摘　　要：提出一种支持数据更新的XML压缩编码CXSU(A Compact XML storage for Supporting Update processing)。CXSU编码将节点路径信息进行分解,避免了记录重复信息,减小了编码长度;同时支持节点祖先后代关系、父子关系和兄弟关系的表示。实验表明CXSU编码能节省存储空间,有效的支持XML数据动态更新。The paper proposes a new approach( CXSU) that not only supports updating XML data,but also compresses the structure of an XML document. By decomposing path information,CXSU avoids recording repeated information,and reduces labeling length; moreover,CXSU supports the representation of ancestor-descendant relationship,parent-children relationship and sibling relationship between any two nodes. Experiments show that the effectiveness of CXSU supports the processing of XML data updating. Compared with other methods,the CXSU enjoys advantages in compact translated SQL and lesser relational database space.
