The Three-dimensional Coding Based on the Cone for XML Under Weaving Multi-documents

ABSTRACT

In view of the deficiency of the XML document definitions extend the XML elements have to modify the original elements, under the multi-document analyzes the problem of low efficiency of the coding and the query when expand the node, this paper proposes the three-dimensional coding scheme applied to multi-document environment. The XML tree will be regarded as a cone, combining height, radian and marks to encode. Using the corresponding symbol to represent and using mathematical model to describe several new added marker elements, the coding method avoids the recoding of the node due to expansion of the XML document, improving the reusability of the document. The results show that, the method of definition improves the modularity and portability of the document definitions, compared with the existing coding methods, the three-dimensional coding has better performance and feasibility.
