摘　　要：由W3C提出的XQuery语言业已成为处理XML的标准.通常XQuery只是查询XML的语言,但在XML作为后台数据的Web应用里,它也可作为服务器端脚本动态地生成网页,实现“XQuery+XML”模式的应用.因此,讨论用XQuery实现Session跟踪就很有必要.本文提出一种用XQuery构建Web应用的新技术,并通过在线购物的实例,提出一种跟踪Session的新方法:XML格式化Session.它采用XML文档作为用户的Session数据,用XQuery实现跟踪.结果表明,这一方法使得客户端和Web服务器能够进行有效的通讯.XQuery language has emerged as the W3C-proposed standard for processing XML. In general, XQuery is known as a language for querying XML, but it also is server-side scripting for dynamic web pages generation in an XML-backend application, that is to implement the Web application of “XQuery＋XML”. For this purpose, session tracking with XQuery becomes necessary. This paper proposes a new method to create a Web application using XQuery, and track a user＇s session by means of an example of on-line shopping. It proposes a new approach for session tracking： XML formatted session. Here XML documents are used as session files. XQuery works for trailing the session. As a result, the method can successfully attain efficient communication between clients and Web servers.
