基于扩展DOM树的XML SCHEMA文档转换为数据库模式算法

摘要

通过分析XML文档转换成数据库文件存在的问题,提出基于扩展DOM树的XML Schema文档转换为数据库模式的算法。提出了扩展DOM树的概念。描述了由XML Schema文档生成扩展DOM树算法。说明了路径键的概念及其作用。实现了将扩展DOM树转换成数据库模式的算法。实现过程使用了反向扫描优化和特殊元素处理规则。%By Analyze the problems of convert XML file document into Database,Proposed the algorithm of convert XML SCHEMA document into Database schema.Put forward the concept of extended DOM tree.Describes the algorithm of the expansion of DOM tree generated by XML Schema document.Illustrates the concept and the role of Path Key.Achieved the algorithm of convert Extended DOM tree into Database schema.In the implementation process,use the optimization of the reverse scan and the processing rules of special elements.
