To effectively solve poor efficiency update problem owing to recoding when update operation is done and resolve overflow problem because of insufficient reserve space when excess nodes are inserted.By analyzing the relevant reasons for poor efficiency,a XML coding scheme is presented,which supports update operation.When XML update operations are executed,recoding is avoided and space costs are reduced with the coding scheme.The corresponding table is adopted to replace the dot separator of each layer,then the length of coding is shorten accordingly.Based on the coding scheme,the XPath query method is proposed and the structural relation of nodes can be judged quickly.Theoretical analysis and experimental results show the accuracy and efficiency of the proposed coding scheme.
