Research on data processing in E-Learning Standard Test System

In order to solve the problem of different data formats in E-Learning Standard Test System, this paper translates each CELTS sub-standard from their own natural language format into XML schema document. The author writes out an independent XML parsing and validating package, which can automatically build up an internal data structure from each translated XML schema document. The author uses this private data structure to validate the XML data document. This innovation is applied in E-Learning standard test system successfully. It makes the whole test system more rigorous and maintainable.
