摘要
Based on idea of virtual Web page for the HTML page[6], this paper proposes firstly a concept of VXMLF(Virtual XML File), which separates the structure of XML file from the content of that. By means of modifying datamodel and query language of Xquery proposed by W3C, the paper gives an architecture of XQuery system based onvirtual XML. Comparing with the original system, this query system has many new characteristics and advantagessuch as simplifying memory process, easy to maintain consistency of data, optimization of query computation and sim-plifying user operation.
