Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device provided in a word processor or a computer.

A document editing device is an essential means for document creation work and source program creation work, and is provided in most information processing systems. In addition, the efficiency of the document creation work and the source program creation work greatly depends on whether or not the document creation device is easy for the user to use.

In this specification, a document or a source program to be edited by the document editing apparatus is called a document. Also, the letters, numbers, symbols, etc. included in the document are simply referred to as letters.

2. Description of the Related Art FIG. 16 shows a block diagram of a conventional document editing apparatus. In the conventional document editing apparatus shown in FIG. 16, the editing processing unit 210 performs the document editing process based on a character string or a command input by the user via the keyboard 201, and the obtained document is stored in the text buffer 221. It is configured to hold. Based on the contents of the text buffer 221, the edit processing unit 210 creates display data representing the document being edited, and the display device 202 displays the document based on the display data.

Further, the internal storage 222 stores information about the cursor position which is the starting point of the editing process and information about the correspondence between the label designated by the user and the line number. According to the instructions from the user,
The editing process is performed with reference to the internal storage 222.

A character string search unit 211 of the edit processing unit 210
Displays the character string specified by the user in the text buffer 221.
And the position of the corresponding character string is returned as the search result. In response to this, the edit processing unit 210
Moves the cursor position to the position obtained as the search result.

All character strings input by the user via the keyboard 201 are stored in the text buffer 2 as a document.
The text buffer 2 is written in the text buffer 21 when the document editing work is finished or when the user gives an instruction.
The contents of 21 are stored in the text file 231.

In the process of creating a source program, it is often the case that the range of the function definition portion currently being edited is confirmed or another function definition portion is referred to. In such a case, the user expects that the cursor will move to the corresponding position by starting the search process by specifying the pattern indicating the start or end of the function definition part and the function name to be referenced. .

[0009]

The character string search unit 211 of the conventional document editing apparatus described above treats the document as a series of characters, and does not distinguish between the function name and the character string in the comment text. Therefore, even if a character string indicating a function name is designated to perform a search, the character string included in the comment text may be searched, and the expected character string is not always searched.

When the function definition portion being edited does not completely arrange the appearance of the function, the cursor is positioned at the beginning or end of the function by searching for the start pattern or end pattern of the function definition portion. You cannot move.

In the conventional document editing apparatus, in such a case, the user scrolls the screen to find a desired portion. As described above, it has been impossible to reliably meet the user's request only with the search function of the conventional document editing apparatus.

Further, in the conventional document editing apparatus, since the input character strings are all treated as the contents of the document,
Even if you wanted to temporarily add a comment to a certain area of the source program, you had to enter it in the form of comment text. However, many comments that you want to add temporarily do not need to be left after the source program creation work is completed.In that case, the user writes the comment contents. You have to find it and delete it. Since this work is complicated, the user often dares not to write a temporary comment sentence, which may cause an unexpected mistake.

As described above, the conventional document editing apparatus is difficult for the user to search the area and process the annotation text. SUMMARY OF THE INVENTION It is an object of the present invention to provide a document editing device that facilitates the process of searching an area in a document.

[0026]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 4 is a block diagram of an embodiment of the document editing apparatus according to the first aspect.

In FIG. 4, the document editing apparatus according to claim 1 is configured by adding an attribute value buffer 223 and an attribute value file 232 to the conventional document editing apparatus shown in FIG. In addition, the edit processing unit 210 uses the character string search unit 21.
In addition to 1, the attribute value generation unit 212, the read processing unit 213, and the determination unit 214 are included. In this edit processing unit 210, the input analysis unit 215 is a keyboard 20.
The input analysis unit 215 analyzes the instruction input from
Each of the character string search unit 211, the attribute value generation unit 212, the read processing unit 213, and the determination unit 214 operates in accordance with the instruction from.

In FIG. 4, the same parts as those of the conventional document editing apparatus shown in FIG. 16 are designated by the same reference numerals. The attribute value buffer 223 corresponds to the attribute value storage means 114, and for example, the document storage means 1
The attribute value described later is stored corresponding to each character stored in the text buffer 221 corresponding to 11. Further, the attribute value file 232 is provided with an attribute value file 232 corresponding to the text file 231. The correspondence relationship between the text file 231 and the attribute value file 232 may be specified by a file name or the like.

The operation of the document editing apparatus according to claim 1 will be described below. First, the operation of setting an attribute value in a document will be described. When the user operates the keyboard 201 and inputs an instruction to set an attribute value, the input analysis unit 215 activates the attribute value generation unit 212 and gives an instruction to set the attribute value. In response to this, the attribute value generation unit 212
First, requests input of a range in which the attribute value is set, and when the range is input, the attribute value is generated corresponding to the area indicated by this range and is sent to the attribute value buffer 223. The attribute value buffer 223 stores this attribute value corresponding to each character included in the above range.

Here, the attribute value generation unit 212 generates a character code for one character that has not been used as an attribute value until then, in accordance with an instruction to set the attribute value, and this character code is used. Should be sent to the attribute value buffer as an attribute value corresponding to each character in the above-mentioned area.

In this way, the keyboard 201, the input analysis unit 215, and the attribute value generation unit 212 realize the functions of the range designating unit 112 and the attribute value setting unit 113, and the attribute value is set in the area designated by the user. It can be set and held in the attribute value buffer 223 corresponding to the attribute value storage means 114.

After that, when the insertion of the character string is instructed to the area where the attribute value has already been set, the input analysis unit 215
Instructs the attribute value generator 212 to generate an attribute value. In response to this, the attribute value generation unit 212 determines that the attribute value buffer 22
3 is obtained to obtain the attribute value set to the immediately preceding character, and the attribute value buffer 22 stores the attribute value for the number of characters to be inserted.
Send to 3. The attribute value buffer 223 may insert and store the input attribute value in a corresponding place.

Next, a method of searching the boundary of the area using the attribute value will be described. FIG. 5 is a flowchart showing the boundary search operation of the area. Keyboard 20 depending on user
When 1 is operated and it is instructed to move the cursor position to the boundary of the area, the input analysis unit 215 instructs the reading processing unit 213 to perform the attribute value reading operation. At this time, the input analysis unit 215 may indicate the direction of advancing the reading process depending on which side of the region the boundary is instructed. That is, when it is instructed to move the cursor position to the beginning of the area, the attribute value search unit 213 is instructed to read the document forward, and the cursor is moved to the end of the area. On the contrary, when instructed, the backward reading process of the document may be instructed.

In response to the instruction from the input analysis unit 215, the read processing unit 213 first reads the attribute value corresponding to the current cursor position from the attribute value buffer 223 and sends it to the determination unit 214 (step 301). The determination unit 214 holds this attribute value (step 302). Next, the attribute values corresponding to the characters continuing from the current cursor position in the designated direction are sequentially read from the attribute value buffer 223 (step 303) and sent to the determination unit 214. The determination unit 214 determines whether this attribute value matches the attribute value obtained in step 302 (step 304).

In the case of a positive determination in step 304, since the corresponding character belongs to the same area as the character at the cursor position, the determination unit 214 causes the read processing unit 213 to
Returning to step 303, it is instructed to read the attribute value corresponding to the next character.

On the other hand, in the case of a negative judgment in step 304, it is considered that the character read in step 303 is included in a region different from the character at the cursor position. Therefore, in this case, the determination unit 214 may determine that the boundary of the area has been detected, and output the position of the character corresponding to the attribute value read before the corresponding character as the detection result (step 305). Note that in step 303,
When 304 reaches the beginning or the end of the document by repeating 304, the position of the beginning or the end of the document may be output as the detection result.

In response to this, the edit processing unit 210 changes the cursor position in the internal memory 222 to the position indicated by the detection result obtained in step 305, and based on this cursor position and the contents of the text buffer 221, And the display data is updated (step 306). As a result, the cursor position moves to the boundary of the area being edited, and the portion of the document including the boundary of this area is displayed on the display device 202.

As described above, the read processing unit 213 and the determination unit 2
14 operates according to the instruction from the input analysis unit 215, the function of the detection unit 115 can be realized to detect the change point of the attribute value, and the boundary of the area in the document can be easily detected. It becomes possible.

As a result, the cursor position can be quickly moved to the start or end position of the area currently being edited, and the start or end portion of the corresponding area can be confirmed, so that the document editing work can be performed efficiently. You can proceed.
In particular, in the process of creating a source program, it is often desirable to check the beginning or end of the function definition part being edited, so the effect of applying the invention of claim 1 is great, and the document editing is easy for the user to use. A device can be provided.

When it is instructed to end the editing process, the contents of the text buffer 221 are saved in the text file 231, and the attribute value buffer 223 is also stored.
If the contents of is stored in the attribute value file, the previously set attribute value can be used when the same document is edited later.

Furthermore, if the user can specify the "name" for the attribute value that is mechanically set on the document editing device side, the correspondence between each area and the attribute value set in that area The user can intuitively understand the relationship.

FIG. 6 shows a block diagram of an embodiment of the document editing apparatus according to the second aspect. 6, the document editing apparatus according to claim 2 is the same as the document editing apparatus shown in FIG.
And an attribute value table 224 are added.
However, in FIG. 6, the same parts as those of the document editing apparatus shown in FIG. 4 are designated by the same reference numerals.

The character string setting unit 216 is the input analysis unit 215.
The attribute value buffer 223 and the attribute value table 224 are accessed according to the instruction from the. The attribute value table 224 is the character string storage unit 1.
It corresponds to No. 22 and can be accessed from the read processing unit 213 and the character string setting unit 216.

In this case, for example, when the user designates a desired range of a document as an area, an appropriate character string is input through the keyboard 201 as a name of the area (hereinafter referred to as an area name). , According to this, the input analysis unit 21
5 may be sent to the above-mentioned character string setting unit 216.
At this time, by inputting a function name or the like defined in the area, it is convenient because the correspondence between the area and the area name can be intuitively grasped.

At this time, the character string setting section 216 refers to the attribute value buffer 223 to obtain the attribute value corresponding to the character at the cursor position, and sends this attribute value to the attribute value table 224 together with the area name mentioned above. To do. Accordingly
The attribute value table 224 may store the attribute value and the area name described above in combination.

In this way, the function of the character string input means 121 is realized by the keyboard 201, the input analysis unit 215, and the character string setting unit 216, and a desired character string is set and held corresponding to each area. You can keep it.

Note that a character string can be set in the same manner even for an area for which an attribute value has already been set. The operation of searching the area corresponding to the character string according to the designation of the character string will be described below.

FIG. 7 is a flow chart showing the operation of searching the area corresponding to the area name. Keyboard 20 depending on user
When 1 is operated and it is instructed to search the character string and the area corresponding to this character string, the input analysis unit 215 activates the read processing unit 213 by designating this character string (step 401). .

In response to this, the read processing unit 213 first obtains the attribute value corresponding to the designated area name by referring to the attribute value table 224 and sends it to the determination unit 214 (step 402), and the determination unit. 214 holds this attribute value. Next, the reading processing unit 213 refers to the attribute value buffer 223, sequentially reads from the attribute value corresponding to the beginning of the document, and sends it to the judging unit 214 (step 403).
4 determines whether this attribute value matches the attribute value obtained in step 402 (step 404).

In the case of a negative determination in step 404, the determination unit 214 determines that it is not the corresponding area, and instructs the read processing unit 213 to return to step 403 and read the attribute value corresponding to the next character.

On the other hand, if the affirmative judgment is made in step 404, the judgment unit 214 judges that the corresponding area is detected, and the position of the character in the document corresponding to the attribute value obtained in step 403 is used as the search result. Output (Step 4)
05). In response to this, the edit processing unit 210 changes the cursor position in the internal storage 222 to the position indicated by the search result, and the cursor position and the text buffer 22 are changed.
The display data is updated based on the contents of 1 (step 406). This display data is sent to the display device 202, and in response, the display device 202 displays this area of the document.

In this way, the function of the area search means 123 is realized by the operation of the read processing section 213 and the determination section 214 according to the instruction from the input analysis section 215.
By utilizing the correspondence between the attribute value and the area name held in the attribute value table 223, the user can search the area specified by the area name.

As a result, regardless of the current cursor position, it is possible to quickly move the cursor position to the beginning of the area designated by the user. For example, since the cursor can be easily moved from the part being edited to another function definition part, the work of creating the source program can be carried out more efficiently.

In this case, when it is instructed to end the editing process, the contents of the attribute value buffer 223 and the contents of the attribute value table 224 are changed to the attribute value file 2
Save it to 32.

The character string stored in the above-mentioned attribute value table 223 corresponding to each area may be a comment about the area. For example, in the work of creating a source program, it is conceivable to temporarily hold ideas and cautions that have come up during the work in correspondence with the corresponding areas. In such a case, it is convenient if the character string held corresponding to the area can be referred to as needed.

FIG. 8 shows a block diagram of an embodiment of the document editing apparatus of the third aspect. In FIG. 8, the document editing apparatus of claim 3 is configured by adding a display data creating unit 217 to the document editing apparatus of claim 2 shown in FIG.

The display data creation unit 217 is configured to create display data for displaying the character string based on the input character string and send it to the display device 202.

In this case, similarly to the area name described above, the attribute value table 224 corresponds to the attribute value set in the character at the cursor position in the character string input by the user.
You can store it in.

FIG. 9 is a flowchart showing the operation of displaying the character string set in the area. Keyboard 2 by user
When 01 is operated and it is instructed to display the character string set in the area, the input analysis unit 215 specifies the current cursor position and activates the read processing unit 213 (step 501).

In response to this, the read processing unit 213 refers to the attribute value buffer 223 based on the designated position to obtain the attribute value corresponding to the character at the cursor position (step 502). Next, the read processing unit 213 reads the character string corresponding to this attribute value from the attribute value table 224 (step 503) and sends it to the display data creation unit 217.

As described above, the read processing unit 213 operates in accordance with the instruction from the input analysis unit 215, thereby realizing the function of the read unit 131, and the character string held corresponding to the designated area. Can be read.

The display data creating section 217 creates display data based on this character string (step 504), and instead of the display data created by the editing processing section 210 based on the contents of the text buffer 221, the display data is created in step 504. The obtained display data may be sent to the display device 202.
In response, the display device 202 causes step 503
The character string obtained by is displayed.

In this way, the display data creation unit 217
With the display device 202, the function of the display unit 132 can be realized, and the character string added to the area to which the cursor position belongs can be displayed and provided to the user.

As a result, the user can add a comment or the like corresponding to a part of the document and refer to this character string when necessary. Here, the character strings set corresponding to the attribute values are stored separately from the document, so it is not necessary to delete these character strings from the document when the source program creation work is completed. Absent.

Therefore, the user can easily add an idea or caution that he / she has come up with, without the trouble of deleting it later. Therefore, a mistake caused by such an annotation being overlooked can be avoided. This can be prevented in advance, and the document editing work can be advanced efficiently.

After that, when the user gives an instruction to end the display of the character string, the edit processing unit 210
The original display data may be reproduced based on the contents of the text buffer 221 (step 506) and sent to the display device 202 to end the process.

By the way, there may be a case where it is desired to leave the above-mentioned annotation as it is as the annotation statement in the source program. In such a case, it would be convenient if the character string stored corresponding to the attribute value could be converted into the format of the annotation sentence and inserted into the document.

FIG. 10 shows a block diagram of an embodiment of the document editing apparatus of claim 4. 10, the document editing apparatus according to claim 4 has a configuration in which an insertion control section 218 and an annotation pattern storage section 225 are added to the document editing apparatus according to claim 3 shown in FIG.

The annotation pattern storage unit 225 described above stores, for example, a start pattern “/ *” and an end pattern “* /” as patterns indicating an annotation sentence. In addition, the insertion control unit 218 is configured to output a specified character string and this pattern as a character string to be inserted into a document in response to an instruction from the input analysis unit 215.

A method of inserting a character string held corresponding to an attribute value into a document will be described below. FIG. 11 is a flowchart showing the operation of inserting a character string.

When the user operates the keyboard 201 to instruct the insertion of the character string added corresponding to the attribute value, the input analysis unit 215 specifies the cursor position and activates the read processing unit 213. Then, it is instructed to send the read character string to the insertion control unit 218 (step 60).
1).

In response to this, the read-out processing unit 213 operates as the read-out means 141, and the above-mentioned steps 502 and 50 are executed.
Similarly to 3, the character string added corresponding to the area to which the cursor position belongs is read and sent to the insertion control unit 218 (step 602).

The insertion control unit 218 starts the operation in response to the input of the character string, and first inquires the user whether or not to convert the character string into the form of the annotation sentence (step 603).

If the user gives an instruction to convert to the annotation text format, the affirmative judgment is made in step 603, and the insertion control section 218 obtains the start pattern in the annotation pattern storage section 225 and the step 602. The character string and the end pattern are sequentially sent to the text buffer 221 (steps 604 to 606). This allows
These strings are inserted into the document.

On the other hand, in the case of a negative judgment in step 603, the insertion control section 218 may send only the character string obtained in step 602 to the text buffer 221 (step 607). In response, only the character string obtained in step 602 is inserted into the document.

In addition, the above-mentioned insertion processing (step 604)
~ After the end of step 607), the insertion control unit 218
The attribute value generator 212 is activated via the input analyzer 215. In response to this, the attribute value generation unit 212 operates, and the attribute value setting process for the inserted character string is performed in the same manner as the attribute value setting process for the character string input via the keyboard 201 (step 608). After this processing ends, the insertion control unit 218 may determine that the character string insertion processing has ended, and end the processing.

As described above, the insertion control unit 218 and the annotation pattern storage unit 225 operate according to the input of the character string from the read processing unit 213, thereby realizing the function of the insertion unit 142 and corresponding to the area. It is possible to hold the added character string as a document.

As a result, only the necessary character strings can be selectively included in the document from the character strings added to each area. In this case, the user can easily hold a character string indicating a caution or the like that was conceived during the document editing work, and can convert the corresponding character string into a document by a simple operation. Therefore, it is possible to prevent mistakes during the document editing work, and to save the information necessary for managing the source program and the like without omission even after the completion of the document editing work.

By the way, in the source program, the function definition portion and the like are created according to a predetermined pattern defined by the language. Therefore, if the format of the source program is adjusted to a certain extent, it is possible to extract the corresponding area by detecting the pattern indicating the function definition portion and the like.

FIG. 12 shows a block diagram of an embodiment of the document editing apparatus of claim 5. 12, the document editing apparatus according to claim 5 is the same as the document editing apparatus shown in FIG.
9 and an area pattern storage unit 226 are added.

The area pattern storage unit 226 corresponds to the boundary information storage means 151, and as the pattern indicating the boundary of the area, for example, the area start pattern "∧ [a-
zA-Z0-9] ++ ("(however, [a-zA-Z0-
9] indicates lowercase letters and uppercase letters and numbers) and the area end pattern “∧} * $”. The contents of the area pattern storage unit 226 are the same as the contents of the attribute value buffer 223, and
Save it in 2.

In this document editing device, the extraction control unit 2
The control unit 19 controls the character string search unit 211 according to an instruction from the input analysis unit 215, and extracts a region in the document based on the pattern indicating the boundary of the region stored in the region pattern storage unit 226. The extraction control unit 219 also specifies the extracted area and instructs the attribute value generation unit 212 to perform attribute value setting processing. That is, the extraction control unit 219 and the character string search unit 211 function as the area extracting unit 152.

The attribute value setting operation of the document editing apparatus of claim 5 will be described below. FIG. 13 is a flowchart showing the attribute value setting operation. When the user operates the keyboard 201 to instruct to set the attribute value in the document being edited, the input analysis unit 215 activates the extraction control unit 219.

The extraction control unit 219 first sets the search start position to the beginning of the document (step 701), reads the region start pattern from the region pattern storage unit 226, and performs the character string search process for the character string representing this region start pattern. The column search unit 211 is instructed.

In response to this, the character string search unit 211 performs a search operation (step 702), and when a corresponding character string is detected, as a positive determination in step 703, the position where the character string is detected is extracted by the extraction control unit. Return to 219. The extraction control unit 219 holds the position obtained from the character string search unit 211 as the region start position (step 704), reads the region end pattern from the region pattern storage unit 226, and
Using the above-described start position as the search start position, the character string search unit 211 is instructed to search for a character string that represents the area end pattern.

In response to this, the character string search section 211 performs a search operation (step 705) and returns the position where the corresponding pattern is detected to the extraction control section 219. At this time, if the corresponding pattern cannot be detected, the end position of the document may be returned to the extraction control unit 219.

The extraction control unit 219 uses the character string search unit 211.
The position obtained from is held as the end position of the area (step 706), the above-mentioned start position and this end position are designated, and the attribute value generation unit 212 is activated, and this start position and end position are set as boundaries. To set the attribute value corresponding to the area to be edited.

In response to this, the attribute value generator 212 generates a character code for one character that has not been used as an attribute value up to that point, and the character code corresponds to the attribute corresponding to each character in the above-mentioned area. The value is sent to the attribute value buffer 223 (step 707).

After the attribute value setting process is completed, the extraction control unit 219 sets the end position held in step 706 as the search start position (step 708), returns to step 702, and instructs the area start pattern search again. do it.

Steps 702 to 708 described above
When the determination of step 703 is negative, the extraction control unit 219 may determine that the region extraction processing and the attribute value setting processing have ended, and end the processing.

In this way, it becomes possible to extract a portion having a predetermined feature from the document as an area and automatically set the attribute value in the extracted area. Thereby, for example, a portion having a predetermined format, such as a function definition portion, can be automatically extracted as an area and an attribute value can be set for each area.

In this case, since it is not necessary for the user to specify the range of each area, the user can save the labor and the document editing work can be efficiently advanced, and the document editing apparatus can be further improved. It can be easy to use.

By the way, the area start pattern indicating the start of the above-mentioned function definition portion includes a portion "[a-zA-Z0-9] +" indicating the function name defined in that portion. By extracting this portion, it is possible to automatically obtain an appropriate character string as the area name of the area.

FIG. 14 shows a block diagram of an embodiment of the document editing apparatus of claim 6. 14, the document editing apparatus according to claim 6 is configured by adding a character string setting unit 216 and an attribute value table 224 to the document editing apparatus shown in FIG.

In this document editing device, the extraction control unit 2

Instruct the setting process of. Also, a character string indicating the name of the area is extracted from the extracted area, and this character string is stored in the attribute value table 224 via the character string setting unit 216. That is, the extraction control unit 219 and the character string search unit 211 perform the function of the area extraction unit 152, and the extraction control unit 219, the character string search unit 211, and the character string setting unit 216 perform the function of the name detection unit 162. It is configured to fulfill.

In this case, the area pattern storage unit 2
26, together with the pattern indicating the boundary of the above-mentioned area,
The pattern including the area name and the characteristic pattern of the area name may be stored, and the area pattern storage unit 226 may realize the functions of the boundary information storage unit 151 and the name information storage unit 161.

For example, when the function definition portion is extracted as an area, since the area start pattern includes the function name as described above, the area start pattern is stored in the area pattern storage unit 226 as a pattern including the area name. Just store it. Further, the portion "[a-zA-Z0-9] +" indicating the function name in the area start pattern may be stored as the characteristic pattern of the area name.

The attribute value setting operation of this document editing apparatus will be described below. FIG. 15 is a flowchart showing the attribute value setting operation of this document editing device. When the user operates the keyboard 201 to instruct to set the attribute value, the input analysis unit 215 activates the extraction control unit 219, and in response to this, the extraction control unit 219 causes the extraction control unit 219 to save the document. The start is the search start position (step 801), and the character string search unit 21 is executed in the same manner as in steps 702 to 706 described above.
1 is controlled to extract the area in the document (step 80).
2). When the area is extracted in step 802, as a positive determination in step 803, the extraction control unit 219 activates the attribute value generation unit 212 to perform attribute value setting processing for this area (step 804).

Next, the extraction control unit 219 reads the pattern including the area name from the area pattern storage unit 226,
The character string is sent to the character string search unit 211, and the area extracted in step 802 is used as a search range to instruct the search for the corresponding character string.

In response to this, the character string search unit 211 searches for a character string corresponding to the pattern including the area name (step 805), and when a corresponding character string is searched, an affirmative decision in step 806 is made. Extraction control unit 2
Return to 19.

The extraction control unit 219 refers to the characteristic pattern of the area name in the area pattern storage unit 226, and extracts the character string corresponding to the characteristic pattern of the area name from the character string returned from the character string search unit 211. And sends it to the character string setting unit 216 (step 807). In response to this, the character string setting unit 216 refers to the attribute value buffer 223 to obtain the attribute value corresponding to the corresponding area, and sends the above-mentioned character string to the attribute value table 224 together with this attribute value (step). 808). In response to this, the attribute value table 224 stores this character string in combination with the attribute value.
After that, the extraction control unit 219 may set the search start position to the end position of the region (step 809), return to step 802, and give an instruction to restart the search process.

On the other hand, if the pattern including the area name is not detected in step 807, step 80
As a negative determination of 6, the process may proceed to step 809 as it is.

Steps 802 to 809 described above
When the negative determination is made in step 803, the extraction control unit 219 may end the processing by determining that the extraction processing of all areas and the setting processing of the attribute value are completed.

In this way, it becomes possible to automatically extract a character string suitable as the name of the extracted area and hold this character string in the attribute value table 223 corresponding to the area. As a result, for example, a function definition portion or the like can be automatically extracted as an area, and a function name defined in this area can be extracted and held corresponding to this area.

In this case, the user does not need to input the area name for each area. Therefore, it is possible to efficiently perform the document editing work without the user's trouble.
