XPATH (XML PATH LANGUAGE) EVALUATION METHOD, XPATH EVALUATION DEVICE USING IT, AND INFORMATION PROCESSOR

摘要

PROBLEM TO BE SOLVED: To realize an analysis system and analysis method for evaluating XPath while streaming an XML document.

SOLUTION: This device comprises an XML parser 10 for inputting an XML event string constituting the XML document of a processing object, an XPath evaluation part 20 for executing the evaluation of XPath by streaming. The XPath evaluation part 20 successively evaluates the XPath for individual XML events transferred from the XML parser 10 and retains, when the XPath is partially established for a predetermined XML event, information relating to this partial evaluation result of XPath. When the last step of the XPath is established, it is evaluated that the XPath is established for the XML document.
