Research On VTD-XML Parsing Technique

With the continuous increase of the need for network application and enterprise decision-making support system, more and more applications need to visit various kinds of data sources and data connection. XML (Extensible Markup Language) as a solution to data exchange has its inborn advantages. XML includes a great deal of self-descriptive markers to accurately express various meanings of information; it provides abundant methods for data conformation and resolution; it can adapt to various and diverse network application environments and thus it is extensively applied in data exchange and interaction between different systems, which offers new carriers for information modeling, exchange and calculation. In order to quick parsing XML document, the research of XML parsing technique has become a hot topic for current research.This paper introduces the research tendency of XML parsing technique, and analyses the characteristic of DOM and SAX parsing technique of XML. Then focuses on VTD—XML parsing technique, and analyses the advantages and disadvantages of three parsing technique available. The VTD parsing technique not only increases the speed but also improves the performance of XML parsing. On the basis of that, this paper puts forward a promoting of VTD parsing technique, and designs a structural frame of the XML parsing system using Network Processor.
