C++生成和解析XML文件的讲解

 TiXmlDocument xmlDocument;
 // 添加XML声明
 xmlDocument.LinkEndChild(new TiXmlDeclaration( "1.0", "GBK", "" ));
 // 添加根元素
 TiXmlElement * xmlRoot = new TiXmlElement("root");
 xmlDocument.LinkEndChild(xmlRoot);
 //根元素下添加子元素1
 TiXmlElement* xmlChild1 = new TiXmlElement("name");
 xmlRoot->LinkEndChild(xmlChild1);
 xmlChild1->LinkEndChild(new TiXmlText("woniu"));
 xmlChild1->SetAttribute("id", "0001");//设置属性
 //根元素下添加子元素2
 TiXmlElement* xmlChild2 = new TiXmlElement("Student");
 xmlRoot->LinkEndChild(xmlChild2);
 TiXmlElement* xmlChild2_01 = new TiXmlElement("name");
 xmlChild2->LinkEndChild(xmlChild2_01);
 xmlChild2_01->LinkEndChild(new TiXmlText("woniu201"));
 TiXmlElement* xmlChild2_02 = new TiXmlElement("classes");
 xmlChild2->LinkEndChild(xmlChild2_02);
 xmlChild2_02->LinkEndChild(new TiXmlText("86"));
 //保存xml文件
 xmlDocument.SaveFile("woniu.xml");

 TiXmlDocument xmlDocument;
 if (!xmlDocument.LoadFile("woniu.xml"))
 {
 return -1;
 }
 //根节点
 TiXmlElement* xmlRoot = xmlDocument.RootElement();
 if (xmlRoot == NULL)
 {
 return -1;
 }
 //获取子节点信息1
 TiXmlElement* xmlNode1Name = xmlRoot->FirstChildElement("name");
 const char* node1Name = xmlNode1Name->GetText();
 const char* node1AttId = xmlNode1Name->Attribute("id");
 //获取子节点信息2
 TiXmlElement* xmlNode2Stu = xmlRoot->FirstChildElement("Student");
 TiXmlElement* xmlNode2_name = xmlNode2Stu->FirstChildElement("name");
 TiXmlElement* xmlname2_classes = xmlNode2Stu->FirstChildElement("classes");
 const char* node2Name = xmlNode2_name->GetText();
 const char* node2Classes = xmlname2_classes->GetText();
