Abstract

(57) [Summary] [Purpose] To change the hierarchy of a structured document from the heading window expressed in the table of contents format, just like a table of contents. [Structure] When a structured document having a logical structure is edited, the logical structure of the document being edited is displayed in a table of contents by the index window display processing means 6, and a target instruction is given based on the display of the display means 8. A target heading is input from the input means 1, the target specifying means 2 specifies the target of the hierarchical position change in the logical structure by this input, and the change instruction input means 3 further specifies the contents of the hierarchical position change. , The hierarchical position changing means 4 changes based on the instruction of the contents of the specified hierarchical position change, and the logical structure matching processing means 5 performs the matching processing of the logical structure of the document according to the changing of the hierarchical position,
Based on this matching process, a heading window display process and a print image window display process are further performed to redisplay the hierarchy change result on the display means 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a word processor and a workstation, and particularly, means for displaying a document and a document structure in a format close to a printed result (hereinafter referred to as "WYSIWYG window").
And a means for extracting information based on the hierarchical structure of the document and displaying it as a table of contents (hereinafter referred to as "heading window")
The present invention relates to a document editing device having both of the above and a method thereof.

[0002]

2. Description of the Related Art Conventionally, it is sometimes desired to change the hierarchical structure of a document after creating a structured document having a logical structure. This hierarchical structure is changed while considering the overall structure of the document and the contents of the document. However, this is not a simple operation for the user.

Here, the conventional WYSIWYG format document creating apparatus attaches a mark to a character string to specify that it is a "heading" so that it can be extracted as a format and a table of contents for document allocation. However, it is not related to the logical hierarchical structure, and the headlines cannot be kept consistent. For example, there is a problem that "1.1.1" can be created without "1.1" under "1st chapter".

Further, an outline processor that creates a document after considering an approximate outline realizes a hierarchical operation with a tree structure. This tree structure is advantageous when performing hierarchical operations that are grouped in large units, and is convenient when visually understanding hierarchical relationships.

However, imagining the contents of the table of contents, it is not suitable for hierarchical operations such as "making chapter 1 into section 1.1".

Therefore, ISO8613 (Office Documen
There is an apparatus for creating a structured document that realizes document data management by holding both a hierarchical logical structure based on the t Architecture) and a hierarchical allocation structure (Japanese Patent Laid-Open No. 3-84661).
No. 4), and the screens of both the WYSIWYG window and the index window can be displayed and edited at the same time (Japanese Patent Laid-Open No. 4-111058).

However, in order to change the hierarchy of these things, a "tree chart screen" is used as an edit screen for the logical structure of a document, in which the units of the logical structure are boxes and the logical relationships are connected by lines. Even if this tree chart is directly displayed, there is a problem that the user still has difficulty intuitively grasping and operating the logical structure.

[0008]

As described above, in the conventional document editing apparatus for a structured document having a logical structure, when the hierarchy of the structured document is changed, the screen display displayed in the tree structure is used. However, there is a problem that this tree structure is not familiar to the user in general and is not suitable for a simple hierarchy change.

In view of the above, the present invention eliminates such a problem, and takes advantage of the advantage of treating as a logical block of a document displayed in a table of contents format, and also considers a print image.
Focusing on the characteristics of the heading window, which allows you to select and operate structured documents in logically organized units such as chapters and sections, change the hierarchy of structured documents without changing the order in which the document contents are displayed and printed. It is an object of the present invention to provide a document editing apparatus and method capable of automatically performing a table as if it were a table of contents.

[0010]

According to the present invention, in a document editing apparatus for editing a structured document having a logical structure, a display means and a table of contents window display processing for displaying the logical structure of the document being edited in a table of contents. Means, target instruction input means for receiving an input of the target instruction, target specifying means for specifying a target of hierarchical position change in the logical structure from the received input of the target instruction, and contents of the hierarchical position change in the logical structure Change instruction input means for receiving an instruction, hierarchical position changing means for changing the hierarchical position of the specified target on the logical structure based on the received content instruction, and a logical structure of the document according to the change of the hierarchical position. And a logical structure matching processing means for performing matching processing.

[0011]

According to the present invention, when a structured document having a logical structure is edited, the logical structure of the document being edited is displayed in a table of contents, and based on this display of the table of contents, an instruction to change the hierarchy is given. An input is made, the target of the hierarchical position change on the logical structure is specified by this instruction input, the contents of the hierarchical position change on the logical structure are further specified, and the hierarchical position of the specified target on the logical structure is described above. Change according to the instructions for changing the hierarchy position,
The logical structure of the document is matched according to the change of the hierarchical position, and the contents window of the structured document is displayed by displaying the contents window and the print image window based on the matching process. The hierarchy is changed automatically without changing the print appearance order.

The logical structure matching processing unit 5 performs the matching process of the logical structure of the structured document, and the heading window display processing unit 6 performs the displaying process of the heading window based on the matching process of the logical structure to display the display unit 8. The print image display processing means 7 performs print image display processing, and the display means 8 performs display output.

FIG. 2 is a block diagram showing the arrangement of a document editing apparatus which is an embodiment of the present invention. In FIG. 2, the input unit 1
Reference numeral 2 corresponds to the target instruction input means 1 and the change instruction input means of FIG. 1, and is constituted by a mouse or a keyboard.
The display unit 13 corresponds to the display unit 8 in FIG. 1 and is a display such as a CRT. The control unit 11 also includes a target specifying unit 2, a hierarchical position changing unit 4, a logical structure matching processing unit 5,
It corresponds to the heading window display processing means 6 and the print image display processing means 7, and the other input section 12 and display section 1
3. The overall control of the main storage unit 14, the auxiliary storage unit 15 and the like is also performed. When editing a document, the document editing program stored in the auxiliary storage unit 15 is read, and the document stored in the auxiliary storage unit 15 is read as necessary.

Here, an outline of the structure of a structured document will be described.

FIG. 3 is a diagram showing a document data holding structure of a structured document having a logical structure. As shown in FIG. 3, the document data has a double structure of a specific logical structure and a specific layout structure.
Manages one structured document. The specific logical structure is a structure in which a document is logically subdivided like chapters and sections, and the specific layout structure is a structure subdivided from a so-called layout. From this, it can be seen that the structured document shown in FIG. 3 is composed of two chapters if it is viewed as a specific logical structure, and if it is viewed as a specific layout structure, it has 2 pages of spreads, 3 pages in effect, and eventually 4 pages. You can see that it is composed of.

FIG. 4 is a diagram showing a layout result of the specific allocation structure shown in FIG. In FIG. 4, the sentences from content 1 to content 11 in FIG. 3, FIG. 1 and FIG. 2 are allocated to each page with an appropriate heading.

FIG. 5 is a diagram showing a display example of the index window. In FIG. 5, what is displayed is a part of the headline of a document in which the content of a certain invention is described, displayed as a table of contents. This is the heading window W
Called 1. On the other hand, the window W2 shows a specific layout structure of the same document, and WYSIWY showing a print image.
It is a G window and can be displayed at the same time as the index window W1. In the heading window W1,
For example, if you select "Select headline" which is the heading of 3, (iv), A, 2 the selected heading line will be reversed,
Display that it has been selected. Various editing can be performed on the selected heading line by a predetermined instruction.

Next, a hierarchical position change based on this heading window will be described with reference to a flowchart.

FIG. 6 is a hierarchy position change flowchart for changing the selected headline up one level.

In FIG. 6, when the headline is to be moved up one level, the object currently selected is first obtained,
Let this object be G (step 101). Then, G determines whether or not the heading portion has a tree structure (step 102), and if it does not have a tree structure, displays an error message (step 110), and ends this processing. On the other hand, if the tree structure is found in step 102, the hierarchical level of the G heading is obtained (step 1
03). Then, the hierarchy position changing means 4 changes this heading hierarchy level (step 104). This is to perform the process of subtracting 1 from the current level of G. Here, the value of the hierarchy level is incremented by 1 from the upper level to the lower level. For example, according to the tree structure, when the highest level is "1", the next lower level is "2" and the next lower level is "3". Next, the selection start position by changing the hierarchical position is set to G after the change (step 105). Furthermore, the selection end position by changing the hierarchical position is set to the end of the G subtree (step 106). Then, the selection information is set (step 107), and the logical structure matching processing means 5 performs the logical structure matching processing (step 108). Thereafter, the heading window display processing means 6 performs the processing, the print image display processing means 7 performs the processing, and the display means 8 redisplays (step 109). Then, this process ends.

FIG. 7 is a hierarchy position change flowchart for changing the selected headline one level down.

In FIG. 7, when the heading is to be moved down one hierarchy, first the object currently selected is obtained,
Let this object be G (step 201). Then, G determines whether the heading portion has a tree structure (step 202), and if it does not have a tree structure, displays an error message (step 210) and ends this processing. On the other hand, if the tree structure is found in step 202, the hierarchical level of the G heading is obtained (step 2
03). Then, the hierarchy position changing means 4 changes this heading hierarchy level (step 204). This is to perform the process of adding 1 from the current level of G. next,
G after changing the selection start position by changing the hierarchy position
(Step 205). Furthermore, the selection end position due to the hierarchical position change is set to the end of the G subtree (step 206). Then, this selection information is set (step 207), and the logical structure matching processing means 5 performs the matching processing of the logical structure (step 208). After that, the heading window display processing means 6 performs the processing, the print image display processing means 7 performs the processing, and the display means 8 re-displays (step 209). Then, this process ends.

FIG. 8 is a hierarchy position change flowchart for changing the selected headline to the hierarchy of the designated level.

In FIG. 8, when the headline is changed to the hierarchy of the designated level, the object currently selected is first obtained and this object is set to G (step 30).
1). Then, the G judges whether or not the heading portion has a tree structure (step 302), and if it does not have a tree structure, displays an error message (step 31).
0), this processing is ended. On the other hand, in step 302, if the tree structure is used, the hierarchical level of the G heading is obtained (step 303). Then, the hierarchy position changing means 4 changes the heading hierarchy level (step 30).
4). This is to change the current level of G to the specified level. Next, the selection start position by changing the hierarchical position is set to G after the change (step 305). Furthermore, the selection end position by changing the hierarchical position is set to the end of the G subtree (step 306). Then, this selection information is set (step 307), and the logical structure matching processing means 5 performs the logical structure matching processing (step 308). After that, the heading window display processing means 6 performs the processing, the print image display processing means 7 performs the processing, and the display means 8 redisplays (step 309). Then, this process ends.

Next, the result of the hierarchical position change from the designation of the hierarchical position change will be described with reference to a specific display example.

FIG. 9 is a diagram showing a state in which the heading row is selected. In the heading window W1 of FIG. 9, "3-
(Iv) -A-2 ", which is the heading" Select heading "
When the target instruction input means 1 is selected, the selected heading line is inverted and the selection is displayed on the window.

FIG. 10 is a diagram showing a state in which the heading row selected in FIG. 9 is changed to one level below. In FIG. 9, when the change instruction input means 3 gives an instruction of “downward by one layer” to the specified heading line, it is displayed in the heading window W1 of FIG. 10 according to the flowchart shown in FIG. The headline is changed to a new heading, and the hierarchy is changed to the next lower hierarchy. That is, the heading "Select heading" is the heading "3- (iv) -A-1-1.1".
The instruction to change the layer "down one layer" is realized by pressing the cursor key "→".

FIG. 11 is a diagram showing a state in which the heading row whose hierarchy has been changed in FIG. 10 is changed to one hierarchy higher. The heading “Select heading” whose hierarchy has been changed in FIG. 10 is set to 1 by the instruction “up one hierarchy” by the change instruction input means 3.
The hierarchy is changed on the hierarchy. That is, “select a headline” is a headline of “3- (iv) -A-2”. The instruction to change the layer to "up one layer" is realized by pressing the cursor key "←".

FIG. 12 is a diagram showing a state in which two heading rows are selected. In FIG. 12, first, when two heading lines of “select heading” and “instruct operation on one layer” are designated by the target designation input means 1, the target window display processing is performed by the target identification means 2. The specified headline is highlighted on the window W1 of the display means 8 via the means 6.

FIG. 13 is a diagram showing a state in which the two heading lines selected in FIG. 12 are changed to one level higher. In FIG. 13, when the change instruction input unit 2 instructs "upward one level" to the two heading lines highlighted in FIG. The hierarchy is changed on the hierarchy. That is, as shown in FIG. 12, “3- (iv) -B” “select heading row”.
And "3- (iv) -B-1" has a heading line of "instruct operation on one layer", "3- (v)" has "select a heading line", and "3- ( v) -A ”is changed to“ Instruct operations one level higher ”.

FIG. 14 is a diagram showing a state in which the two heading lines shown in FIG. 13 are further changed one level higher. In FIG. 13, if the two heading lines changed to one layer higher are further instructed to change the layer to "up one layer",
"3- (v)""Select heading line" and "3- (v)"
"(V) -A""Instruct operation to one level higher"
The hierarchy is changed to “select headline row” of “4” and “instruct operation to one hierarchy” of “4- (i)”. With this hierarchy change, "4""drawingdescription" is "5"
It is corrected to the heading of "Description of Drawings".

In this way, by selecting the heading line displayed in the heading window and instructing the hierarchy change, the selected heading line can be displayed without changing the appearance order in the display printing of the contents of the document. You can change the hierarchy.

However, changing the hierarchy level does not create a new heading. Therefore, it is not possible to make changes that jump over the logical level.

Further, the hierarchy level change is irreversible, and once "up one level" is executed, the heading of the next page is absorbed, and immediately after "down one level" is executed, the original level is changed. It does not return to a hierarchical relationship. To return to the original state, it is necessary to select the absorbed headline of the next page and change the hierarchy separately.

Now, a general hierarchy change will be described.

First, FIG. 15 is a diagram for explaining the tree structure, and FIG. 16 is a diagram for explaining the order of the tree structure. FIG. 15 shows an example of a general tree structure. In the case of the tree structure as shown in FIG. 15, when the object of the current d is considered as a center, there is a parent a and a younger brother b of the parent one level higher. , The elder brother c and the younger brother e are at the same hierarchical level as the object of the current d, and the eldest son g and the youngest child h connected to the current d are at a level one hierarchy below the object of the current d, and the tree structure of the elder brother c. There is the youngest brother f underneath. In this way, in the case of the tree structure, it is explained using a special term depending on its connection relationship.

In the case of the tree structure as shown in FIG. 16, the numerical values of the numbers shown are in the order of the objects.
Therefore, for example, the “front” of the object T1 (8) becomes the object T2 (7).

Now, FIG. 17 is a general flowchart for changing the hierarchy by the heading window. In FIG. 16, when changing the current object to a new level of the heading hierarchy, first, the parental heading structure of the current object is obtained, and the level of this parent is set to A (step 401). And
It is determined whether or not the new level to be changed is equal to or lower than the level of A (step 402). If the new level is equal to or lower than the level of A, it is further determined whether or not the new level is lower than the highest level ( (Step 403) If it is not lower than the highest level, move to Step 404 and perform processing to raise the hierarchy to the upper level. If it is lower than the highest level, an error message is displayed (Step 416) and this processing is terminated. .

On the other hand, if the new level to be changed is not lower than the level of A in step 402, it is judged whether or not the level obtained by adding "1" to the level of A is smaller than the new level (step 421). If the level is smaller than the level, a message indicating that hierarchy change is not necessary is displayed and this processing ends. On the other hand, if it is not smaller than the new level in step 421, it is further determined whether or not the current object has an older brother. If there is no older brother, an error message is displayed (step 432) and this processing ends. Meanwhile, step 422
When there is an older brother, the process proceeds to step 423, and the process of lowering the hierarchy is performed.

First, the process of raising the layers after step 404 will be described. First, it is judged whether or not the new level is equal to the A level (step 404), and if not, the parental heading of A is obtained, this parental heading is set to A (step 405), and this A is found. It is judged whether or not it is not present (step 406), and if it is not found, the present process is terminated, and if found, the process proceeds to step 404 and is repeated. In step 404,
If the new level and the level of A become equal, the new level is subtracted from the level of the current object, and the value is used as the number of times (step 407). Further, a younger brother object of the current object is obtained and set as B (step 40).
8). Then, the parent of B is obtained, and the object is set as C (step 409). Further, B is reconnected to the youngest child of the current object (step 410), and the object C is set to B (step 411). Then, it is determined whether or not the object B exists (step 412). If the object B exists, the process returns to step 409 and the process is repeated. On the other hand, if B does not exist in step 412, the current object is connected to the parent's younger brother (step 4
13) Then, "1" is subtracted from the current number and the value is set as the number of times (step 414). Then, it is judged whether or not the number of times is "0", and if the number of times is not "0", step 40
8, the process is repeated until the number of times reaches “0”. On the other hand, if the number of times becomes “0” in step 415, this processing is ended.

Next, the process of lowering the hierarchy after step 423 will be described. First, the "previous" heading structure of the current object is obtained, and that object is set to A (step 423). Then, it is judged whether or not the new level is equal to the level of A (step 424), and if they are not equal, the “previous” heading of A is obtained and this object is replaced with A (step 425). It is judged whether or not it was not found (step 426). If A is not found, an error message is displayed (step 4
32), the present process is terminated. On the other hand, if A is found in step 426, the process proceeds to step 424 and the above processing is repeated. In step 424, if the new level is equal to the level of A, the level of the current object is subtracted from the new level, and this value is set as the number of times (step 427). Then, the current object is connected to the youngest child of the older brother object (step 428),
"1" is subtracted from the current number, and the value is set as a new number (step 429). Further, it is determined whether or not this number is "0" (step 430). If the number is not "0", the process proceeds to step 428 and the process is repeated. on the other hand,
In step 430, when the number of times becomes “0”, this processing ends.

By performing such processing, general hierarchy changing processing becomes possible. Besides, The hierarchy can be changed up and down without changing the order of appearance of the contents of the target document in display printing.

[0044]

As described above, according to the present invention, when a structured document having a logical structure is edited, the logical structure of the document being edited is displayed in a table of contents, and the display of the table of contents is used as a basis. Input the instruction of the target to change the hierarchy, specify the target of the hierarchical position change in the logical structure by this instruction input, and
Instructing the contents of the hierarchical position change on the logical structure, changing the specified hierarchical position of the logical structure on the basis of the instruction of the contents of the hierarchical position change, and changing the logical position of the document according to the change of the hierarchical position. A structure matching process is performed, and based on this matching process, a table-of-contents window display process and a print image window display process are performed and displayed on the display means.

That is, in the table of contents format, the structured document is a chapter,
Since the hierarchy can be changed by paying attention to the characteristic of the heading window that can be selected and operated in a logically organized unit called a section, it is possible to automatically change the hierarchy of a structured document as if it were a table of contents. This has the advantage that it can be performed and the appearance order of display printing of document contents is not changed.
