Including the advantage of XML, the essential of XML, XML document structure, the principle of XML Parser and the syntax of Regular Expression. 介绍了XML的优势以及XML的几个要素,XML文档的结构,XML解析器的原理以及正则表达式的语法。
Node index is one of the most representative XML indexes and can support regular path expression, but for the long query path expression, especially when the intermediate results are many, the joint operation of the intermediate results is time consuming. 节点索引是XML索引中可支持正则路径表达式的最具代表性的一种,但是对于长的查询路径表达式,尤其是在中间结果很多的时候,节点索引的连接操作代价很高。
Research and Implementation for XML Query Optimization Technology Based on Regular Path Expression 基于正则路径表达式的XML查询优化技术的研究与实现
The validator framework based on struts is a mechanism configuring outside XML files with the reusable validation regulations and matching regulations of regular expression. 基于Struts的数据校验框架是一种通过配置外部XML文件,是一种利用可重用的校验规则和正则表达式匹配规则的校验机制。
The rule and type system changes discussed in the previous section must be applied to the XML rule and type system files in the installed version of the regular expression annotator PEAR. 对于安装的正则表达式注释器PEAR版本中的XML规则和类型系统文件,必须应用上一节讨论的规则和类型系统修改。
