name character string 224 in the memory 122.
The upper address value (pointer) is stored. 20 attributes
2 stores the number of attribute name and attribute value pairs included in the tag. In FIG. 3, the number of attributes is “2”.

The attribute name array pointer 204 stores the address of the array of attribute name pointers, that is, the address value of the first attribute name pointer 212. Attribute name pointer 2
The character strings 226, 2
28 address values are stored. Attribute value array pointer 2
In 06, the address value of the array of attribute value pointers, that is, the address value of the first attribute value pointer 216 is stored. The attribute value pointers 216 and 218 store the address values of the character strings 230 and 232 of the attribute name, respectively.

The child element count 208 stores the number of child elements included in the child element surrounded by the tag. In the case of FIG. 3, the number of child elements is “3”. The child element array pointer 212 stores the address value of the array of child element pointers, that is, the address value of the first child element pointer 220. Child element pointers 220, 222, 2
24 stores the address values of the child elements 234, 236, and 244, respectively. In the case of FIG.
4 and 236 are character strings, and the child element 244 is another tag structure.

Various pointers 200 to in the tag structure
The storage size of each of the pointers 210 is fixed, and if the address value of the first tag name pointer 200 is determined, the address values of the various pointers 202 to 210 can also be calculated. Similarly, an attribute name array composed of attribute name pointers 212 and 214, an attribute value array composed of attribute value pointers 216 and 218, and a child element array composed of child element pointers 220, 222 and 224 have fixed storage sizes.
If the first address value of the array is known, the address values of other elements of the array can also be calculated.

For example, when the address value is stored in 4 bytes and the number is stored in 4 bytes, to obtain the second attribute value, first, (address value of attribute value array pointer 206) = ((tag Address value of name pointer 200) +
4 × (4-1)) and calculates the attribute value array pointer 20
6 is obtained. This attribute value array pointer 20
The value of 6 points to the address value of the attribute value pointer 216. If the value stored at a certain address is expressed by adding “*”, the address value of the first attribute value pointer 216 is (address value of the attribute value pointer 216)
= * (Address of the attribute value array pointer 206) = * (address value of the tag name pointer 200) + 4 × (4-1). Second attribute value pointer 218
Can be calculated by (address value of attribute value pointer 218) = * (address value of attribute value pointer 216) +4. Second attribute value pointer 218
Is (address value of attribute value character string 232) = (address value of attribute value pointer 218). Thereby, the character string data of the second attribute value can be accessed.

Referring to FIG. 4, a program executed in information output apparatus 100 according to the present embodiment has the following control structure for XML data analysis processing.

First, in step 100 (hereinafter, step is abbreviated as S), the CPU 120 determines the XML to be analyzed.
Determines whether the character string has ended. XML to be analyzed
When the character string ends (YES in S100), this XM
The L data analysis processing ends. On the other hand, the XML to be analyzed
If the character string has not ended (NO in S100), the process proceeds to S102.

At S102, CPU 120 reads the next character string. In S104, CPU 120 determines whether or not the start tag flag is set. If the start tag flag is set (YES in S104)
S), the process is moved to S106. On the other hand, if the start tag flag is not set (NO in S104),
The process proceeds to S108.

At S106, CPU 120 performs a start tag process. Details of the start tag processing in S106 will be described later.

In S108, CPU 120 determines whether or not the end tag flag is set. If the end tag flag is set (YES in S108)
S), the process is moved to S110. On the other hand, if the start tag flag is not set (NO in S108),
The process proceeds to S112.

At S112, CPU 120 performs the processing during the end tag. The process in the end tag is a process of acquiring the tag name in the end tag.

At S112, CPU 120 proceeds to S102
It is determined whether or not the character read in is "<". If the read character is “<” (YE at S112)
S), the process is moved to S116. If the read character is not “<” (NO in S112), the process proceeds to S114.

At S114, CPU 120 proceeds to S102
Is stored in the temporary storage area as a child element.

At S116, CPU 120 reads the next character. In S118, CPU 120 determines whether or not the character read in S116 is "/". If the read character is "/" (YE in S118)
S), the process is moved to S122. On the other hand, if the read character is not “/” (NO in S118), the process proceeds to S120.

At S120, CPU 120 sets the start tag flag to a set state and performs start tag initial processing. Details of the start tag initial processing will be described later. S1
At 22, CPU 120 sets the end tag flag to a set state.

The start tag initial process in S120 of FIG. 4 will be described. In the start tag initial processing, if there is a character string secured in the temporary storage area, it is determined as a child element, or a child element character string is additionally registered in the tag structure specified by the current tag structure pointer. The start tag flag is set, a new tag structure is secured in the memory, or the value of the tag structure is set and registered in the tag structure stack and the current tag structure pointer. That is, in the start tag initial process in S120, a child element addition process, a new tag structure registration process, and the like are performed.

The tag structure stacks 240, 2 shown in FIG.
Reference numeral 42 stores which tag of the child element is currently being processed during the XML data analysis processing. The tag structure stacks 240 and 242 in FIG. 3 store the address values of the tag structures 200 and 224, respectively. The current tag structure pointer 238 stores the address value of the most recently added tag structure stack in the tag structure stack.

A case where a child element is added in the start tag initial processing in S120 will be described. The number of child elements of the tag structure pointed to by the current tag structure pointer 238 is increased by one, and a child element pointer is added to the child element pointer array. If the child element pointer is the first child element pointer, the address value of the child element pointer is changed to the child element pointer. Set to an array pointer,
The child element pointer sets the address value of the child element character string.

FIG. 6 shows an example of body data, FIG. 7 shows an example of user data, FIG. 8 shows a data structure obtained by analyzing the body data shown in FIG. 6, and FIG. 9 shows a data structure obtained by analyzing the user data shown in FIG. Are respectively shown.

If no value is set in 38, the tag structure is determined to be the first tag structure, the address value of the new tag structure is set in the tag structure stack 240, and the address value of the tag structure stack 240 is set. Is set to the current structure pointer 238. If a value has already been set in the current structure pointer 238, it is registered as a child element of the tag structure (hereinafter referred to as a parent tag structure). Specifically, the number of child elements of the parent tag structure is increased by "1", a child element pointer is added to the child element character string, and an address value of a new tag structure is set.

With reference to the body data of FIG. 6 and the data structure of FIG. 8, the start tag initial processing in S120 other than the above will be described.

At S136, CPU 120 determines whether or not the character to be analyzed is ">". If the character to be analyzed is ">" (YES in S136), the process proceeds to S150. On the other hand, if the character to be analyzed is not “>” (NO in S136), the process proceeds to S152.

In S138, CPU 120 determines in S130
When the character to be analyzed is a space, it is determined whether the tag name processing flag is set. This determination is made based on, for example, whether or not the tag name pointer is “0”. "0" for the address value of the tag name pointer
When the tag name is included, the tag name has not yet been obtained, so the tag name processing flag is determined to be in the reset state. If the address value of the tag name pointer contains a value other than "0", it is determined that the tag name has already been acquired, and the tag name processing flag is determined to be in the set state. If the tag name processing flag is set (YE at S138)
S), the process is moved to S140. On the other hand, when the tag name processing flag is in the reset state (NO in S138),
The process proceeds to S142.

In S140, CPU 120 performs tag name end processing, and ends start tag processing. The end processing of the tag name processing is to determine the character string secured in the temporary area as the tag name character string, set the address value of the tag name character string in the tag name pointer, and reset the tag name processing flag It is to be. In FIG. 6, “replac
e ”is stored in the tag name character string 344, and the tag name pointer 3
26, the address value of the tag name character string 344 is set.

In S142, CPU 120 performs an attribute value end process, and ends the start tag process. In the attribute value end processing, the character string secured in the temporary area is determined as the attribute value character string, and one attribute value pointer is added to the attribute value pointer array. If it is the first attribute value, the address value of the first attribute value pointer is set in the attribute value array pointer. Also, "" included in the character string is deleted.

Referring to FIG. 6, in the process in S 142, “year” is set in attribute value character string 348, the first attribute value pointer array is reserved in attribute value pointer 340, and the attribute value The address value of the attribute value pointer 340 is set, and the attribute value pointer 34
The address value of the attribute value character string 348 is set to 0.

In S144, when the character string to be analyzed is "=", CPU 120 performs an attribute name end process and ends the start tag process. In the attribute name end processing, the character string secured in the temporary area is determined as the attribute name character string, and 1 is added to the number of attributes. One of the attribute name pointers is added to the attribute name pointer array, and if it is the first attribute name, the address value of the first attribute name pointer is set in the attribute name array pointer. In FIG. 6, "va
r ”is set in the attribute name character string 346, and the attribute number storage unit 3
28, “1” is set, the attribute name pointer 338 is secured as the first attribute name pointer array, the address value of the attribute name pointer 338 is set in the attribute name array pointer 330,
The address value of the attribute name character string 346 is set in the attribute name pointer 338.

At S146, CPU 120 resets the start tag flag when the character to be analyzed is "/". At S148, CPU 120 performs end tag processing. The end tag process is a process of erasing the tag structure stack pointed to by the current tag structure pointer and returning one current tag structure pointer. In FIG. 6, the tag structure 242 is deleted, and the address value of the tag structure 240 is set in the current tag structure pointer 238.

At S150, when the character to be analyzed is ">", CPU 120 resets the start tag flag. Thereafter, the process ends.

At S152, CPU 120 performs a character addition process when the character to be analyzed is not a space, any of "=", "/" and ">". The character addition processing is to add a character to be analyzed to the temporary storage area.

By analyzing the XML data in this manner, the body data shown in FIG. 6 is represented by the data structure shown in FIG. 8, and the user data shown in FIG. 7 is represented by the data structure shown in FIG. Can be. In the following description, a case where a part of the main data is corrected or changed using the user data represented by such a data structure will be described.

Referring to FIG. 10, a program executed by information output apparatus 100 has the following control structure for information output processing. At S200, CPU 120
Reads the number N1 of child elements in the body data. When the body data shown in FIG. 6 is the data structure shown in FIG. 8,
The value stored in the number of child elements 308 is read. In the case shown in FIG. 8, the child element number N1 is “4”.

At S202, CPU 120 initializes a variable HCCY representing the current child element number of the main body data (HCCY = 1).

At S204, CPU 120 determines whether there is any child element before the processing. This determination is made by comparing the variable HCCY representing the current child element number of the body data with the number N1 of child elements of the body data. If the number of child elements before processing does not exist, that is,
If HCCY> N1 (YES in S204), this information output process ends. On the other hand, if there is a child element before the process, that is, if HCCY ≦ N1 (NO in S204), the process proceeds to S206.

At S206, CPU 120 determines that the HCCY
Get the child element pointer of the child element number. For example, when the data structure is shown in FIG. 8 and the variable HCCY indicating the current child element number is “1”,
The value is obtained from the child element pointer 312. If the variable HCCY representing the current child element number is "2", the value of the child element pointer 314 is obtained.

At S208, CPU 120 proceeds to S206.
It is determined whether or not the child element pointer acquired in is a replace tag. If it is a replace tag (YES in S208), the process proceeds to S210. On the other hand, if it is not a replace tag (S20
8 is NO), the process proceeds to S214. Note that re
In order to determine whether or not the tag is a place tag, first, it is determined whether or not the one designated by the child element pointer is a child element character string or a tag structure. This is performed by detecting the tag name character string indicated by the pointer and determining whether the tag name character string matches "replace". In the case shown in FIG. 6, when the current child element number is "1", the child element pointer 312 indicates the tag structure 326, and the tag name character string 344 is obtained from the tag name character string pointer 326. obtain. Since the character string in this case is “replace”, it is determined that the character string is a replace tag.

At S210, CPU 120 sets repl
The attribute value of the attribute name “var” in the ace tag is acquired.
The attribute value of the attribute name “var” in the replace tag is called “variable name”. In order to obtain the attribute value of the attribute name “var”, the attribute name pointer in the attribute name pointer array is searched in order, and the attribute name character string “var” is detected. If it can be detected, the corresponding attribute value pointer may be obtained from the attribute value pointer array, and the attribute value character string may be obtained. Since the order of the attribute name pointer array and the attribute value pointer array correspond, for example, the attribute value pointer corresponding to the second attribute name pointer is the second attribute value pointer array. In FIG. 6, for example, when the current child element number is “1”, the attribute name pointed to by the attribute name pointer 338 is “var”. The character string “year” in column 348 is obtained as the variable name.

At S212, CPU 120 performs a replacement process. The details of the replacement process will be described later.

At S214, CPU 120 proceeds to S206.
If the child element pointer acquired in is not a replace tag, the character string of the child element is added to the display character string.

After the processing in S212 and S214, in S216, CPU 120 sets the variable HCCY representing the current child element number of the main body data to HC
The calculation of CY = HCCY + 1 is performed, and thereafter, the processing is S
Returned to 204.

Referring to FIG. 11, the replacement process in S212 of FIG. 10 will be described. At S220, the CPU
120 reads the number N2 of child elements of the user data. This is performed by reading a value stored in the child element number 408 of the userdata tag of the user data.

At S222, a variable UCCY representing the current child element number of the user data is initialized (UCCY =
1) Yes.

At S224, CPU 120 determines whether or not there is no child element before processing. This determination is made by comparing a variable UCCY representing the current child element number of the user data with the number N2 of child elements of the user data. When there is no child element before processing, that is, when UCCY> N2 (YE at S224)
S), the process is moved to S246. On the other hand, if there is a child element before the process, that is, if UCCY ≦ N2 (NO in S224), the process proceeds to S226.

At S226, CPU 120 determines that UCCY
Get the child element pointer of the child element number.

At S228, CPU 120 determines at S226
It is determined whether or not the child element represented by the child element pointer acquired in is a var tag.

At S230, CPU 120 performs a var tag initializing process. In this var tag initial processing, v
The number of attributes NV of the ar tag is read. S2
At 32, CPU 120 initializes variable CATT representing the current attribute number (CATT = 1).

At S234, CPU 120 determines at S232
After the processing in, it is determined whether there is no attribute name before the processing in the var tag. This determination is made by comparing the attribute number NV of the var tag with the current attribute number CATT. If there is no attribute name before the process, that is, if CATT> NV (YES in S234), the process returns to S248. On the other hand, when the attribute name before the process exists, that is, when CATT ≦ NV (NO in S234), the process proceeds to S236.

At S248, CPU 120 determines at S228
If it is determined in step S234 that the attribute name is not a var tag, and if it is determined in step S234 that there is no attribute name before processing, the calculation UCCY = UCCY + 1 is performed on the variable UCCY representing the current child element number.

At S236, CPU 120 determines whether or not CATT
Get the attribute name pointer of the current attribute number.

In S238, CPU 120 determines in S236
It is determined whether or not the attribute acquired in is the name attribute. That is, it is determined whether or not the attribute name character string is “name”, and if the attribute is “name” (S238)
Is YES), the process proceeds to S240. On the other hand, if the attribute is not the name attribute (NO in S238),
The process proceeds to S250.

At S240, CPU 120 determines that the name
Get attribute value. The acquisition of the name attribute value is performed by obtaining the address value to the attribute value character string from the attribute value pointer of the variable CATT representing the current attribute number of the attribute value pointer array.

At S242, CPU 120 proceeds to S240
It is determined whether or not the name attribute value acquired in step is the same as the variable name of the main routine. If the acquired name attribute value is the same as the variable name of the main routine (S242
Is YES), the process proceeds to S244. On the other hand, if the acquired name attribute is different from the variable name of the main routine (NO in S242), the process proceeds to S250.

At S244, CPU 120 adds the value of the value attribute of the var tag of the user data to the display character string.

In S246, if there is no child element before the processing, CPU 120 replaces the main data.
Add the tag child element string to the display string.

The operation of the information output device 100 according to the present embodiment based on the above structure and flowchart will be described. In the following description, different display character strings are output when information is output using only the main data shown in FIG. 6 and when information is output using the main data shown in FIG. 6 and the user data shown in FIG. An operation capable of outputting can be realized. That is, by using the user data, a part of the character string of the main body data is replaced by the user data.

As shown in FIG. 6, the body data has its replacement part described using XML tags. That is, the character string sandwiched between the start tag and the end tag of the replace tag is the character string of the replacement part. relac
As the value of the var attribute of the e tag, “year”, “nu”
m ”is described. As shown in FIG. 7, in the user data, a character string to be replaced is described using an XML tag. As the value of the name attribute of the var tag, "yea
r ”and“ num ”are“ 1 ”as the value of the value attribute.
999 "and" 300 "are described. In the following description, the value specified by the var attribute is referred to as “r”.
The variable specified in the "place tag" and the value specified by the name attribute are replaced with the "variable name in the var tag" and the value
The value specified by the attribute is referred to as “variable value of var tag”.

When the display is performed without using the user data by the processing according to the above-described flowchart, the replacement does not occur. Therefore, the character strings "1998" and "200" of the child element of the replace tag are used as they are as the display character strings. Then, "200 users in 1998" is displayed on the monitor 104 of the information output device 100. On the other hand, when a part of the body data is replaced using the user data, the variable values "1999" and "300" of the var tag of the user data having the same variable name as the variable name of the replace tag of the body data are displayed. It is used as a character string, and is displayed on the monitor 104 of the information output device 100 as "300 users in 1999."

As described above, the description indicating the part to be replaced with the body data is performed, the description indicating the content to be replaced with the user data is performed, and the body data and the user data are output together. By causing the information output device 100 to output contents different from the case where the information is displayed,
It can be displayed so that people can recognize it. Thus, the display result can be changed only by changing the content of the user data without changing the main body data. For example, when applied to e-book content data, when the contents such as statistical data are to be updated to the latest information, conventionally, the main data itself had to be corrected. Can be replaced. As a result, redistribution of the corrected data generally involves communication costs, etc., because the data volume of the main body data is large, but when replacing the contents using user data, only the data of the changed part is distributed. Therefore, the data amount can be small, and the communication cost can be kept low.

Even when the main body data is on a non-rewritable medium such as a CD-ROM or on a network and has no rewriting means or write authority, the main body data can be rewritten. The display content of the main data can be changed using the main data and the user data.

Further, even when the main data is encrypted, there is an advantage that it is unlikely to cause a security problem by changing the display at the time of display using the user data.

As described above, the information output device according to the present embodiment replaces the element specified by the data structure of the body data with the user data without changing the body data stored in advance. Thus, the main body data can be output so that a person can recognize it. As a result, it is possible to provide an information output device that can easily change or correct digitized data.

<Embodiment 2> An information output apparatus 100 according to the present embodiment replaces a part of the main data with user data by describing the range designation of the replacement part in the user data. It is. Note that the other hardware configuration and the processing flow are the same as those in the above-described embodiment, and thus detailed description thereof will not be repeated.

[0109] In the present embodiment, portions different from the above-described embodiment will be described.

FIG. 12 shows main body data and FIG. 13 shows user data used in the present embodiment. FIG.
As shown in (1), the body data does not have a data structure for specifying the element to be replaced. On the other hand, as shown in FIG.
The user data is in the replace tag,
It has a value of the t attribute and a value of the end attribute.

Referring to FIG. 14, the program executed by information output device 100 has the following control structure for the replacement process.

At S300, CPU 120 initializes a variable KW representing a character number (KW = 1).

At S302, CPU 120 determines whether or not there is a main body character string before processing. If there is a main body character string before processing (YES in S302), the processing proceeds to S3
04. On the other hand, if there is no main body character string before the processing (NO in S302), this replacement processing ends.

At S304, CPU 120 obtains the KW-th main body character string. At S306, CPU 120
Determines whether the character string output in S304 falls within the range specification of the replace tag. If the acquired character string falls within the range specification of the replace tag (S
(YES at 304), the process proceeds to S308. On the other hand, if the obtained character does not fit in the range specification of the replace tag (NO in S304), the process proceeds to S31.
Moved to 4.

In S308, CPU 120 sets repl
Add the child element of the ace tag to the display character string.

At S310, CPU 120 adds the main body character to the display character string. At S312, CPU 120
Skips the KW-th body character string.

After the processing in S310 and S312, the processing in S31
At 4, CPU 120 determines that KW =
Perform KW + 1 operation. After the process in S314, the process returns to S302.

The operation of the information output device 100 according to the present embodiment based on the above structure and flowchart will be described.

In the case where user data is not used, FIG.
Is displayed on the monitor 104 of the information output device 100, "200 users in 1998." On the other hand, when the user data shown in FIG. 13 is used, the first to fourth characters described as the range specification of the replace tag of the user data are changed to “1999”, 11
The thirteenth to thirteenth characters are each replaced with “300”. As a result, the character string of the body data shown in FIG. 12 is replaced, and "300 users are used in 1999."
Is displayed on the monitor 104 of the information output device 100.

As described above, also in the information output apparatus according to the present embodiment, the specific element specified by the data structure of the main data can be obtained only by changing the user data without changing the main data. Can be replaced by replacement data of the user data.

<Third Embodiment> The information output device 100 according to the present embodiment does not display the replaced character string or data as it is, but interprets the replaced main body data again and displays it. An information output device capable of Note that the other hardware configuration and the processing flow are the same as those in the above-described embodiment, and thus detailed description thereof will not be repeated.

Hereinafter, portions of the present embodiment that are different from the above-described embodiment will be described.

FIG. 15 shows main body data and FIG. 16 shows user data used in the information output device 100 according to the present embodiment. As shown in FIG. 15 and FIG.
Then, when expressing “<” and “>” as characters instead of tags, “<” is “&lt;” and “>” is “& g”.
t; ". Conversely, when interpreting XML, “&lt;” is replaced with “<” and “& g
"t;" has a convention of being converted to the character ">".

If these are output only with the main data, the display character string is as shown in FIG. FIG. 18 shows a further output using the user data. The character string described in the HTML data shown in FIG. 18 is again interpreted by the WWW browser, so that the file specified by the img tag is changed to image data. For this reason, when outputting text data in the information output device, the displayed image file is replaced depending on whether or not user data is used.

As described above, by reinterpreting the replaced main body data, it is possible to perform not only simple data replacement but also more complicated operation (displayed image replacement) with user data. Can be.

<Embodiment 4> The information output device 100 according to the present embodiment is similar to the repl
An information output device that replaces part of the main body data with user data using a show tag, an erase tag, or the like instead of the ace tag. Note that the other hardware configuration and the processing flow are the same as those in the above-described embodiment, and thus detailed description thereof will not be repeated.

[0127] Hereinafter, portions of the present embodiment that are different from the above-described embodiment will be described.

Referring to FIG. 19, the program executed by information output device 100 has the following control structure for the replacement process.

In S410, CPU 120 determines in S408
It is determined whether or not the child element acquired in is a show tag. If the child element is a show tag (S410
YES), the process is moved to S412. On the other hand, if the child element is not a show tag (NO in S410),
The process moves to S416.

At S412, CPU 120 determines whether or not
The address of the tag structure of the tag is registered in the display show tag list. The information registered in the display show tag list is displayed on the monitor 104 of the information output device 100.

In S414, CPU 120 determines in S406
If there is no child element before processing, user data processing is performed. Details of the user data processing will be described later.

At S416, if the child element is not a show tag and if the address of the tag structure of the show tag is registered in the display show tag list, CPU 120 determines the variable HCCY representing the current child element number. , HCCY = HCCY + 1.

With reference to FIG. 20, the user data processing in S414 of FIG. 19 will be described. At S420, the CP
U120 determines whether or not there is user data. If there is user data (YES in S420), the process proceeds to S422. On the other hand, if there is no user data (NO in S420), the process proceeds to S440.

At S422, CPU 120 reads the number N4 of child elements of the user data. In S424, the CPU
120 initializes a variable UCCY representing the current child element number of the user data (UCCY = 1).

At S426, CPU 120 determines whether or not there is no child element before processing. This determination is made by comparing the variable UCCY representing the current child element number of the user data with the number N4 of child elements of the user data. If there is no child element before processing, that is, if UCCY> N4 (Y in S426)
ES), the process proceeds to S440. On the other hand, if there is a child element before processing, that is, if UCCY ≦ N4 (NO in S426), the process proceeds to S428.

At S428, CPU 120 sets UCCY
Get the child element pointer of the child element number.

At S430, CPU 120 determines at S428
It is determined whether or not the child element acquired in is a show tag. If the acquired child element is a show tag (YES in S430), the process proceeds to S432.
On the other hand, if the acquired child element is not a show tag (NO in S430), the process proceeds to S434.

At S432, CPU 120 determines whether or not
The address of the tag structure of the tag is registered in the display show tag list.

At S434, CPU 120 determines at S428
It is determined whether or not the child element acquired in is an erase tag. If the acquired child element is an erase tag (YES in S434), the process proceeds to S436. On the other hand, if it is not an erase tag (S434
NO), the process proceeds to S438.

At S438, CPU 120 calculates UCCY = UCCY + 1 for variable UCCY representing the current child element number of the user data. Thereafter, the process proceeds to S426.

At S436, CPU 120 sets eras

At S440, CPU 120 sets display sh
The image file is copied to the display bitmap data area based on the contents of the ow tag list.

The operation of the information output device 100 according to the present embodiment based on the above structure and flowchart will be described.

[Whole Image Replacement Operation] For example, if the data as shown in FIG. 21 exists as the main body data and there is no user data, the “graph.jpg” file is output according to the above-mentioned flowchart. This is displayed on the monitor 104 of the device 100, and a graph 500 as shown in FIG. 32 is displayed. When the notation of the x-axis and the notation of the y-axis in FIG. 32 are interchanged, the repl is obtained by using the user data shown in FIG.
The "newgraph.jpg" file can be displayed using the ace tag, and a new graph is displayed as shown in FIG. As a result, the entire image data is replaced, so that the correct coordinate axes are displayed.

[Partial Image Replacement Operation] When the user data shown in FIG. 23 is used for the main data shown in FIG. 21, "graph.j" is described as described in the above-mentioned flowchart.
pg "file," y.jpg "file and" x.jp "
g ”file is registered in the display show tag list,
These three files are displayed on the monitor 104. That is, the main body data (FIG. 21) is output, and "grap
h. In addition to copying the “jpg” file to the display bitmap area, the “y.jpg” file is overwritten, and the “x.jpg” file is overwritten.
Note that sx and sy are coordinate positions where image data is displayed,
src indicates an image file name. As a result, FIG.
The graph shown in FIG. 33 is replaced with a graph shown in FIG. That is, by outputting the body data using the user data (FIG. 23), the “y.jpg” file is displayed as the y-axis display area 514, and the “x.jpg” file is displayed.
g "file is displayed as the x-axis display area 512.
As a result, the y-axis display area 514 and the x-axis display area 512 of the portion to be corrected in the graph image 510 are overwritten using the user data. Note that the dotted frame in FIG. 33 is displayed for explanation, and actually the monitor 1
04 is not displayed.

[Element erasing operation] A case will be described in which the main data is described by adding an id attribute to a show tag as shown in FIG. 24, and the user data is described as shown in FIG.

FIG. 34 shows a case where the main body data shown in FIG. 24 is displayed on the monitor 104 of the information output device 100.
This display is composed of two image files, a “book.jpg” file indicating a display range 550 of “book:” and a “bookj.jpg” indicating a display range 552 of “book”.

As described above with reference to the flowchart, when only the main body data shown in FIG. 24 is output, the display show tag list includes “book.jp”.
g ”file and“ bookj.jpg ”file
Two show tags are registered in the display show tag list. Thus, information as shown in FIG. 34 is displayed on the monitor 104 of the information output device 100.

When the body data is output using the user data shown in FIG. 25, the show tag having the id attribute value of “002”, ie, “book” is output by the erase tag.
j. The “show” tag of the “jpg” file will be deleted from the displayed show tag list. Therefore, only the show tag of the “book.jpg” file is included in the display show tag list, and the “show” tag shown in FIG.
ok: ”only in the display area 554.

As described above, by displaying the main data and the user data, a part of the data can be deleted.

The case where the main data is described as shown in FIG. 26 and the user data is described as shown in FIG. 27 will be described.

When only the main body data is displayed by the information output device 100 in accordance with the above-described flowchart, as shown in FIG. 36, a “bookej.jpg” file is used.
An area 556 is displayed, and “mas” is displayed in the area 558.
k. The "jpg" file is overwritten. For this reason,
The “book” portion of “book: book” in the area 556 is “ma”
sk. The “book” part is invisible as a result of being overwritten by the image of the “jpg” file. When the user data shown in FIG. 27 is output together, the area 550 of the blank image portion in FIG. 36 is not displayed, and the “book” portion is displayed as shown in FIG.

By appropriately combining the body data and the user data, for example, a mask image to be displayed so as to be superimposed on a word to be remembered can be displayed or hidden by using the user data. .

[Replace Operation] The main data is as shown in FIG.
8 and the case where the user data is described as shown in FIG. 29 will be described.

When the main body data is displayed on the monitor 104 using the user data, the twelfth character "book" of the main body data is replaced with "space" (blank character), and "bo" is displayed.
ok: space ", and the" book "portion becomes invisible on the display. If you use a character such as “□” instead of “space” (blank character), you will be able to recognize that there is something hidden underneath.

Further, instead of changing the character string data itself of the body data, the display attributes thereof can be changed. For example, there is data as shown in FIG. 30 as user data, and text_attribute is used.
When interpreting the tag, the character drawing color of the text character string in the range specified by the start attribute and the end attribute is changed as specified by the fgcolor attribute. As shown in FIGS. 28 and 30, the character drawing color of the “book” portion in the text character string of the main body data is set to “whi”
te ”(white). If normal text is drawn with a white background and a black character drawing color, this user data is output and displayed, so that the character string of the "book" can be made invisible. To realize this, it is necessary to save not only the display character string but also the character drawing color and the character background drawing color for each character.

Further, user data can be described as shown in FIG. When the user data is created as shown in FIG. 31, when the text_attribute tag is interpreted, the background drawing color of the text character string is set to bg.
Change to the color specified by the color attribute. In the text string of the body data (FIG. 28), the character drawing color of the "book" portion is set to "black" (black), and the background drawing color is set to "b".

FIG. 50 is a view for explaining the data structure of data used in the present embodiment. In the following description, this data structure will be referred to as a variable object. The tag structures 600 to 612 in FIG.
They are arranged and secured in 22 continuous areas, and are each represented by a fixed number of bytes. Storage section 600 for the number of variables
Is set to the number of variables currently being managed. In the case of FIG. 50, since three variables are managed, “3” is set in the storage unit 600 of the number of variables. The character string data 614 is a character string of the name of the first variable, and this address value is stored in the variable name address pointer 602. The character string data 616 is a character string of the value of the first variable, and this address value is stored in the variable name address pointer 604. Hereinafter, description will be made assuming that the name of the second variable and the value of the variable are also stored.

Var of the child element shown in S580 of FIG. 41
In the tag processing, if the variable specified by the name attribute does not exist, the variable name and the value area are secured and the value is set. Further, an area for a variable name address pointer and a variable value address pointer is added, the value of the number of variables storage unit 600 is incremented by 1, and the variable name address pointer is set to the address value of the variable name character string, Set the address value of the variable value character string to the address pointer. Whether a variable with a certain name exists can be obtained by obtaining the variable name via a variable name address pointer and confirming whether the variable name is the same. If the variable already exists, you only need to set the value of the variable. In addition,
In the first embodiment, processing is performed by directly looking at the tag structure of the user data without using such a variable object. First, the user data is analyzed to create a variable object. You can also refer to a variable object and process it to use the value of that variable. Although the method of creating a variable object using the var tag has been described here, it is also possible for the system to have the variable object from the beginning. For example, a function (such as an environment variable in a computer) representing the state of the device at that time can be considered.

The operation of the information output device 100 according to the present embodiment based on the above structure and flowchart will be described.

[0200] For example, the operation of information output apparatus 100 when described as main data as shown in FIG. 42 and as user data as shown in FIG. 43 will be described.

First, when the main body data is output, "boo"
kej. jpg ”file's show tag is displayed sh
Join the ow tag list. Next, by outputting the user data and processing the var tag, the variable name “mask”
Variable object is created. Next, switch
The tag is processed and the current mask variable value is "on"
Therefore, <show id = “002” sx = ”
50 "sy =" 0 "src =" mask. jpg "/
> Is evaluated and added to the display show tag list.

Since no input has occurred from the mouse 112 or the like, no processing is performed even if the click tag is evaluated. Finally, two files in the display show tag list are displayed, and information as shown in FIG. 36 is displayed.

Next, a case where the user clicks the area 558 in FIG. 36 using the mouse 112 or the like will be described. The click is recorded, and the body data and the user data are reevaluated. The evaluation result of the body data does not change. The var tag of the user data is processed, but since the mask variable object already exists, the init_value attribute is ignored and nothing is processed. Next, the switch tag is processed, but the evaluation result remains unchanged. At this point, the display show
Two show tags are registered in the tag list.
Next, when the click tag is evaluated, it is recorded that a click has occurred, and if the position of the clicked coordinate falls within the specified range, the child element is processed. The switch tag of the child element is processed,
Since the value of the mask variable is “on”, <var n
ame = "mask", value = "off"/>. The value of the mask variable is set to "off",
The evaluation of the body data and the user data is performed again.

The evaluation result of the main data remains unchanged. The user data processes the var tag, but since the mask variable object already exists, the init_value attribute is ignored and nothing is processed. Next, switch
The tag is processed, and the value of the current mask variable is "off"
However, since no corresponding case tag exists, nothing is processed. Since no click has occurred, cl
Nothing is processed when the ic tag is evaluated. Finally, one file in the displayed show tag list is displayed, and the display is as shown in FIG. That is, the mask portion disappears, and the display of “book” below becomes visible.

In this state, when stopping the information output device 100, there is a case where it is desired to keep the current value of the variable at the next startup. This can be realized by rewriting the user data.
Specifically, for example, the value of the current mask variable is “o
ff ”, the first var tag is replaced with <va
r name = “mask” init_value
= “Off” />. Thus, "off" can be set at the time of first reading.

Here, it is assumed that the user clicks again on area 558 shown in FIG. The click is recorded as a record, and the main data and the user data are reevaluated. The evaluation result of the body data does not change. On the other hand, the user data processes the var tag, but since a mask variable object already exists, the init_value attribute is ignored and nothing is processed. Next, the switch tag is processed, and the evaluation result remains unchanged. At this point, two show tags are registered in the displayed show tag list. Next, when the click tag is evaluated, it is recorded that the click has occurred, and it is within the range. Therefore, the child element is processed. Since the switch tag of the child element is processed and the value of the mask variable is “off”, <
var name = "mask" value = "on"
// is processed. The value of the mask variable is set to “on”, and the main data and the user data are reevaluated again.

The evaluation result of the main data remains unchanged. The user data processes the var tag, but since a mask variable object already exists, init_val
The ue attribute is ignored and nothing is processed. Next, swi
The tch tag is processed, and the value of the current mask variable is “o”.
n ”, <show id =“ 002 ”sx
= “50” sy = “0” src = “mask.jp”
g ">> is evaluated and added to the display show tag list. Since no click has occurred, nothing is processed even if the click tag is evaluated. Finally, two files in the display show tag list are displayed. Is displayed, and FIG.
The state shown in FIG. That is, by clicking, the mask appears again.

As described above, by clicking the mask portion, display / non-display is switched like a toggle switch, and the state can be recorded as a user parameter. Can be restored. Such a function can be used, for example, when a word or the like is to be stored in a learning reference book or the like.

Next, as shown in FIG.
The operation of the information output device 100 when the user data is described as shown in FIG. 45 will be described.

In the case of the show tag shown in FIG. 45, a predetermined operation is not realized by switching between display and non-display of the mask image.
By replacing the “book” portion with “□” and displaying the same, the same operation as that of displaying the mask image can be realized.

Further, when the main data is described as shown in FIG. 46 and the user data is described as shown in FIG. 47, the same operation can be realized by using text_attribute. In the case of the replace tag, the “book” part is replaced with “□” and displayed.
As shown in FIG. 47, in this user data, te
In the case of the xt_attribute tag, the same effect as the mask display can be realized by setting both the character background color and the character drawing color of “book” to black.

The operation of the information output apparatus 100 when the main data is described as shown in FIG. 48 and the user data is described as shown in FIG. 49 will be described.

Referring to FIGS. 48 and 49, variable di
The value of “reaction” is not specified by the body data or user data, but is held by the system. For example, in Japanese, there are vertical writing and horizontal writing, but when performing vertical writing, the value of the variable direction is set to “vretical”, and when performing horizontal writing, the value of the variable direction is set to “horior”.
It is assumed that "zontal" is set. When performing horizontal writing using the main body data of FIG. 48 and the user data of FIG. 49, the value of the variable direction is “hori”.
Nothing is processed even if the user data is analyzed. The display character string remains the same as the main body data, and the "upper figure is a figure explaining a series of processing."
Becomes

On the other hand, when displaying vertically, the variable d
Since the value of “direction” is “vretical”, the replacement of the character string by the replace tag occurs, and the display character string is “the figure on the right is a figure explaining a series of processes”. In vertical writing, the lines go from right to left, so if you want to indicate something that came before,
In the case of vertical writing, it will be replaced with "right".

As described above, by performing the distribution process using the variable value using the switch tag, the display can be changed according to the state.

As described above, also in the information output device according to the present embodiment, it is possible to replace and display some elements of the body data using the user data without changing the body data. .

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
