The Design And Realization Of Parser Sub-System In XML Parser Based On Schema Validation

As a markup language, XML(eXtensible Markup Language)will be the nextinternet standard of information exchanging for its capability of representing variouskind of data and interoperability through heterogenous applications.In order to recordor obtain the information and data in XML file in the information exchage, we need toparse and edit XML file,and XML parse is an important foundation in the XMLapplication.According to such technique and applied background, the author does the work ofthe design and realization of XML parser based on schema validation. Because thegroup divides the work, the author is responsible for the design and realization of theparser sub-system.The thesis analyze the requirement analysis of the XML parser,build up the basic frame and structure of the XML parser, study the various standardinterfaces of the XML parser and choose a suitable one as a base to design andrealization, and the thesis analyze, design and realize the XML parser and describe therealization of lexical analysis, syntax analysis and semantic analysis in detail.
