Liu Yuejun · Microcomputer Information · 2008
At present XML already became virtual standard of data in Internet and electronic. Two index technique, node record index and structure abstract index are researched. Besides, a thorough analysis of sector code technology is involved in this paper. Position of child node, parents'node and brother node in the Tree structure can get from the code values by using code technology. Because of the code technology, the dependency of node to tree structure is reduced. The introduction of index structure technology based Suffix Trees made nodes have same tag path merged as far as possible. So all the nodes in a tag path can obtained by a travels around of the tag path, it avoid the repeat visiting of the same tag path.
