With the development of network technology,the XML age is comingBecause the XML document is just a text file,if the information in the XML document is to be adequately used,XML document has need consequently to be parsedThis paper firstly introduces the DOM(Document Object Model) parsing and the SAX(Simple API for XML) parsing,then introduces that how to pasrse the XML document by Libxml2

GML data is widely used for model building, data exchanging, etc. The GML data parsing is the base of handling other
operation of GML. The parsing technology of XML can be used for GML parsing. But the XML parsing technology is
deficient in parsing semantic information on geography information. This paper tries to build a semantic information
database (SIDB) of GML and design GML core schema-based parsing engine which based on SIDB. Ultimately
actualize GML data parsing. The results of the study are verified by GML test data in the paper. And more, this study
provides a new way to parsing semantic information in other fields.

The semantic parsing for GML based on SIDB

In the information times, as the carrier of data storage and transmission, XML is widely used because of its cross-platform and scalability. The reading of XML documents requires the use of parsers to extract the data information and the hierarchical structure, and check its validity. This paper presents an XML document parsing model based on DOM and SAX technology. Through experiments, the performance of DOM and SAX parsers is analyzed and compared.
