XML query approach based on logic XML tree
一种基于树状逻辑式的XML查询方法

With the wide application of XML in data representation and exchange, the query approach to XML document becomes a key problem in current data processing. Some studies such as XPath and XQuery had been adopted and applied, however, these works were still to be improved in query presentation.Following the idea of pattern matching,this paper designed a new logic tree expression called LXT which could present the XML query in a tree pattern. Further,discussed the XML approach to query XML document based on LXT expressions, including the features of filtering and constructing the query result,which illustrated the ideas of designing the XML query language with LXT.
