First, the description contents of the document data stored in the storage unit 4 will be described with reference to FIG. Storage unit 4
As shown in FIG. 3, a set of “<>” consisting of “<” and the nearest “>” and a character string sandwiched between “<” and “>” in the document data stored in The tag is configured as “<character string>”. Among these tags, the start tag “<character string A>” and the end tag “</ character string A>” form a pair, and the position of the content between the start tag and the end tag is determined. Is defined as Also, “<title>” and “</ title>” are defined as title tags, and the content between the start tag “<title>” and the end tag “</ title>” is the title. Further, “<body>” and “</ body>” are defined as body tags, and the content between the start tag “<body>” and the end tag “</ body>” is the body. The definition of the above tag is X
It conforms to the ML (extensible Markup Language) standard.

For example, in the document data 10 of FIG.
The tag T1a “<chapter>” forms a pair with the tag T1b “</ chapter>” and indicates the position of the content of the first chapter sandwiched therebetween, and the tag T2a “<chapter>” and the tag T2b “<< chapter” ">" Indicates the position of the content of the second chapter sandwiched therebetween. Also, the tag T1-1a “<section>” and the tag T1-1b “<//
">" Indicates the position of the content of the first section and the first section sandwiched therebetween, and the tag T1-2a "<section>" and the tag T1-2
b “</ section>” indicates the position of the content of Chapter 1, section 2 sandwiched between them, and similarly, tag T2-1a “<section>” and tag T2-1b “</ section>” Indicates the position of the content of Chapter 2 Section 1 sandwiched.

In addition, the content “Chapter 1” sandwiched between title tags “<title>” and “</ title>” following the tag T1a
Is the title of the content of Chapter 1 sandwiched between the tags T1a and T1b, and the content “Description of Chapter 1” sandwiched between the body tags “<body>” and “</ body>” following the title tag This is the text corresponding to the title "Chapter 1". Similarly, tags T1-1a, T1-2a, T2a, T2-1a
Each content sandwiched between the title tags following the title is a tag T1.
-1a-b, T1-2a-b, T2a-b, T2
This is the title of the content sandwiched between -1a and -b, and the content sandwiched between the body tags following each title tag is the body corresponding to each title.

In the document data 10 shown in FIG.
In the contents of the first chapter indicated by a and b, the title tag following the tag T1a and the lower layer than the content indicated by the body tag following the title tag include T1-1a,
b and the contents of the first and second sections of Chapter 1 indicated by T1-2a and b are defined in the same layer, and in the content of the second chapter indicated by tags T2a and b,

First, when display of the document data 10 stored in the storage unit 4 is instructed from the input device of the input / output device 2, the display processing shown in FIG. 2 is started, and the table of contents generation processing unit 6 of the processing unit 5 transmits the document data. According to the ten tags, table of contents data is generated using the contents indicated by the title tags following each tag in order from the head tag T1a, that is, the title, and the table of contents data is generated in the table of contents area 101 of the display area of the display screen 100 shown in FIG. The table of contents data is displayed (step SP1). In addition, the text generation processing unit 7 sequentially uses the contents indicated by the text tags following the title tags, that is, the text, in order from the title tag following the head tag T1a of the document data 10, and executes
Text data for displaying text corresponding to each title displayed in 1 is generated and displayed in the text area 102 in FIG. The display screen shown in FIG. 4 is an initial screen for displaying a document, and the body area 102 displays all contents of the document data 10.

Next, when the title displayed in the table of contents area 101 is designated as a tag designation means from the input device of the input / output device 2 (the decision result in step SP2 is "YES").
), The table of contents generation processing unit 6 determines, based on the tag corresponding to the specified title, a title tag in a predetermined range indicated by the tag corresponding to the specified title among the title tags of the document data 10. Then, all the title tags following the tag of the same hierarchy and lower hierarchy as the tag are selected, and the selected title tag is notified to the text generation processing unit 7 to instruct generation of text data (step SP3). Next, the text generation processing unit 7 uses the content indicated by the title tag selected by the table of contents generation processing unit 6 and the content indicated by the text tag following the selected title tag to convert the text data. Generate and display in the body area (step SP
4).

For example, as shown in FIG.
0 displayed in the table-of-contents area 101 (underlined "1st
Is specified, the table of contents generation processing unit 6 sets the tag T1-1a of the document data 10 corresponding to the specified title.
Select the title tag that follows. In this example, there is no lower layer tag. Next, the text generation processing unit 7 uses the “section 1” indicated by the selected title tag and the “explanation of section 1” indicated by the text tag following the selected title tag to generate the text. The data is generated and displayed as shown in the text region 102 of FIG.

In the example of the display screen shown in FIG. 6, when a title displayed in the table of contents area 101 (underlined “Second Section”) is specified, the table of contents The title tag following the tag T1-2a of the corresponding document data 10 is selected, and the “second section” indicated by the selected title tag by the text generation processing unit 7 and the text tag following the selected title tag Are displayed as shown in the text region 102 from the "Description of the second section" indicated by.
