Design and implementation of GML parser based on grammatical and semantic database

This paper introduces the functional structure and framework of a universal GML schema-based parser. A valid algorithm for parsing various application schemas of GML is discussed in this paper. By making researches on intrinsic mechanism of core schemas, a set of grammatical and semantic parsing APIs are established to implement GML data parsing. The APIs would serve as the foundational operation collection for universal GML schema-based parsing engine.
