CMarkup XML CString

#include "Markup.h"
#include <iostream>
#include <string>
using namespace std;


int main()
{
CMarkup xml;
MCD_STR XML_Address = "UserInfo.xml";
MCD_STR XML_Head = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n";
MCD_STR XML_UserInfo = "UserInfo";
MCD_STR XML_UserID = "UserID";

//1.创建XML
/*MCD_STR XML_IDValue1 = "luo";
MCD_STR XML_IDValue2 = "lin";
xml.SetDoc(XML_Head);
xml.AddElem(XML_UserInfo);
xml.IntoElem();
xml.AddElem(XML_UserID,XML_IDValue1);
xml.AddElem(XML_UserID,XML_IDValue2);
xml.OutOfElem();
xml.Save(XML_Address);*/

//2.解析XML
string tagName;
string data;
xml.Load(XML_Address );
BOOL bFind = true;
xml.ResetMainPos();

while(xml.FindChildElem(XML_UserID))
{
//此时接点还是父接点
CString strTagName ;
CString strData ;
strTagName = xml.GetChildTagName();
strData = xml.GetChildData();

tagName = strTagName.GetBuffer(0);//此处出现问题
data = strData.GetBuffer(0);//此处出现问题
cout<<"tagName = "<<tagName<<",data = "<<data<<endl;
}

while(1);
return 0;
}
问题如下：
