Abstract: Taking the project research of CWPS as background, this paper proposes a design of XML parser based on blackboard structure pattern. Shortcomings of traditional compilers are analyzed. An architecture of XML parser is proposed to expound the architecture design theory. The key technologies of implementation are discussed, including the algorithm of building DOM tree, the object model of schema tree, the algorithm of availability validation and parsing engine. The architecture is feasible through the validation test and the results are satisfied.

Key words: XML parser, blackboard architecture, schema tree
