The Definition and Implementation of XML Document Update Language Based on Xquery
In order to fully evolve XML into a universal data representation and sharing format,we must allow users to specify updates to XML document and must develop techniques to process them efficiently. Update capabilities are important for modifying XML documents.The World Wide Web Consortium has developed a standard for XML query language,called XQuery,according to it,begin with defining XML document update granularity,design a XML update language XUL in this paper,propose a set of constructs for expressing six updating operations in both an ordered and unordered XML data model,and map this constructs into the syntax of the XQuery language.In the end,we provide a logical frame for implementing XUL within an XML repository based on a relational database system.
