使用tinyxml插件来处理C++的xml读取和写入
读取和设置xml配置文件是最常用的操作，试用了几个C++的XML解析器，个人感觉TinyXML是使用起来最舒服的，因为它的API接口和Java的十分类似，面向对象性很好。TinyXML是一个开源的解析XML的解析库，能够用于C++，能够在Windows或Linux中编译。这个解析库的模型通过解析XML文件，然后在内存中生成DOM模型，从而让我们很方便的遍历这棵XML树。DOM模型即文档对象模型，是将整个文档分成多个元素（如书、章、节、段等），并利用树型结构表示这些元素之间的顺序关系以及嵌套包含关系。如下是一个XML片段：http://www.cnblogs.com/Images/OutliningIndicators/None.gif <Persons>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <Person ID="1">
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <name>周星星</name>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <age>20</age>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif </Person>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <Person ID="2">
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <name>白晶晶</name>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif <age>18</age>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif </Person>
http://www.cnblogs.com/Images/OutliningIndicators/None.gif </Persons>

在TinyXML中，根据XML的各种元素来定义了一些类：TiXmlBase：整个TinyXML模型的基类。TiXmlAttribute：对应于XML中的元素的属性。TiXmlNode：对应于DOM结构中的节点。TiXmlComment：对应于XML中的注释TiXmlDeclaration：对应于XML中的申明部分，即<？versiong="1.0" ?>。TiXmlDocument：对应于XML的整个文档。TiXmlElement：对应于XML的元素。TiXmlText：对应于XML的文字部分TiXmlUnknown：对应于XML的未知部分。 TiXmlHandler：定义了针对XML的一些操作。TinyXML是个解析库，主要由DOM模型类（TiXmlBase、TiXmlNode、TiXmlAttribute、TiXmlComment、TiXmlDeclaration、TiXmlElement、TiXmlText、TiXmlUnknown）和操作类（TiXmlHandler）构成。它由两个头文件（.h文件）和四个CPP文件（.cpp文件）构成，用的时候，只要将（tinyxml.h、tinystr.h、tinystr.cpp、tinyxml.cpp、tinyxmlerror.cpp、tinyxmlparser.cpp）导入工程就可以用它的东西了。如果需要，可以将它做成自己的DLL来调用。举个例子就可以说明一切。。。对应的XML文件：
