[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structured document processing device capable of editing a document by inserting figures, tables, graphs, numbers, symbols and the like into the structured document. In recent years, many documents created by word processors or computers are edited by inserting data such as figures, tables, graphs, numbers or symbols into the documents. It is desired that graphics, tables, graphs, data consisting of numbers, symbols, etc. inserted in a document be constantly updated so that the latest data can be referred to. In this specification, character strings, figures, tables, graphs, data consisting of numbers or symbols, etc. handled by the document processing apparatus are referred to as "documents", and chapters, sections,
Significant breaks such as terms, paragraphs, and frames are described as "parts".

2. Description of the Related Art Many document processing apparatuses for creating documents by word processors and computers have been proposed. For example, in Japanese Patent Laid-Open No. 2-291065, when external data is referred to in variable data in a document, an external database is searched, the latest value is calculated, and internal data is referred to. If you want to search the document, calculate the latest value, and see the non-print information in the document, save the non-print information in the document in the document text to create an efficient document. A document processing method that makes it possible is shown. Further, Japanese Patent Laid-Open No. 63-240669 discloses a document processing device which inserts document data based on a reference key inserted at a reference information position.
Further, in Japanese Patent Laid-Open No. 3-110666, the edited document read from the document storage means is displayed on the display means, and when a cursor is directed to a specific area of the edited document, the editing control means causes the editing means to edit the document to the specific area. There is shown a document processing apparatus that suppresses input of information and prevents reorganization of a specific area. Further, the ordinary document processing apparatus has a problem that the reference destination cannot be dynamically changed from the reference document component level inside the document when the document is created or edited.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the document processing method disclosed in Japanese Patent Publication No. 065, reference data is retrieved from an external database, and thus, when the external database is not operating, desired contents of reference data cannot be displayed. Further, the above document processing method has a problem that it takes time to display the content of the reference data on the display device because the external database is accessed. The document processing apparatus disclosed in the above-mentioned Japanese Patent Laid-Open No. 63-240669 has a problem that it does not have a function of editing the document data of the logical structure unit by replacing it with the latest data. The document processing apparatus disclosed in Japanese Patent Laid-Open No. 3-110666 has a problem in that it is impossible to prohibit editing while being aware of a logically structured document.

An ordinary document processing apparatus, when creating a document,
In order to change the contents after importing the reference document part in the document, either update the content of the actual data of the reference destination, or import a new reference document part from the outside and replace it with the existing one. However, the operation was troublesome and time-consuming, leading to editing mistakes.

An object of the present invention is to solve the above problems, and an object thereof is to provide a structured document processing apparatus capable of quickly accessing a logically structured reference component. Another object of the present invention is to provide a structured document processing device capable of editing a logically structured reference component by replacing it with the latest data.

[Work]

(First Invention) A document data file to be processed is held in the document holding means. The reference part information judging means can judge whether or not there is a logical object having reference part information in the document data file held in the document holding means. Further, the user can specify whether or not to retain the actual data of the reference component having the reference component information in the document data file by the retention designation means. When the reference component information determining unit determines that there is a logical object having reference component information, the reference component determining unit determines whether the reference component for the logical object having the reference component information can be used. When the reference component information determining unit determines that the reference component corresponding to the logical object having the reference component information cannot be used, the reference component acquiring unit attempts to acquire the reference component matching the reference component information. When the actual data of the reference component having the reference component information is stored in the document data file, the reference component replacement unit refers to the reference component acquired by the reference component acquisition unit as the old reference in the stored document data file. Replace with parts. The reference component thus obtained is displayed on the document display means together with the other document data file to be processed. When the actual data of the reference part is held in the document data file, for example, even if the document part management database is not operating, the reference part is quickly acquired and displayed on the document display means. It is also possible to have only the reference part information in the document data file, and the reference part can obtain the actual data of the reference part from the document part management database based on the reference part information. Therefore, according to the first aspect of the present invention, it is possible to select whether the actual data of the reference component is stored in the document data file or the document component management database in consideration of the purpose of use and frequency of the reference component.

(Second Invention) In order to distinguish the reference parts referred to from the document data file or the document parts management database from the document parts, the document display means hatches or marks, for example, in the area of the reference parts. It can be displayed with a shade or the like. The document editing means determines whether or not the target is the reference component, and performs the editing process only when the target component is not the reference component. Further, since the structured document has the reference component information, it is possible to prohibit the editing of all the structures below the logical object.

(Third invention) The reference part information changing means can change the reference part information according to a user's instruction. Then, the reference component acquisition means can try to acquire a suitable reference component corresponding to the change of the reference component information by the reference component information changing means. Therefore, the user can dynamically find and change the reference destination in the reference component information in the document data file, and can confirm the content of the reference destination on the spot.

Reference when the component determination means 14 and the reference component corresponding to the logical object having the reference component information cannot be used Reference part acquisition means 15 that attempts to acquire a reference part that conforms to the product information from the document part management database and the reference part acquisition when the actual data of the reference part having the reference part information is held in the document data file. The reference component replacement unit 16 replaces the reference component obtained by the unit 15 with the old reference component in the held document data file.

Further, the structured document processing apparatus includes a document display means 17 capable of editing while displaying a document, a document editing means 18 for editing data of a document data file held in the document holding means 11, and a reference component. The acquisition unit 15 includes an access mechanism 19 for accessing the reference destination information. Then, the structured document processing apparatus uses the network 10 through the access mechanism 19 to access the reference destination information.
A desired reference component can be acquired from the document component management database 26 connected to the.

FIG. 2 is a conceptual diagram showing a method of holding reference component information of a document component management database for explaining an embodiment of the present invention. In FIG. 2, the content display 21 of the document is displayed.
Is composed of, for example, a paragraph A22 formed of characters, a reference component 23 formed of a figure, and a paragraph B24 formed of characters. The document data file 25 is composed of reference part information 23 ′ and document content information 22 ′ and 24 ′ and held in the document holding means 11. The document content information 22 ', 24' is composed of, for example, data 22 'of paragraph A made of characters and data 24' of paragraph B made of characters. The document part management database 26 stores actual data of reference parts based on the reference part information 23 'in the document data file 25. The reference component information 23 'has, for example, storage destination information of the reference component in the document component management database 26, a registered reference component name, a registrant name, a registration date and time, an identifier, and the like. In this specification, "document parts management database"
May be of any format as long as it can manage the database, such as a file server. Then, when the document is edited, the paragraph A22 and the paragraph B24 are displayed on the document display device based on the data 22 'and 24' in the document data file 25, respectively. The reference component 23 is obtained from the document component management database 26 based on the reference component information 23 ′ in the document data file 25 and displayed on the document display means 17.

FIG. 3 is a conceptual diagram showing a method of holding reference information and actual data of parts for explaining an embodiment of the present invention. In FIG. 3, the document content display 21 and the document component management database 26 are the same as those in FIG. The difference from FIG. 2 lies in the document data file 25 '. That is, in the document data file 25 'shown in FIG. 3, the data 22' of the paragraph A consisting of characters, the reference part information 23 'consisting of the graphic, the actual data 27 of the reference parts, and the data of the paragraph B consisting of the characters. 24 '.
When the document is edited, the document content display 21 is based on the data 22 'of the paragraph A, the actual data 27 of the reference part, and the data 24' of the paragraph B from the document data file 25 '. Is displayed in. The reference part information 23 'is necessary only when the reference part is updated.

FIG. 4 is a flow chart for explaining a case of selecting a data holding method in a file. A method for importing a document data file according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 4. When the user requests a reference component while editing a document, the document processing apparatus prompts the user to instruct a data holding method (step 41). For example, two data holding methods are displayed in a window of the document display means 17,
The user selects one of them. The document processing apparatus determines whether the user's selection is a method of holding actual data (step 42). If the user does not select to hold the actual data by the holding designation means 13, the process proceeds to step 43, and if the user selects to hold the actual data, the process proceeds to step 44. When the holding designation means 13 selects one that does not hold the actual data, only the reference component information 23 'is fetched from the document component management database 26 into the document data file 25 (step 43). When the holding designation means 13 selects the one holding the actual data, the actual data 27 from the document parts management database 26 and the reference information 2
3'is taken into the document data file 25 '(step 44).

FIG. 5 is a flow chart for explaining the display of reference parts. The content display of the document according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 5. The document processing device confirms whether the method of holding the document data file selected by the user is the method of FIG. 2 or FIG. 3 (step 51). Step 5 of the document processing apparatus
According to 1, it is determined whether or not the actual data of the part is held (step 52). That is, it is determined whether or not the document data file 25 or 25 'held in the document holding means 11 contains the actual data of the reference part. If the actual data of the reference part is not stored, the process proceeds to step 53, and if the actual data is stored, the process proceeds to step 54.

If the user does not select to retain the actual data, the reference component acquisition means 15 stores the actual data from the document component management database 26 based on the reference component information 23 'of the document data file 25. It is acquired and displayed on the document display means 17 (step 53). When the user selects to retain the actual data, the reference component acquisition unit 15
Acquires the actual data 27 of the reference part in the document data file 25 'and displays it on the document display means 17 (step 54). At this time, when the actual data 27 of the reference part having the reference part information 23 'is held in the document data file 25', the reference part replacement means 16 replaces the reference part acquired by the reference part acquisition means 15. , Replaces the previously-referenced document data file with the old reference component.

As described above, the document data file is held by a method of holding the actual data 22 'and 24' of the document parts and the reference part information 23 ', and the actual data 2 of the document parts.
2'and 24 ', and a method of holding the reference part actual data 27 and the reference part information 23'. The method of holding the actual data 27 of the reference parts and the reference part information 23 'can promptly display the contents on the document display means 17 regardless of the operating state of the document parts management database 26. In addition, the above two methods can reduce the addition of processing to be emphasized by allowing the user to select the holding method.

FIG. 6 is a block diagram of the structured document processing apparatus according to the second embodiment of the present invention. The difference from the structured document processing device having the logical structure in FIG. 1 is that the part which is the reference part information of the document data file held by the document display means 17 can be displayed in a different mode from the part which is not the reference part information. The point is that the document editing means 18 judges whether or not it is the target reference part information, and the editing process can be performed only when it is not the reference part information.

FIG. 7 is a second embodiment of the present invention and is a diagram for explaining the reference relationship using a logical structure as a model. In FIG. 7, the text represents that it is logically structured. For example, the document logic root (root) 71 is composed of a document part 23 ″ and a reference part 23. The reference part 23 is stored in the document part management database 70 as reference part information 23 ′. It has storage destination information, registered part name, registrant name, registration date and time, etc. The document part 23 ″ is, for example, in the lower section of the first chapter 72, the first section 73.
And a second section 74, each of which has a content 75, 76 under each section. Similarly, the reference component 23 is also logically structured, and if it is a document, it is chapter 77, section 7
8 and their contents 79. The reference part information 23 ′ is stored in the top object of the reference part 23. The reference parts 23 are stored in the document parts management database 70 without the reference parts information 23 '.

FIG. 8 shows the reference relationship in the display image of the document editor in the second embodiment of the present invention. The document display means 17 receives the reference request from the user and outputs the graphic component 8 from the document component management database 70.
When 2'and the front part 83 'are taken in by referring to the document 81, for example, a shade or a hatching is applied to inform the user that the graphic part 82 and the front part 83 are reference parts. Therefore, the user can know whether it is the reference component referred to from the document component management database 70 or the document component in the document data file while looking at the display while editing the document.

Next, the updating process of the reference parts will be described. FIG. 9 is a second embodiment of the present invention and shows a flowchart for collectively updating all reference parts in a document.
Update processing includes batch update processing for updating all the reference parts in the document and individual update for updating only the selected reference parts. In FIG. 9, the logical structure of FIG. 7 is changed from the document logical root (root) 71. Call the batch update while following the sequence.
The reference part information judging means 14 in the document processing apparatus checks whether or not there is "reference part information" in the logic object 77 (step 91). If there is no “reference component information” in the logic object 77, the process returns to the original. When there is reference component information in the logic object 77, the reference component determining unit 14 determines, for example, the registration date and time which is the reference component information in the document data file and the reference component registration date and time in the document component management database 70. And whether or not the reference part is the latest (step 9).
2).

When it is determined that the reference component is not the latest but updated, the reference component acquisition unit 15 passes the reference component information to the document component management database 70. , And requests a reference component that matches the reference component information (step 93). Reference part judging means 1
4 checks whether the latest reference part has been obtained (step 94). If the reference component determining means 14 determines that the reference component is not the latest one, the reference component is left as it is,
Return to the original (step 95). When the latest reference component is acquired by the reference component acquisition unit 15, the reference component replacement unit 16 replaces the original reference component with the latest reference component (step 96). When it is determined in step 92 that the reference component is not the latest, the original reference component is returned as it is without being updated (step 95). Since the reference parts as described above only have the reference part information added to the document parts, the reference parts information is simply discarded to become a normal document part. That is, the document parts that do not have the reference part information are not the target of the update process.

FIG. 10 is a flow chart for carrying out a process for discriminating whether or not the reference component selected in the document editing process or its contents is edit prohibited in the second embodiment of the present invention. The process shown in FIG. 10 is called when an edit event occurs for the reference part or its contents (characters, graphic parts, table parts, etc.). Reference part determination means 14
Determines a logical object from the content elements selected on the screen of the document display means 17. That is, the reference component determining means 14 determines that the component is a reference component (step 101). The reference component determining means 14 moves up the logical objects one by one (step 102). The reference component judging means 14 checks whether or not there is a logical object on the top or whether or not the highest logical object is the root (step 103). Reference part judging means 1
If there is no logical object on the top and if the higher logical object is the root, 4 notifies the document editing means 18 that it is not a reference part (step 104).
The reference component judging means 14 checks whether or not there is reference component information in the logic object (step 105). When the reference component determining unit 14 determines that the reference component information is included in the logic object, the reference component determining unit 14 notifies the document editing unit 18 of the reference component (step 106). The document editing means 18 that has received the notification that it is a reference component performs a process of prohibiting editing on the reference component (step 10).
7).

FIG. 11 is a block diagram of the structured document processing apparatus according to the third embodiment of the present invention. The difference from the structured document processing apparatus having the logical structure shown in FIG. 1 is that the reference component information changing unit 111 changes the reference component information according to the instruction of the operator, and the reference component information changing unit 111 changes the reference component information. The reference component acquisition unit 15 that attempts to acquire the corresponding reference component corresponding to the above is further added.

FIG. 12 is a diagram for explaining a reference parts determination means capable of dynamically finding and changing a reference part and a document parts management database to be referred to in a third embodiment of the present invention. In FIG. 12, a document content display 121
Is a paragraph A, a document part 123 including a frame and the like, and a paragraph B.
And reference component information 128 of the document component. Further, the referenced document parts management database 70 stores graphic parts 123 ′, 124, table parts 125, various parts groups 126, and the like.

FIG. 13 is a diagram for explaining the reference part information added to the reference part in the third embodiment of the present invention. The reference part 123 has reference part information shown in FIG. 13, and is managed separately from the unique data group of the document part itself. For example, the reference part information 128 includes, for example, a server name 130 and a root category name 131.
, Category name 132, registration name 133, registrant name 134, registration date and time 135, and keyword information 136
The comment information 137, the component type 138, and the unique information 139 for each component type.

FIG. 14 is an explanatory diagram of a reference part information management sheet for dynamically updating the reference destination of a reference part according to the third embodiment of the present invention. In FIG. 14, a reference component information management sheet 140 is a sheet for managing reference component information, and is displayed on the document display means 17. Further, the reference part information management sheet includes a completion button 141, an apply button 142,
A cancel button 143, a reference destination change button 144,
The current status maintenance button 145 is provided, and there are a portion for displaying a server name and a root category name, and a portion for displaying a registered name, a registrant name, a registered date and time, a comment, and the like.

The user designates the "reference change" button among the display contents on the reference part information management sheet 140 displayed by the document display means 17. Then, the user can change the designation of the reference destination by setting the items in the area displayed below, for example, the server name, the root category name, the registration name, the registrant name, the registration date and time, and the comment. it can. By designating the reference destination and then designating the “Apply” button, the user provisionally sets the content in the document component area in the document. If the provisionally set content is desired, the reference destination of the content is reflected in the “reference component information” by designating the “completion” button.

FIG. 15 is a flow chart for explaining a processing example in the case of dynamically changing the reference destination in the third embodiment of the present invention. The user selects and designates the reference component in order to refer to the reference component during document editing. This indicates that the reference part in the document display means 17 is reversed and activated (step 151). The user gives an instruction to display the reference part information of the document part (step 1).
52). The reference part information of the document part is read (step 153). The reference component information management sheet management mechanism 112 is read by reading the reference component information of the document component.
Refers to the reference part information management sheet 140 by the document display means 17
(Step 154). The user specifies the server name while looking at the reference part information management sheet 140 (step 155). The reference component information management sheet management mechanism 112 checks whether or not there is a designated server name in the reference component information management sheet 140 (step 156).

Reference part information management sheet management mechanism 112
If there is a designated server, checks whether or not there is a designated root category (step 157). If there is no designated root category, the reference part information management sheet management mechanism 112 returns to the original, and if there is, displays the root category and below and selects a predetermined category / document part (step 158) Reference part information management The sheet management mechanism 112 displays the content. The user selects whether to display the contents (step 159). When the user selects the content display, the content of the designated document part is fetched and temporarily displayed at a predetermined place in the document (step 160). When the user sees the display and does not display the content in step 159, and when the content is provisionally displayed in step 160, the user checks whether or not the content of the reference part information management sheet 140 is desired (step 161). .
If the reference parts information management sheet 140 is desired,
If it is not the desired one, the process returns to step 158 and the selection is performed again.

As described above, since the reference component information management sheet 140 in which the reference component information is described can be displayed on the document display means 17 by the reference component information management sheet management mechanism 112, the user can dynamically change the reference component information. You can search and change it, and you can check the contents of the reference on the spot.
