说明：  timyXML是一个简单的xml解析工具，当然，你的xml必需是标准的。 TinyXML is a simple, small, C++ XML parser that can be easily integrated into other programs.In brief, TinyXML parses an XML document, and builds from that a Document Object Model (DOM) that can be read, modified, and saved. XML stands for "eXtensible Markup Language." It allows you to create your own document markups. Where HTML does a very good job of marking documents for browsers, XML allows you to define any kind of document markup, for example a document that describes a "to do" list for an organizer application. XML is a very structured and convenient format. All those random file formats created to store application data can all be replaced with XML. One parser for everything.(timyXML is a simple xml analytical tools, of course, you must be the xml standard.
