一个基于MFC的XML封装类 CXml

一、源文件中包含有三个类（具体看头文件）：

  CXml      XML文件类
  CXmlNode  XML结点类
  CXmlNodes XML结点集合类  

using namespace std;

BOOL funDFS( CXmlNode & node );

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: 更改错误代码以符合您的需要
_tprintf(_T("致命错误: MFC 初始化失败\n"));
return 1;
}

CoInitialize(NULL);
{// 这个括号很重要 它限定了智能指针的生存套间 


CXml xml;
xml.Open( "I:\\VC_CXmlFile\\test.xml" );

//--------------------------------------------------------------------------


CXmlNode node1;
node1 =  xml.GetRoot()->GetChild("YEAR")->GetChild("MONTH")->GetChild("DAY");
cout << node1.GetName() << endl;



CXmlNode node2;
node2 = node1;
cout << node2.GetName() << endl;


CXmlNode node3( node2 );
cout << node2.GetName() << endl;


//////////////////////////////////////////////////////////////////////////
// 属性操作
cout << xml.GetRoot()->GetAttribute( "price" ) << endl;
