Abstract: The dissertation analyzes the traditional DOM and SAX parsing technology and points out their defects: DOM easy to use but there is a high memory consumption; SAX memory consumption is low but it is difficult to pay a return visit. The dissertation utilizes VTD-XML technology supporting for XPath and provides a schedule of parsing process definition file. Experiment results show that the method improves the parsing efficiency， reduces the memory consumption.

Key words: document management system, VTD-XML, workflow
