A structured document inputted from a document input unit is decomposed into partial structures to be an editing unit in a document processing unit, and global structural information showing a relation between the partial structures is registered into a relational database. The decomposed partial structure is inputted to an editing unit processing unit, and information of elements as element information and a relation between elements in the partial structure as structural information are registered into the relational database. An ancestor-descendant relation between two elements can be determined easily and speedily by determining an ancestor-descendant relation between the partial structures of the global structural information and an ancestor-descendant relation of the structural information of the ancestor partial structure. |

DETAILED DESCRIPTION The present invention has been made in view of the above circumstances and provides a structured document management system and a structured document management method which can efficiently handle a large-scale structured document and can supply an environment in which plural persons can perform editing cooperatively.
In addition, the present invention provides a search device and a search method which can efficiently judge an ancestor-descendant relation between elements in a structured document managed by such a structured document management system and a structured document management method so as to search a document structure fast.
According to the present invention, in a structured document management system and a structured document management method for managing a structured document, an inputted structured document is decomposed into plural partial structures in accordance with a setting, and a relation between the partial structures is generated as first structural information.
A relation between elements in each of the decomposed partial structures is generated as second structural information, so that a depth-first node order is assigned to each of the elements in the partial structure, and a maximum node order of node orders of elements below the element is associated with the element.
The first structural information and the second structural information are retained and the structured document is managed.
In this manner, a structured document is decomposed into partial structures to retain the structures as first and second structural information.
Each of the partial structures is edited so as to limit the editing influence within the partial structure.
When plural persons edit the respective parts in charge at the same time, the influence on other partial structures can be eliminated.
In addition, the restructuring process can be performed fast because data restructuring may be performed only within the partial structure even when the structure is changed
