linux tinyxml遍历

方法一、
bool ReadElemnt(string& szFileName)
{
 TiXmlDocument myDocument(szFileName);   
  bool loadOkay = myDocument.LoadFile();
  if(loadOkay == false)
   return false;
 TiXmlElement *rootElement = myDocument.RootElement();
 if(rootElement == NULL)
  return false;
 
 TiXmlElement *pItemElement = rootElement->FirstChildElement();
 TiXmlNode *pNextchild = pItemElement->ToElement();
 while(pNextchild)
 {
  pItemElement = pNextchild->ToElement();  
  
    TiXmlElement *NameElement = pItemElement->FirstChildElement();
    TiXmlElement *AgeElement = NameElement->NextSiblingElement();
    TiXmlAttribute *IDAttribute = pItemElement->FirstAttribute();       
    //输出第一个Person的name内容，即周星星；age内容，即20；ID属性，即1。     
  cout << NameElement->FirstChild()->Value() << "<br>";         
    cout << AgeElement->FirstChild()->Value() << "<br>";
    cout << IDAttribute->Value() << "<br>\n";
    
    pNextchild = pNextchild->NextSibling();
 }
 
 return true;
}
方法二、
void ParaseUpdateXml(TiXmlNode* pParent)
{
  if(pParent == NULL)
  return;        
  TiXmlNode* pChild = pParent->FirstChild();    
  while(pChild)
  {          
    cout << pChild->Value() << "<br>";
    int t = pChild->Type();
    if( t == TiXmlNode::ELEMENT)
