Semantic Search Based On XML Documents

This paper summarize theories and techniques of XML,and then put forward a semantic searching system base on XML documents.The main work of the system is:●Parse XML documents with DOM,and visit the DOM tree in the form of nodes with the arithmetic of depth search ,get datas which we need,then deal with the datas with the classes of nodes ,and storge the information of nodes into the table of database,and search in the index tables in SQL .●Put forward a blue print which can mark every nodes in document tree[3], make use of this blue print, we can find out ancestor nodes for every nodes quickly.●Put forward a new searching method based on XML documents,it contains the arithmetic of comparing the interconnection of every two nodes and a new method of comparing the interconnection of three or more nodes.Comparing interconnection of nodes is a method to represent semantic, it makes computer understand users'request better, so, search result can be more exact.
