//初始化：建立XML结构文件 ，创建根节点

TiXmlDocument *myDocument = new TiXmlDocument("ePhoto.xml");

       TiXmlDeclaration * decl = new TiXmlDeclaration( "1.0", "UTF-8", "" );

      myDocument->LinkEndChild(decl);

         TiXmlElement *ephoto=new TiXmlElement("ephoto");

      myDocument->LinkEndChild(ephoto);

       myDocument->SaveFile("ePhoto.xml");//保存

//打开已经建立的XML结构文件，对其进行操作。

TiXmlDocument *myDocument = new TiXmlDocument("ePhoto.xml");

myDocument->LoadFile();//载入文件

//增加节点

TiXmlElement *type1 = new TiXmlElement(type);//“type1”是字符串变量

TiXmlElement *type2 = new TiXmlElement("photo");

 type2->SetAttribute("ID","1");

myDocument->FirstChildElement()->LinkEndChild(type1); type1->LinkEndChild(type2);

//删除节点

TiXmlNode *node=first1;

myDocument->FirstChildElement()->RemoveChild(node);

//更新节点

TiXmlText te1(s);

xmlp->ReplaceChild(xmlp->FirstChild(),te1);

xmlp=xmlp->NextSiblingElement();

xml结构文件ePhoto.xml如下：

<?xml version="1.0" encoding="UTF-8" ?> <ephoto>     <Andy>         <photo ID="1">             <name>NULL</name>             <directory>NULL</directory>             <describe>NULL</describe>         </photo>     </Andy>     <Tom>         <photo ID="1">             <name>NULL</name>             <directory>NULL</directory>             <describe>NULL</describe>         </photo>     </Tom>     <Bill>         <photo ID="1">             <name>NULL</name>             <directory>NULL</directory>             <describe>NULL</describe>         </photo>     </Bill> </ephoto>
