摘　　要：利用XPath路径表达式实现XML数据的分解,并提出建立一个XML数据完整性检查池来提供分解后的XML数据完整性检查.利用XPath表达式,在保持子文档有效性的同时易于实现XML文档的分解.利用建立的数据完整性检查池,用户可以检查所得数据的完整性,而不需要和其他用户的协作.该方法为细粒度安全环境中对XML文档的保护及发布提供了新的思路,为XML应用奠定了安全基础.The decompositon of XML document has a widely application in XML data security and XML document publishing. Two issues should be considered within XML document decomposition. First, each sub document should have a complete meaning. Second, a mechanism should be provided to check the integrity of decomposed results. The paper proposes an approach to decompose XML document using XPath expression, and further to construct an XML data integrity-checking pool to check the decomposed sub XML data. Utilizing XPath expression is easy to decompose XML data and keeps the original meaning of an XML subdata at the same time. User can check integrity of assigned data using XML data interity-checking pool without others supporting. The presented appraoch provides a new idea for XML data integrity protection within fine-grained security environment, and furter facilitates XML security development.
