摘要: 如何在XML流上高效地执行大量复杂XQuery查询是当今研究的热点之一。在数据选择分发等应用中,还希望在解析流的同时尽早地输出查询结果。为此,本文将XQuery查询的路径导航和结果构造两个阶段分别运行于服务器、客户机两端。导航阶段针对XQuery查询定义了扩展的基本XSIEQ机E-XSIEQ(Extended XML Stream Quervwith Immediate Evaluation),它是一种被索引化、基于栈的自动机。在EXSIEQ机上设计应用了TreeBuf(TreeBuffer)算法,它是一

Abstract: Much research has been done in evaluating massive complicated XQuery set over an XML stream efficiently. In some applications especially data selecting and distributing, it is further required to output the results while parsing XML stream for higher syst
