从官网下载tinyxml源代码，加载其头文件tinyxml.h和库文件tinyxml.lib

xml内容如下

<xml version="1.0" standalone=no>
    <!-- Our to do list data -->
    <ToDo>
        <Item priority="1"> 
            Go to the 
            <bold>
                Toy store!
            </bold>
        </Item>
        <Item priority="2"> 
            Do bills
        </Item>
    </ToDo>
</xml>

代码如下：

TiXmlDocument doc("D:\\Temp\\demotest.xml");
    bool loadOkay = doc.LoadFile();

    if (loadOkay)
    {
        TiXmlElement* rootElememt = doc.RootElement();//根节点

        TiXmlAttribute* attributeValue = rootElememt->FirstAttribute();
        while (attributeValue)
        {
            //cout << attributeValue->Name() << ":" << attributeValue->Value() << endl;
            attributeValue = attributeValue->Next();
        }


        TiXmlElement* levelsElememt = rootElememt->FirstChildElement();//第一个子节点
        TiXmlElement* levelItem = levelsElememt->FirstChildElement();
        cout << levelItem->GetText();

        TiXmlAttribute* itemValue = levelItem->FirstAttribute();
        while (itemValue)
        {
            //cout << itemValue->Name() << ":" << itemValue->Value() << endl;
            itemValue = itemValue->Next();
        }

        TiXmlElement* levelBold = levelItem->FirstChildElement();
        cout << " " << levelBold->GetText();

        levelItem = levelItem->NextSiblingElement();//第二个子节点
        cout << " " << levelItem->GetText() << endl;;

    }

输出如下：
