Abstract

A streaming query system for extensible markup language is provided. An XPath query translator receives and analyzes a user-input XPath document. An abstract syntax tree analyzer establishes an abstract syntax tree. A XML parser receives and parses an XML document. An index generator generates an index for the XML document. A computation module performs a format calculation based on the abstract syntax tree and the index, and generates a query result accordingly.
