Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structured document processing system, and more particularly, to a structured document processing system by changing navigation data describing a structure conversion definition of a structured document and style data describing a document format definition. The present invention relates to a structured document processing system capable of generating a document in a desired format.

[0002]

2. Description of the Related Art An example of a conventional structured document processing system is described in Japanese Patent Application Laid-Open No. Hei 10-171809. The document processing system described in this publication designates that style conversion is to be performed on the conversion definition along with the style definition in the style data. The details are as follows. First, the conversion definition contains the original document,
There is a description about an external conversion process for generating a table of contents and an index generated by performing a structure conversion process, and an internal conversion process for combining a document obtained as a result of the external conversion process with an original document. Of these, the external conversion process specifies a call of an external program prepared in the system. Then, the document processing device that has read the style data first performs the structural conversion specified by the conversion definition, and combines the result and the original document into one document. Further, the combined document is laid out, displayed, and printed based on the style definition.

[0003]

However, the conventional structured document processing system merely considers displaying one structured document as one document.
There has been a problem that one document cannot be displayed as a plurality of related document groups linked by hyperlinks. In addition, since the structure conversion definition and the format definition are treated as one data, one or more structure conversion definitions and one or more format definitions cannot be specified and used in combination. There has been a problem that display and printing cannot be performed in a style suitable for the device.

Japanese Patent Application Laid-Open No. 9-153067 discloses a technique for tabulating hyperlink actions in a hypertext browser and customizing the operation (navigation) of the browser in context and table settings. ing. However, there is a problem that it is not possible to create a plurality of document groups having new hyperlinks and determine a navigation method of the documents.

Furthermore, Japanese Patent Application Laid-Open No. 9-305603 discloses a document creation method for controlling which content is included in each node of the document structure in creating a document sharing the logical structure and content of the document. . However, the relation between the document contents is expressed as a hierarchical structure of the output document, and there is a problem that it is not possible to have a relation between a plurality of generated documents.

Japanese Patent Application Laid-Open No. 10-49530 discloses a technique for generating an output schema from an input schema and a conversion rule. However, there is a problem that a plurality of output documents having hyperlinks cannot be handled merely by referring to a single output schema.

[0007] An object of the present invention is to allow a user to generate a plurality of related document groups linked by hyperlinks from an original structured document by describing navigation data for structural conversion and style data of style information. It is an object of the present invention to provide a structured document processing system capable of performing such operations. Another object of the present invention is to provide a structured document processing system capable of generating a document having a different document structure by various combinations of navigation data and style data and generating a document in a format suitable for a user's environment.
