摘要：

针对XML文档路径查询中无效扫描量大、分支路径连接操作复杂等问题，提出一种基于Schema的XML索引方法。通过Schema与查询路径匹配，确定需要扫描的XML文档。利用编码方法减少结点连接次数。实验结果表明，该方法较已有索引方法有更高的查询效率，具有较好的实用性及可扩展性。

关键词: XML文档, Schema模式, XML索引, 结点连接

Abstract:

To solve the problems of the cumbersome operation of node join and large ineffective scanning in XML path query, a new method of Schema-based XML index method is proposed. The XML is determined, which need to be scanned by matching Schema and query path. Code method is used to reduce the times of nodes connection. Experimental results demonstrate that this method achieves higher efficiency, better operability and expansibility than previous methods.

Key words: XML document, Schema mode, XML index, nodes connection
