Abstract

PURPOSE:To improve the operability and the work efficiency by realizing a character attribute setting function as a part of a search substitution processing. CONSTITUTION:The system is provided with a simple character-string substitution function of a search character-string and a substitute charcter-string, a function for executing character attribute setting to the search character-string, and a function for substituting the substitute character-string for zero of a search character, and also, setting a character attribute. Also, the system is allowed to have both of a character-string input function and a character attribute designating function as a substitute character-string designating means, and at the time of executing the substitution processing, the substitute character- string is substituted for the character-string detected by the search, and thereafter, a designated character stribute is set. In such a way, the character-string substitution can be executed together with the character attribute, and the work efficiency is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to document editing, and in particular to a document editing device that has a regular expression specified character string search function and can perform character string replacement with character attributes. Regarding.

[Conventional technology]

The search and replacement function for character strings in conventional document processing devices such as word processors is simply a function for replacing character strings with each other by replacing a search string with a replacement string. Furthermore, as shown in Japanese Patent Application Laid-Open No. 63-167960, there is also a system having a function of validating the character attribute at the beginning of a search string also for a replacement string.

Also, ``Practical UNIX System'' (published by Kogakusha, Mar.
Written by K, G, 5obe11, Translated by Takeshi Angoin, 456-465
), some methods implement string searches using regular expressions.

[Problem to be solved by the invention]

In the above conventional technology, it is possible to replace a specific character string with another character string, but for example, consider searching for a part in a text that references a figure and changing the character attributes of the reference part. With the search function for specific strings, if you use "figure" as the search string, the search will select not only figure references but also unrelated strings such as "shape", which is inefficient. There was a problem. In addition, when specifying a search string using a regular expression, it is possible to select only the figure reference position by searching, but in order to change the character attributes of the reference location, exit search mode and set the character attributes. You had to use the functions to set character attributes one by one, and then enter search mode to continue searching. As described above, the conventional system has a problem in that it is limited to a search and replace function between character strings, and does not consider changing character attributes at the same time.

In addition, in the search function using regular expressions, character attributes cannot be specified as regular expressions.
rcOMPυTERJ written in uppercase and lowercase letters
When searching for and rcOlffiPuterJ, it is necessary to write them separately using regular expressions.

The purpose of the present invention is to provide a string search function that allows regular expressions as search strings and to specify character attributes for each regular expression when performing string search and replacement processing, and to provide a string search function that allows only strings to be used as replacement data. It is an object of the present invention to provide a document processing device in which character attributes can also be set at the same time.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a means for specifying a search string according to a regular expression, a means for specifying character attributes of a search string in units of regular expressions, and a regular expression character search function with 5-character attributes.

The replacement string specification means combines the conventional character string input function and character attribute specification function, and in the replacement process, after replacing the character string found by the search with the replacement string, the specified character attribute is This is achieved by setting.

[Effect]

The above method has a simple string replacement function between the search string and replacement string, a function to set character attributes to the search string,
It consists of functions to replace search strings with replacement strings and to set character attributes.

It performs search and replace functions continuously.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a processing flow of the attribute string replacement method 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
Text data and commands input from are input to the register 120 via the interface circuit 110,
Read by CPt1130. CPt1130 is
A control program stored in memory 140 is executed in response to an input command. Memory 141 is a memory that stores document data. The contents of the memory 141 are “
The document file 150 can be accessed by
The document is expanded into the memory 141 and stored from the memory 141 into the document file 150 by the "Document storage" command. When the document data in the memory 141 is updated by the document editing function, the CPU 130 converts the edited document data into display data, which is sequentially transferred to the bit map processor (BMP) 160. BMP160 is
The display data is developed on the frame memory 170 and transferred to the CRT.
The controller 180 sequentially reads out the contents of the frame memory 170 and develops them onto the CRT 190.

Next, the processing flow of the attribute string replacement method will be explained using FIG. First, when the user selects the character string search function, the search definition sheet 200 shown in FIG. 3 and FIG.
Enter 0.

(Step 10) Here, the input character string may be written as a general character string, written using a regular expression, or written as a combination of a plurality of regular expressions. The regular expression used in this example is based on UNIX (Kogakusha's "Practical UNIX System")
465) and has the following special characters.

"°": When it starts with ", it means the character string at the beginning of a paragraph (the character string between line breaks or page breaks). When it starts with ', it means the first character of the paragraph.

r$": When ending with $, it means the character string at the end of the paragraph. When only $ is used, it means the last character of the paragraph.

r [,,,] J: means any one character from , , . Range specification like C knee 02 and 01
Selection formats such as C2C3 may be mixed.

r[', , koJ: 1 that does not match any of , ,
means one character. Range specification such as C, -C,
Selection formats such as C-C2C may be mixed.

``rC umbrella'': means zero or more repetitions of the letter C.

"Umbrella": means any character string.

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

[\(''``\)'': Means the beginning and end of regular expressions when combining regular expressions.

In this embodiment, using Figs. 3, 4, and 5, we will search for a search string written in a regular expression in the text and change the character attributes of the found string (first Example) will be explained. Also, using Figures 6, 7, 8, and 9, search for strings with attributes added to the search string written using the combined regular expression, and Next, a case (second embodiment) in which character string replacement and attribute change are performed in units of regular expressions will be explained.

First, with reference to FIGS. 3, 4, and 5, a case will be described in which a search character string written in a regular expression is searched from a text and the character attributes of the found character string are changed.

Using regular expressions in the search string definition area 210 of the search definition sheet 200 in FIG.
] *, [i-9] [0-91*]. This is a regular expression that expresses a string consisting of one or more numeric characters starting with ``Figure 1'', followed by ``,'' and a non-zero number at the beginning, and ``Figure X, XJ''. The figure number reference position with the format is searched.

Next, use the search string attribute specification selection field 220 in the search definition sheet 2oo to determine whether or not to specify attributes for the search string. Select "None". (Step 20
) In the first embodiment, "None" was selected. If "Yes" is selected, the process proceeds to the search string attribute input (step 21), but step 21 will be described in detail in the second embodiment.9 Next, replacement processing is performed on the search string. Character replacement selection field 23 in the search definition sheet 200
0 is used to perform replacement, select "Yes", and select "No" when performing only a search (step 30).

When performing a replacement, a replacement character string is input into the replacement character insertion field 240 in the search definition sheet 200 (step 31).

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

Here, when "&" is input as a special character to the replacement character insertion canilia 240, it means that the search character string is used as is. In other words, it is used when only changing attributes.

Next, search definition sheet 2 determines whether or not to perform character attribute replacement.
Using the replacement character string attribute designation selection field 250 in 00, select "Yes" if character replacement is to be performed, or "No" if character replacement is not to be performed (step 40).

Here, if you enter "&" as the replacement string and select "None" for character attribute replacement (the search string and replacement string are the same and there is no attribute change), it will not make sense as a process. It is treated as an error. Further, when 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 character replacement.

If character attribute replacement "Yes" is selected in step 40,
A replacement character string attribute definition sheet 300 as shown in FIG. 4 is displayed, and a character attribute to be set is selected (step 41).

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

In this embodiment, the replacement character string attribute definition sheet 300 is [
Typeface J310. r double angle J320. r underline J3
30. r character type J340. r alphabet” 350
However, it is possible to expand it according to the character attributes of the system.

Here, the font 310 is "Gothic".

Double angle 320 is "width double", underline 330 is "with underline", 4 character type 340 is "change heat"
, it is assumed that "change heat" is selected as the alphabet 350.

After selecting each attribute, if the execution field 360 in the replacement character string attribute definition sheet 300 is selected, the process returns to the search definition sheet 200 with the value selected as the character attribute as the valid value. If the cancel field 370 is selected, the value selected as the character attribute becomes invalid and the process returns to the search definition sheet 200.

After returning to the search definition sheet 200 and selecting the execution field 260 in the search definition sheet 200, the search definition sheet 200 and replacement string attribute definition sheet 300 are displayed.
The value selected in is set as valid, and the process proceeds to character string search processing 50. Furthermore, if the cancel field 270 is selected, the search process is ended.

When a corresponding character string is found by the character string search process 50, a character string replacement process is performed based on the information set in the search definition sheet 1-200 and the replacement character string attribute definition sheet 300. First, the presence or absence of character replacement is determined according to the information selected in the character replacement selection field 230 of the search definition sheet 200 (step 60). If there is a replacement, it is determined whether the search string and the replacement string are the same (step 70). The same means that the input data to the replacement character engraving canilia 240 in the search definition sheet 200 is "&". If the search and replacement character strings are different, character string replacement processing (step 71) is performed.

String replacement processing, similar to what is done in conventional document processing, replaces a string found by a search with a replacement string, and the number of characters in the search string and replacement string are the same. There's no need. Furthermore, if the search and replacement character strings are the same, the one character string replacement process 71 is skipped.

Next, in accordance with the information selected in the character attribute replacement selection field 250 of the search definition sheet 1-200, it is determined whether an attribute change is necessary (step 80). If an attribute change is required, character attribute setting processing (step 81) is performed. The character attribute setting process is the same as the character attribute setting function in conventional document processing systems, and is performed using the attribute setting sheet 30.
The character attribute selected in 0 is set to the target character string.

In addition, if attribute change is not necessary, character attribute setting processing 81
Skip.

Next, if there is no shield replacement in step 60, or if the character string replacement process 71 and character attribute setting process 81 are completed,
It is selected whether or not to continue the search (step 90).

If the process is to be continued, the process returns to the character string search process 50, and if the process is not to be continued, the process is ended.

FIG. 5 shows an example in which a search and attribute-attached character string replacement were actually performed according to the processing flow described above. Same figure (
In the original document 400 of a), 1 Figure 2, IJ 410 and 1
There are two search target character strings 420 in Figure 2.2J. In contrast, search definition sheet 200.
Gothic font using the replacement character string attribute definition sheet 300,
The image with horizontal double and underline attributes is shown in figure (b).
It is. The document 430 after processing is
0 and ``Figure 2.2J 450 is Gothic 1x angle.

It was changed to underlined text, and the layout was changed accordingly.

In the above embodiment, the replacement is automatically performed all at once, but in order to enable the user to select whether or not to perform the replacement (successive replacement), steps 60 and 7o in FIG. This can be easily realized by performing user selection processing during the process.

Next, using Figure 6, Figure 7, Figure 8, and Figure 9, search for a character string with attributes added to the search string written by the combined regular expression, and add the found character string. On the other hand, a case (second embodiment) in which character string replacement and attribute change are performed in units of regular expressions will be described.

Using the regular expression connected to the search string definition area 210 of the search definition sheet 200 in FIG.
Enter "uter\)\([0-9]*\)".

This consists of two regular expressions separated by "\(" and "\)", and "[\(computer\)"]
500 represents the computer itself, and is ``¥(
[0-9] Umbrella\) J510 searches for character strings with the form ``rcomputer numeric string'' that expresses a numeric string containing 0.

Next, select "Yes" in the search character string attribute designation selection field 220 in the search definition sheet 200, and proceed to input the search character string attribute (step 21). Here, the search string in the search string input field 210 can be specified in units of regular expressions, and the search string attributes can be input in units of the specified regular expressions. If no range is specified in the search string input field 210, the search string attribute is valid for the entire search string.

The search string attribute input 21 displays a search string attribute definition sheet 600 shown in FIG. In this embodiment, the search character string attribute definition sheet 600 is “Typeface J610.
r times angle” 620. r underline” 630. r character type” 640. [Alphabet] 650, but it can be expanded according to the character attributes of the system.

Here, it is assumed that "r-no distinction" has been selected for all items. In other words, a search character string with a character code corresponding to the search character string is found regardless of character attributes.

After selecting each attribute, when the execution field 660 in the search character string attribute definition sheet 600 is selected, the process returns to the search definition sheet 200 with the value selected as the character attribute as the valid value. If the cancel field 670 is selected, the value selected as the character attribute becomes invalid and the process returns to the search definition sheet 200.

Next, select whether or not to perform replacement processing on the search string using the character replacement selection field 20 in the search definition sheet 20o.
0 is used to perform replacement, select "Yes", and select "No" when performing only a search (step 30).

When performing a replacement, a replacement character string is input into the replacement character insertion field 240 in the search definition sheet 200 (step 31).

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

Here, if you enter "\Number" as a special character in the replacement character insertion canilia 240, and the search string is expressed by a combination of regular expressions, you can check the number of regular expressions from the beginning of the regular expression. It is expressed as a number and becomes the replacement string corresponding to the regular expression.

In the embodiment of the bookcase 2, in the replacement character inserting canilia 240,
I entered "computer ¥2". This means that the part corresponding to the first regular expression is changed to "computer" 530, and the part corresponding to the second regular expression is [¥24,540], indicating that no character string replacement is performed.

Next, search definition sheet 2 determines whether or not to perform character attribute replacement.
Using the replacement character string attribute designation selection field 250 in 00, select "Yes" if character replacement is to be performed, or "No" if character replacement is not to be performed (step 40).

If character attribute replacement "Yes" is selected in step 40,
The replacement character string attribute definition sheet 300 shown in FIG. 8 is displayed, and the character attribute to be set is selected (step 41). Here, the replacement string in the replacement string input field 240 can be specified in units of regular expressions, and the replacement string attributes can be input in the specified regular expression units. If no range is specified in the replacement string input field 240, the replacement string attribute is valid for the entire replacement string. In this second example, the part “¥2J 530” is selected and the
It is assumed that the replacement character string attribute definition sheet 300 shown in the figure is displayed.

In the second embodiment, the replacement character string attribute definition sheet 300
, the font 310 is "Gothic" 9x 32
It is assumed that ``normal double'' is selected as 0, ``no underline'' is selected as the underline 330, ``full-width'' is selected as the two-character type 340, and ``change heat'' is selected as the alphabet 350.

After selecting each attribute, if the execution field 360 in the replacement character string attribute definition sheet 300 is selected, the process returns to the search definition sheet 200 with the value selected as the character attribute as the valid value. If the cancel field 370 is selected, the value selected as the character attribute becomes invalid and the process returns to the search definition sheet 200.

After returning to search definition sheet 200, search definition sheet 1
When the execution field 260 in ~200 is selected, the search definition sheet 200 and the search string attribute definition sheet 6 are displayed.
00 and the value selected in the replacement character string attribute definition sheet 300 are validated and the process proceeds to character string search processing 50. Furthermore, if the cancel field 270 is selected, the search process is ended.

When a corresponding character string is found by the character string search process 50, a character string replacement process is performed based on the information set in the search definition sheet 200 and the replacement character string attribute definition sheet 300. First, the presence or absence of character replacement is determined according to the information selected in the character replacement selection field 230 of the search definition sheet 200 (step 60). If there is a replacement, it is determined whether the search string and the replacement string are the same for each regular expression (step 70). The same means the replacement character engraving Canilia 2 in the search definition sheet 200.
The input data to 40 is "¥ number". If the search and replacement character strings are different, character string replacement processing (step 71) is performed for each regular expression. The string replacement process is
Similar to what is done in conventional document processing, a character string found through a search is replaced with a replacement string, and the number of characters in the search string and replacement string do not have to be the same. Furthermore, if the search and replacement character strings are the same, the character string replacement process 71 is skipped.

Next, in accordance with the information selected in the character attribute replacement selection field 250 of the search definition sheet 200, it is determined whether an attribute change is necessary (step 80). If an attribute change is required, character attribute setting processing (step 81) is performed.

The character attribute setting process is the same as the character attribute setting function in a conventional document processing system, and is performed using the attribute setting sheet 300.
The character attribute selected in is set to the target character string.

In addition, if attribute change is not necessary, character attribute setting processing 81
Skip.

Next, if there is no replacement in step 60, or if the character string replacement process 71 and character attribute setting process 81 are completed,
It is selected whether or not to continue the search (step 90).

If the process is to be continued, the process returns to the character string search process 50, and if the process is not to be continued, the process is ended.

FIG. 9 shows an example in which a search and attribute-attached character string replacement were actually performed according to the processing flow described above. Same figure (

In the above embodiment, the replacement is automatically performed all at once, but in order to enable the user to select whether or not to perform the replacement (sequential replacement), steps 50 and 60 in FIG. This can be easily realized by performing user selection processing during the process.

〔Effect of the invention〕

According to the present invention, when adding the same character attribute to a character string that matches a certain pattern, the character attribute setting function can be implemented as part of the search replacement process, improving user operability and work efficiency. improves.

In addition, by expressing the search string and replacement string by combining regular expressions, and by making it possible to define character attributes for each regular expression, variations in search and replacement are increased.
- It is possible to perform various character string replacements at once, improving work efficiency.
