Abstract

In this paper, we analyzed the present algorithms and models on transformation of XML document and other formal data, presented an approach based on DTD Element-Tree. In this approach, the Element-Tree was used to describe the structure of an XML document, and the structure mapping between the XML document and the other format data was built based on the Element-tree, which was used to complete the data transformation.The XWrapper was a transformation system on the XML document and the relational database data, which adopted the Element-Tree approach. The system generated the Element-Tree of a DTD, and used the mapping between XML document elements and columns in the database provided by the user to transform the XML document and data in the database based on the Element-tree.
