基于DTD的XML对照标记方法

XML Contrast Markup Method Based on DTD

基于DTD采用XML对照标记方法,对XML进行数字编码索引。这种索引方法考虑到了XML的半结构化的特点,研究了如何将XML文件与其DTD文件进行对照标记,利用DTD使XML文件的索引进行改进。使用这种方法可以实现了XML文件内容与结构的分离,将对结点标记的查询,统一转换到了对DTD的查询,节省了查询时间。

Using XML contrast markup method based on DTD, which is a numerical index to process the XML document. This index method considerate the XML character of semi - structured, it studies how to implement contrast makeup to XML and its DTD and improve the XML index by using DTD. With this method, it separates the content and structure to rewrite the XML document using numerical index. This method transform the operation of querying the tag to the operation of querying DTD, it can save the querying time.
