STRUCTURED DOCUMENT RETRIEVAL SYSTEM, METHOD FOR RETRIEVING STRUCTURED DOCUMENT AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire the data of a target node from a structured document database by freely transiting a parent's node, child's nodes or brother's nodes from a specified node in the structured document database.

SOLUTION: The structured document database (XMLDB) 11 stores structured documents. When a traverse request for specifying relative positional relation from an origin node which is an origin for retrieval is provided as a retrieval request, a traverse processing part 14 acquires data by tracing nodes from the origin node specified by the traverse request in accordance with the relative positional relation specified by the traverse request in the XMLDB 11.
