Description

Description: BACKGROUND OF THE INVENTION The present invention relates to document editing, and more particularly to a document editing apparatus having a character string search function for specifying a regular expression and capable of performing character string replacement with a character attribute. About.

[Conventional technology]

A conventional character string search and replacement function in a document processing device such as a word processor is a function of replacing character strings by simply replacing a search character string with a replacement character string. or,
As shown in Japanese Patent Application Laid-Open No. 63-167960, there is a system having a function of validating the character attribute at the head of a search character string for a replacement character string.

In addition, "Practical UNIX System" (Mark.G.Sob published by Kogakusha)
As shown in ell's translation by Takeshi Yasui, 456-465), some character strings are implemented using regular expressions.

[Problems to be solved by the invention]

In the above prior art, it is possible to replace a specific character string with another character string, but for example, consider a task of searching for a part in the text that refers to a figure and changing the character attribute of the reference part. And the search function between specific strings,
When "Figure" is used as a search character string, an unrelated character string such as "Figure" as well as a figure reference point is selected by a search, resulting in a problem of poor efficiency.
Also, if you specify a search string using a regular expression,
Although it is possible to select only the figure reference position by search, in order to change the character attribute of the reference portion, exit the search mode and use the character attribute setting function to set the character attribute one by one. And set the search mode to continue the search. As described above, the conventional system is limited to the search replacement function between character strings, and there is a problem that changing the character attribute at the same time is not considered.

In addition, in the search function using a regular expression, character attributes cannot be specified as a regular expression. For example, when searching for “COMPUTER” and “computer” described in uppercase and lowercase, separate Must be described using a regular expression.

An object of the present invention is to provide a character string search function that allows a regular expression as a search character string and allows a character attribute to be specified in units of a regular expression at the time of character string search and replacement processing. Another object of the present invention is to provide a character processing device capable of simultaneously setting a character attribute.

[Means for solving the problem]

In order to achieve the above object, in the present invention, a search character string specifying means according to a regular expression, a means for specifying a character attribute of a search character string in a regular expression unit, a regular expression character search function with a character attribute, As a replacement character string designating means, a conventional character string input function and a character attribute designating function are combined, and in the replacement process, a character string found by a search is replaced with a replacement character string, and then a specification is made. This is realized by setting the specified character attribute.

[Action]

The above method consists of a simple string replacement function for the search string and the replacement string, a function to set the character attribute to the search string, a function to replace the search string with the replacement string, and a function to set the character attribute. The search replacement function is performed continuously.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a processing flow of a character string replacement method with attributes provided by the present invention, and FIG. 2 is a block diagram showing the overall configuration of a document processing apparatus to which the present invention is applied. Keyboard 100
The text data and command input from the CPU 130 are input to the register 120 through the interface circuit 110,
Is read. CPU 130 executes a control program stored in memory 140 according to the input command.
The memory 141 is a memory for storing document data. The contents of the memory 141 are stored by a “recall document” command.
The document file 150 is developed in the memory 141, and stored in the document file 150 from the memory 141 by a "store document" command. When the document data in the memory 141 is updated by the document editing function, the CPU 130 converts the document data in the editing format into display data, which are sequentially transferred to the bit map processor (BMP) 160. The BMP 160 expands the display data on the frame memory 170, and the CRT controller 180 sequentially reads the contents of the frame memory 170, and
Expand to 0.

Next, a processing flow of the character string replacement method with attributes will be described with reference to FIG. First, when the user selects the character string search function, a search definition sheet 200 shown in FIGS. 3 and 6 is displayed, and the user inputs a search target character string into the search character string input area 210 in the search definition sheet 200. To enter. (Step 10) Here, the input character string may be described as a general character string, described using a regular expression, or described by combining a plurality of regular expressions. The regular expression used in this embodiment is UNIX ("Practical UNIX System", published by Kogakusha).
5) and has the following special characters.

"＾": When started with ^, means the character string at the beginning of a paragraph (character string between line breaks or page breaks). When ＾ is the only character, it means the first character of the paragraph.

“＄”: When ending with ＄, means the character string at the end of the paragraph. ＄ alone means the last character of the paragraph.

"[...]" means any one of the characters in .... A range specification such as C ₁ -C ₂ and a selection form such as C ₁ C ₂ C ₃ may be mixed.

"[^ ...]" means a single character that does not match any of the ... A range specification such as C ₁ -C ₂ and a selection form such as C ₁ C ₂ C ₃ may be mixed.

 "C *" means zero or more repetitions of the character C.

 ". *": Means an arbitrary character string.

"￥": Characters used as special characters are treated as characters with normal meaning.

"￥ (""￥)": means the beginning and end of the regular expression when combining the regular expressions.

In this embodiment, a search character string described by a regular expression is searched from the text using FIGS. 3, 4, and 5, and
A case where the character attribute of the found character string is changed (first embodiment) will be described. 6, 7, 8, 9.
When a character string in which an attribute is added to a search character string described by a combined regular expression is searched using a figure, and the found character string is replaced with a character string and an attribute is changed in units of a regular expression ( Example 2) will be described.

First, a case where a search character string described by a regular expression is searched from the text and the character attribute of the found character string is changed will be described with reference to FIGS. 3, 4, and 5. FIG.

Using a regular expression in the search character string definition area 210 of the search definition sheet 200 shown in FIG. 3, “FIG. [1-9] [0-9]
*. [1-9] [0-9] * ". this is,
This is a regular expression that starts with "Figure" and expresses a character string composed of one or more character strings with a number other than 0 at the beginning, sandwiched by ".", And has the form "Figure XX". The number reference position is the search target.

Next, using the search character string attribute specification selection field 220 in the search definition sheet 200, whether or not to specify the attribute for the search character string is set to “Yes”. Select "None". (Step 20) In the first embodiment, "none" is selected. If "Yes" is selected, the process proceeds to the search character string attribute input (step 21), but step 21 will be described in detail in the second embodiment.

Next, using the character replacement selection field 230 in the search definition sheet 200 to determine whether or not to perform the replacement process on the search character string, “Yes” when performing the replacement, and “No” when performing only the search Is selected (step 30).

When performing substitution, a substitution character string is entered in the substitution character string input area 240 in the search definition sheet 200 (step 31).

If no replacement is performed, the process proceeds to step 50 (character string search processing).

Here, when "&" is input as a special character in the replacement character string input area 240, it means that the search character string is used as it is. That is, it is used when only the attribute is changed.

Next, the search definition sheet determines whether or not to perform character attribute replacement.
Using the replacement character string attribute designation selection field 250 in 200, "Yes" is selected when character replacement is performed, and "No" is selected when character replacement is not performed (step 40).

Here, if "&" is entered as the replacement character string and character attribute replacement "None" is selected (the search character string and the replacement character string are the same and the attribute is not changed), the processing does not make sense. Error. If an arbitrary character string (other than &) is input as the replacement character string and character attribute replacement “Yes” is selected, the attribute of the target character string is changed after performing character replacement.

When character attribute replacement “Yes” is selected in step 40,
Display the replacement character string attribute definition sheet 300 as shown in FIG.
Select the character attribute to be set (step 41).

If the character attribute replacement is "none", the process proceeds to step 50 (character string search processing).

In the present embodiment, the replacement character string attribute definition sheet 300 is composed of a typeface 310, “double-width” 320, “underline” 330, “character type” 340, and “alphabet” 350. It is possible to extend according to:

In this case, “Gothic” is selected as the typeface 310, “horizontal double” as the double-width 320, underline “Yes” with the underline 330, “No change” as the character type 340, and “No change” as the alphabet 350 And

After the selection of each attribute is completed, when the execution field 360 in the replacement character string attribute definition sheet 300 is selected, the value selected as the character attribute is set as a valid value, and the search definition sheet 20 is set.
Return to 0. When the cancel field 370 is selected, the value selected as the character attribute is invalidated, and the process returns to the search definition sheet 200.

After returning to search definition sheet 200, search definition sheet 2
When the execution field 260 in 00 is selected, the values selected in the search definition sheet 200 and the replacement character string attribute definition sheet 300 are validated, and the process proceeds to the character string search processing 50. Also,
If the cancel field 270 has been selected, the search process ends.

When the corresponding character string is found by the character string search process 50, the character string is replaced based on the information set in the search definition sheet 200 and the replacement character string attribute definition sheet 300. First, in the character replacement selection field 230 of the search definition sheet 200, the presence or absence of character replacement is determined according to the selected information (step 60). If there is substitution, it is determined whether the search character string is the same as the substitution character string (step 70). The same is that the input data to the replacement character string input area 240 in the search definition sheet 200 is "&". If the search and the replacement character string are different, a character string replacement process (step 71) is performed.

The character string replacement process replaces a character string found by a search with a replacement character string in the same manner as that performed in the conventional document processing, and includes the number of characters in the search character string and the replacement character string. Need not be the same. Also,
If the search and the replacement character string are the same, the character string replacement processing 71 is skipped.

Next, it is determined in the character attribute replacement selection field 250 of the search definition sheet 200 whether or not the attribute needs to be changed according to the selected information (step 80). If the attribute needs to be changed, a character attribute setting process (step 81) is performed. The character attribute setting process is the same as the character attribute setting function in the conventional document processing system, and sets the character attribute set on the attribute setting sheet 300 to the target character string. If the attribute does not need to be changed, the character attribute setting process 81 is skipped.

Next, when there is no replacement in step 60, or when the character string replacement processing 71 and the character attribute setting processing 81 are completed, it is selected whether or not to continue the search (step 90). When continuing, it returns to the character string search processing 50 and continues the processing,
If not, the process ends.

FIG. 5 shows an example in which search and character string replacement with attributes are actually performed according to the processing flow described above. In the original document 400 of FIG. 10A, “FIG. 2.1” 410 and “FIG. 2.2” 42
There are two search target character strings 0. On the other hand, FIG. 9B shows a case where the godskin, the double-width, and the underline attributes are added using the search definition sheet 200 and the replacement character string attribute definition sheet 300. In the document 430 after the processing is completed, “FIG. 2.1”] 440 and “FIG. 2.2” 450 have been changed to gossip, double-width, and underlined, and the arrangement has been changed accordingly.

In the above embodiment, the replacement is performed automatically in a lump, but in order to enable the user to select (replace sequentially) whether or not the replacement is possible, steps 60 and 70 in FIG. It can be easily realized by performing the user's selection process during the period.

Next, with reference to FIGS. 6, 7, 8, and 9, a character string in which an attribute is added to the search character string described by the combined regular expression is searched. On the other hand, a case in which character string replacement and attribute change are performed in units of regular expressions (second embodiment) will be described.

Using a regular expression linked to the search character string definition area 210 of the search definition sheet 200 in FIG.
\) ￥ ([0-9] * ￥) ". This is "￥
It consists of two regular expressions separated by () and “￥”, and “￥ (computer ￥)” 500 expresses the computer itself and “￥ ([0-9] * ￥)” 510 Represents a numeric string including zero. A character string having the shape of "computer numeric string" is searched.

Next, "Yes" is selected in the search character string attribute designation selection field 220 in the search definition sheet 200, and the process proceeds to search character string attribute input (step 21). Here, the search character string in the search character string input field 210 can be specified in regular expression units, and the search character string attribute can be input in the specified regular expression unit. When the range is not specified in the search character string input field 210, the search character string attribute is valid for the entire search character string.

The search character string attribute input 21 displays a search character string attribute definition sheet 600 shown in FIG. In the present embodiment, the search character string attribute definition sheet 600 is “typeface” 610, “double size” 6
20, "underline" 630, "character type" 640, and "alphabet" 650, but can be extended according to the character attributes of the system.

Here, it is assumed that “No distinction” has been selected for all items. That is, a character having a character code corresponding to the search character string is found regardless of the character attribute.

After the selection of each attribute is completed, when the execution field 660 in the search character string attribute definition sheet 600 is selected, the value selected as the character attribute is set as a valid value, and the search definition sheet
Return to 200. When the cancel field 670 is selected, the value selected as the character attribute is invalidated, and the process returns to the search definition sheet 200.

Next, using the character replacement selection field 230 in the search definition sheet 200 to determine whether or not to perform the replacement process on the search character string, “Yes” when performing the replacement, and “No” when performing only the search Select (Step 30).

When performing substitution, a substitution character string is entered in the substitution character string input area 240 in the search definition sheet 200 (step 31).

If no replacement is performed, the process proceeds to step 50 (character string search processing).

Here, when “￥ number” is entered as a special character in the replacement character string input area 240, when the search character string is expressed by combining regular expressions, the number of the regular expression from the beginning of the regular expression is determined. Expressed as a number, it becomes the replacement string corresponding to the regular expression.

In the second embodiment, the replacement character string input area 240
"Computer # 2" was entered. This changes the part corresponding to the first regular expression to "Computer" 530,
The portion corresponding to the second regular expression is “$ 2” 540, which indicates that the character string is not replaced.

Next, the search definition sheet determines whether or not to perform character attribute replacement.
Using the replacement character string attribute designation selection field 250 in 200, "Yes" is selected when character replacement is performed, and "No" is selected when character replacement is not performed (step 40).

When character attribute replacement “Yes” is selected in step 40,
Display the replacement character string attribute definition sheet 300 shown in FIG.
Select the character attribute to be set (step 41). here,
The replacement character string in the replacement character string input field 240 can be specified in regular expression units, and the replacement character string attribute can be input in the specified regular expression unit. If no range is specified in the replacement character string input field 240, the replacement character string attribute is valid for the entire replacement character string. In the second embodiment, it is assumed that the portion of "$ 2" 530 is selected and the replacement character string attribute definition sheet 300 of FIG. 8 is displayed.

In the second embodiment, the replacement character string attribute definition sheet 300
, The typeface 310 is “gothic”, the double-width 320 is “normal double”, the underline 330 is underlined “none”, the character type 340 is “full-width”, and the alphabet 3
It is assumed that "no change" is selected as 50.

After the selection of each attribute is completed, when the execution field 360 in the replacement character string attribute definition sheet 300 is selected, the value selected as the character attribute is set as a valid value, and the search definition sheet 20 is set.
Return to 0. When the cancel field 370 is selected, the value selected as the character attribute is invalidated, and the process returns to the search definition sheet 200.

After returning to search definition sheet 200, search definition sheet 2
When the execution field 260 in 00 is selected, the values selected in the search definition sheet 200, the search character string attribute definition sheet 600, and the replacement character string attribute definition sheet 300 are validated,
Proceed to character string search processing 50. Also, cancel field 27
If “0” is selected, the search process ends.

When the corresponding character string is found by the character string search process 50, the character string is replaced based on the information set in the search definition sheet 200 and the replacement character string attribute definition sheet 300. First, in the character replacement selection field 230 of the search definition sheet 200, the presence or absence of character replacement is determined according to the selected information (step 60). If there is a replacement, it is determined whether the search character string is the same as the replacement character string in regular expression units (step 70). The same is that the input data to the replacement character string input area 240 in the search definition sheet 200 is “$ number”. If the search and the replacement character string are different, a character string replacement process (step 71) is performed for each regular expression. The character string replacement processing replaces a character string found by a search with a replacement character string, similarly to the processing performed in the conventional document processing.
The number of characters in the search string and the replacement string need not be the same. If the search and the replacement character string are the same, the character string replacement processing 71 is skipped.

Next, it is determined in the character attribute replacement selection field 250 of the search definition sheet 200 whether or not the attribute needs to be changed according to the selected information (step 80). If the attribute needs to be changed, a character attribute setting process (step 81) is performed. The character attribute setting process is the same as the character attribute setting function in the conventional document processing system, and sets the character attribute selected on the attribute setting sheet 300 to the target character string. If the attribute does not need to be changed, the character attribute setting process 81 is skipped.

Next, when there is no replacement in step 60, or when the character string replacement processing 71 and the character attribute setting processing 81 are completed, it is selected whether or not to continue the search (step 90). When continuing, it returns to the character string search processing 50 and continues the processing,
If not, the process ends.

FIG. 9 shows an example in which search and character string replacement with attributes are actually performed according to the processing flow described above. In the original document 700 of FIG. 7A, “COMPUTER” 71 corresponding to “computer numeric string” is not case-sensitive.
There are three search target character strings of 0, “computer12” 720, and “computer25” 730. On the other hand, the “computer” part is replaced with “computer” using the search definition sheet 200 and the replacement character string attribute definition sheet 300, and the “numerical string” part is in gothic type, normal double, no underline, FIG. 14B shows a case where the full-width attribute is added. The document 740 after the processing is changed to “computer” 750, “computer 12” 760, and “computer 25” 770, and the arrangement is changed accordingly.

In the above embodiment, the replacement is performed automatically in a lump. However, in order to enable the user to select whether or not to perform the replacement (sequential replacement), steps 50 and 60 in FIG. It can be easily realized by performing the user's selection process during the period.

〔The invention's effect〕

According to the present invention, when the same character attribute is added to a character string conforming to a certain pattern, the character attribute setting function can be realized as a part of the search replacement processing, so that user operability and work efficiency are improved. improves.

In addition, the search character string and the replacement character string are expressed by combining regular expressions, and character attributes can be defined in units of the regular expression, thereby increasing the variety of search replacement and collectively performing various character string replacements. Work efficiency is improved.
