General compressing technologies are not proper in some circumstances for the receivers are always required to decompress the data completely to manupulate the original data ( querying , validating etc . ) . the embedded document structure of xml also makes it difficult to perform access control because the traditional file level access control systems could not fulfill the requirement of element or attribute level access control . in the paper we first present a scheme for xml - based data exchange which is an xpath - query - friendly compressor for xml
压缩技术是提高交换效率的一种方法，但接收方需要对压缩文档完全解压才能够执行进一步的操作，在很多应用中这种方式并不适用，这就提出了如何在高效压缩的同时在压缩后的xml文档上进行查询等操作的问题；另一方面，由于xml文档的层次结构的特殊性，传统的文件级别的访问控制已经不能适应在元素、属性的级别上进行访问控制的需要，所以对只需要访问部分xml文档内容的用户进行有效的数据访问控制也是xml数据访问控制面临的一个问题。
