Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus having a function of displaying and editing document data created by a word processor or the like on a screen. The present invention relates to a structured document editing method and apparatus for editing a structured document including a plurality of components having attribute information for specifying.

[0002]

2. Description of the Related Art In recent years, with the spread of the Internet,
As represented by an HTML document created in the TML language, a structured document including a plurality of constituent elements having attribute information for instructing a display content on a screen and a display mode on the screen is distributed. In such a structured document, attributes such as a character size, a color, and a layout method are specified for each component, and the content of the component is displayed on a screen according to the attribute value. If you try to enter additional characters with, it is necessary to specify the component to be edited. When specifying the component to be edited, if the component is nested, that is, if you specify multiple attributes such as bold, italic, and underline, each component occupies when displayed on the screen Since the regions are the same, it is difficult to specify only a component having the “bold” attribute, for example.

[0003] In an existing application for editing a structured document by the same editing operation method as a commonly used word processor or the like, a keyboard or a mouse is used to edit an object such as a character or a figure displayed on a screen. When the editing operation is executed after specifying the editing position with an input device such as, but the desired editing result is obtained on the display, but the structure of the component is not the expected result Are often seen. Therefore, as a means for identifying and editing components to be edited in structured documents, an editing device using an operation method different from a word processor etc. has been devised and actually used, but the method is generally as follows. It is like.

Method 1: Switching between the display mode and the edit mode. In the edit mode, a gap is inserted between the nested components so that a desired component can be specified. Method 2: An area for displaying the display data of the structured document and an area for displaying the structure of the structured document are independently allocated on the screen, and a desired component can be specified on the area for displaying the structure of the structured document. To do.

[0005]

However, in the above-mentioned method 1, the layout is different from that in the display mode by inserting a gap in the edit mode. Therefore, whether the layout is desired by the operator is determined. You must switch to the display mode after performing the editing operation on. In Method 2, unlike the method 1, it is not necessary to confirm the layout after the end of the editing operation. However, the operation of specifying the component to be edited in another area displayed independently is not familiar with the structured document. This operation is difficult for the operator to understand.

When a new entry is made as the content of a component, in both methods 1 and 2, (1) the component to be edited is specified, and (2) the content of the specified component to be edited is Separate operations, such as designating whether to newly input a position, are required, which is a complicated operation for an operator who is unfamiliar with the structured document. An object of the present invention is to provide a document editing apparatus capable of easily editing a structured document in view of such problems of the related art.

[0007]

According to the present invention, when a document is edited by a word processor, a text editor, or the like, which is widely used, the same operation as specifying a new input position with an input device such as a keyboard or a mouse is performed. By (edit position specifying operation), an operation of specifying a component to be edited and an operation of specifying a new input position in the specified component to be edited can be performed. By specifying the component to be edited by the same operation as specifying the basic editing position, if the component is nested,
By indicating that components are nested near the editing position, and by indicating that characters can be input at the position where each component exists, it is possible to intuitively identify the components to be edited. enable. By this means, while confirming the layout desired by the operator, it is possible to intuitively specify the component to be edited and specify the new input position only by a simple editing position specifying operation.

That is, the structured document editing method according to the present invention edits a structured document constituted by combining a plurality of components having display contents on a display screen and attribute information indicating a display mode on the display screen. In the structured document editing method, the input cursor indicating the input position is displayed on the display screen displaying the display contents of each component of the structured document reflecting its attribute information and selected as an edit target. An identification mark for specifying a display portion corresponding to the specified component is displayed. The identification mark is displayed, for example, by displaying a rectangular mark surrounding the display portion on the display portion, or by displaying the display portion itself by coloring or blinking, so as to be distinguishable from other display portions. Can be done by

When there are a plurality of components that can be selected as the object to be edited at the position where the input cursor is placed, the component to be edited can be selected by the same operation as moving the display position of the input cursor. When the operation of moving the input cursor display position to select the component to be edited is performed, the display position of the input cursor on the display screen does not change, and the display portion where the identification mark is displayed is selected. It is changed according to the change of the component.

When there are a plurality of selectable components to be edited at the position where the input cursor is placed, the attribute information of the selectable components is displayed, and the attribute information is displayed based on the displayed attribute information. Try to select the corresponding component. At this time, a sub-cursor whose display position moves by the same operation as moving the display position of the input cursor is displayed near the attribute information, and the component to be edited is selected by the sub-cursor. it can. Alternatively, it is also possible to display a number instead of the sub-cursor and make a selection with a number key or the like. The content of the editing operation at the input cursor position for the selected component, for example, the content of character input or deletion, is reflected on the document data of the structured document.

A structured document editing apparatus according to the present invention edits a structured document constituted by combining a plurality of components having display contents on a display screen and attribute information indicating a display mode on the display screen. A document structure recognition unit that recognizes the structure of each component from structured document data, a display content recognition unit that recognizes the display content of each component, and recognizes attribute information of each component. An attribute information recognizing unit, an input device for performing a document editing operation, an editing operation recognizing unit for recognizing an editing operation by the input device, and an editing target component from an operation regarding an input position by the input device recognized by the editing operation recognizing unit. An edit target component specifying unit to be specified, a document data update unit for updating the content of the document data based on the editing operation recognized by the edit operation recognition unit, a display content recognition unit and an attribute A display screen generating unit that generates display screen data based on information from the information recognition unit and the editing target component specifying unit; and a display device that displays the display screen data generated by the display screen generating unit. The display content of the component to be edited specified by the unit is marked and displayed on the display device, and when a plurality of components can be selected as the editing target at the input position displayed on the display device, input by the input device It is characterized in that the editing target component is changed by an operation relating to the position.
This structured document editing apparatus is capable of inputting the contents of each component forming the nested structure near the input position when selecting one of the components forming the nested structure as an editing target. Is displayed, and the component to be edited is changed by an operation related to the input position by the input device.

The sub-cursor 69 is displayed in a bold and italic part, and when input is performed in this state, it is notified that a bold and italic character will be input. At this time, the input position indicated by the cursor 68 (sub-cursor 69) corresponds to the position 69a in the document data shown in FIG. The position 69a in the document data is a position where the constituent elements are nested as </ U></I></B>, and the order of the font examples displayed in the pop-up screen 64 is the nested state. Reflecting, from the right, "Bold / Italic / Underline" attribute characters,
It changes like a character with the “bold / italic” attribute and a character with the “bold” attribute.

As described above, if the components are nested and it is not possible to completely specify the components to be edited simply by specifying the characters on the editing screen, the cursor position The display styles of characters and the like that can be input are shown by way of example, and one of the display styles is selected using a sub-cursor or the like. Therefore, even when the components have a deep nested structure, the operator can easily add, delete, etc. characters having desired attributes on the display screen.

FIG. 7 is a flowchart illustrating an example of an editing operation for editing a structured document on a display screen according to the present invention. In step 11 of FIG. 7, the document data reading unit 12 reads the document data from the auxiliary storage device 11. Next, in step 12, the document structure of the read document data is analyzed and recognized by the document structure recognition unit 13. This process is a process of analyzing and recognizing the hierarchical structure of the components. For example, the document data shown in FIG. 2 is described between <HTML> and </ HTML>, and it is recognized from this that this document is an HTML document. The content displayed on the screen is <B
ODY> and </ BODY>, and <B
ODY> It is recognized that the contents described before are not the contents to be displayed on the screen. Further, component 2 in FIG.
8, the components present inside are 28a-2
The four types of 8d are described stepwise from 28a to 28d, and the hierarchical structure is recognized.

Next, in step 13, the display contents are extracted from the document structure recognized by the display content recognition unit 14. In this processing, the tag indicating the attribute and the content to be actually displayed, that is, the characters described between the start tag and the end tag are separated. The separated display contents are displayed as shown in FIG. Next, in step 14, attribute information is extracted from the document structure recognized by the attribute information recognition unit 15. In this process, using the hierarchical structure of the components recognized in step 12, it is determined according to what attribute the display contents extracted in step 13 are displayed on the screen. For example, in the component 28 of FIG. 2, the characters "stop" are components 28a to 28d.
Therefore, it is determined that the display must be performed in the form of “paragraph, bold, italic, and underline” reflecting the respective attributes on the screen. On the other hand, the character "Remarks" is included in the component 28a, but not included in the components 28b to 28d, so that the display is determined to reflect only the attribute "paragraph".

Next, in step 15, the display contents are displayed on the display device 20 according to the extracted display contents and attribute information. In the next step 16, the editing operation is recognized in accordance with the information input from the input device 21 such as a keyboard. Specifically, it recognizes operations such as inputting, deleting, and copying characters, and operations for determining a position at which to execute those operations. Next, in step 17, when the information input from the input device 21 indicates a new input position designation, the edit target component specifying unit 16 specifies the cursor position, and specifies the component to be edited.

Next, at step 18, a mark is displayed on the component to be edited, and a cursor is displayed at the new input position. To specify a new input position, move the mouse cursor such as the arrow displayed on the screen with a pointing device such as a mouse to the position you want to edit, and press the pointing device button there or press the cursor movement key on the keyboard to input This is performed by moving the cursor to a position to be edited. Next, in step 19, the result edited according to the newly input data is reflected on the document data, and the document data is updated.
The updated data has its display contents recognized again in step 13, and the same processing is performed thereafter.

When a character is input from the input device 21,
First, the document data is updated in step 19, and then steps 13 to 18 are executed, and the changed result is displayed on the screen. Step 1 of the flowchart of FIG.
In steps 3 to 19, when the content of the editing operation is character input, all the processing in steps 13 to 19 is executed, and when the cursor is moved, the processing in steps 13 and 14 is omitted. here,
Referring to FIG. 8, in the structured document displayed on the screen as shown in FIG. 4, “:” is added after “date and time”, and bold “October 7” is changed to bold “Heisei 11”. October 7,
An example of a processing procedure when editing to be corrected on “day” will be described.

On the structured document display screen (edit screen), the cursor is placed on the line where paragraph 41 is displayed, and the cursor is moved from left to right by operating the cursor movement key of the input device 21. Then, as shown in FIG. 8A, a rectangular mark 82 is displayed around a portion where “date and time” is displayed, and “date and time” is displayed inside the rectangular mark 82.
Is displayed after the input cursor 81. FIG. 8A shows that the processing from step 11 to step 18 in FIG. 7 is performed on the document data shown in FIG.
In this state, the cursor is displayed at the end of the character "Remarks". In this state, when “date and time” is selected as an edit target and a character is input at the position of the input cursor 81,
This indicates that the input character has the same attribute as “date and time”.

FIG. 8B shows a state after the character ":" is input from the input device 21 to the input cursor position in FIG. 8A. After step 19 in FIG. 7 has been executed, the display device 20 of the document editing apparatus again executes the steps 13 to 18 to display the newly input character “:” in the character “ The date and time are displayed in the same font. The document data is updated as shown in FIG. 8E by step 19 in FIG.

Next, from the state shown in FIG.
When the operation of moving the input cursor by one step to the right by operating the cursor movement key of No. 1 does not move the position of the cursor 81, as shown in FIG. Only the display of the rectangular mark 83 is changed so as to surround the part “October 7”. Further, the input cursor 81 is also displayed inside the rectangular mark 83, and it can be seen at a glance that the character input at the position of the input cursor 81 is given the bold attribute similarly to the character "October 7". The new input data at this time is data indicating that "the cursor is moved to the right by one step".
It does not update the contents of the document data. for that reason,
After execution of step 19, the processing of steps 13 to 14 is omitted, and steps 16 to 1
8 is executed again, and the display is performed as shown in FIG.

In this state, when the character "1999" is newly input from the keyboard of the input device 21, the newly input character is changed to the rectangular mark through the step 19 in FIG. It is displayed in bold like the other characters in 84. First, in step 19 in FIG. 7, the data newly input by the document data updating unit 19 is added to the document structure, and the document data is updated. Next, the character "1"
The rectangular mark 83 indicating the component to be edited that surrounds only the part "0/07" is changed from step 13 to step 1
As a result of the execution of step 8, the character is enlarged by the newly input character, and becomes a rectangular mark 84 surrounding the entire part of "October 7, 1999". As shown in FIG. 8F, on the document data, the newly input character “1999” and the original character “October 7” are combined into one component having the same attribute. .

FIG. 9 is a flowchart for explaining another example of an editing operation for editing a structured document on a display screen according to the present invention. What is taken up here is an example of processing when the component to be edited has a nested structure. In steps 31 to 38 in FIG. 9, the same processes as those in steps 11 to 18 described in FIG. 7 are performed. Next, in step 39, when it is not possible to determine which component among the nested components is being selected only by displaying the selection mark and the cursor, an inputtable position corresponding to the component is displayed near the cursor. I do. The processing in step 40 is the same as step 1 in FIG.
9 is the same as the process in FIG.

Next, referring to FIGS. 10 to 12, FIG.
The screen displayed structured document as shown, "Remark
The details of the processing procedure for editing to change " Stop " to "Remark: this time unfortunately canceled in rain "("Unfortunately" is bold italic attribute, "rainy" is bold italic and underlined attribute) explain.
