中文摘要：

提出一种XML建模技术,对多个XML文档构造共享模型.通过该模型构造的XML共享模式到关系模式的映射,实现将同源异构的XML片断抽取到相同的关系表中.试验表明,算法在同源异构XML片断的映射上具有比以往算法更好的映射结果.

英文摘要：

This article put forward an XML modeling method to build a shared XML model from the muti-XML document.The shared XML schema can be created by the shared model,and be mapped into the relational Schema to realize the mapping from the isomer XML document to the same relational database.The tests show that the algorithm in this article have better mapping result than other algorithm in isomer XML document＇s mapping.
