Abstract

According to the characteristics of the current XML query language,on XML data query language and query processing operations are analyzed in this basis,proposed a new XML database query language X-SQL,and trees in the query depends on the basis of designed XML data query processing method,the XML data query processing,path expression translation rules with the combination of XML data able to for the X-SQL query mapping into the appropriate SQL statements to obtain X-SQL the query results.
