Abstract:
PROBLEM TO BE SOLVED: To efficiently retrieve a portion conforming to a complicated retrieval condition in XPath.SOLUTION: An XML document retrieval device analyzes an XML document set to be retrieved, and generates both a sequence S for storing a shape of DOM tree based on structure information for the XML document and a sequence group T consisting of one or more sequences that store a type of structure path corresponding to each node of the DOM tree. Then, the device calculates a portion conforming to the structure path that is a retrieval query, by scanning the sequence S and the sequence group T.
