MSXL是Microsoft XML 分析器，是基于COM的，如果是在Windows平臺用起來比較方便。WM5.0也有MSXML，不用用法和其他Windows平臺下還是有些差異的。
首先要包含頭文件“Msxml2.h”，下面是代碼：
IXMLDOMDocument *pDoc = NULL;
 IXMLDOMNodeList *pNodelist = NULL;

 IXMLDOMNode *pNode = NULL;
 IXMLDOMElement *pRootElement = NULL;

 if(SUCCEEDED(CoInitializeEx(NULL,COINIT_MULTITHREADED)))//初始化COM組件
 {
  if(SUCCEEDED(CoCreateInstance(CLSID_DOMDocument,NULL,CLSCTX_INPROC_SERVER | CLSCTX_LOCAL_SERVER,IID_IXMLDOMDocument,(void**)&pDoc)))
  {
   VARIANT vFile;
   vFile.vt = VT_BSTR ;
   VARIANT_BOOL vBool;

   vFile.bstrVal = SysAllocString(FileName);//.XML文件名

   pDoc->load(vFile,&vBool);//加載XML文件
   if(vBool != VARIANT_TRUE)
    return ;
   /////////////////////////
   HRESULT hr; 
   hr = pDoc->get_documentElement(&pRootElement);
   if(SUCCEEDED(hr))
   {
    hr = pRootElement->QueryInterface(IID_IXMLDOMNode,(void**)&pNode);//獲取XML文件的根節點
    if(SUCCEEDED(hr))
    {
     BSTR bsxml;
     //解析XML文件，一層一層的解析
     pNode->hasChildNodes(&vBool);

     if(vBool == VARIANT_TRUE)
     {
      hr = pNode->get_nodeName(&bsxml);

      //獲取子節點的個數
      long value;
      pNode->get_childNodes(&pNodelist);
      pNode->Release();
      pNodelist->get_length(&value);

      for(int k = 0; k < value; ++ k)
      {
       BSTR bsxml1;
       pNodelist->get_item(k,&pNode);
       pNode->get_nodeName(&bsxml1);

       IXMLDOMNodeList *pSubNodelist = NULL;

       //獲取孫節點的個數
       pNode->get_childNodes(&pSubNodelist);
       pNode->Release();
       long leng;
       pSubNodelist->get_length(&leng);

       if (leng > 0)
       {

        IXMLDOMNode *pSubNode = NULL;

               //解析最下層的節點
        for(int i = 0; i < leng; ++i)
        {

         pSubNodelist->get_item(i,&pSubNode);
         pSubNode->get_nodeName(&bsxml);

  //判斷節點的屬性，如果是注釋屬性，則放棄
         DOMNodeType           ntValue;
        pSubNode->get_nodeType((&ntValue);
        if(NODE_COMMENT == ntValue)//也可以判斷其他的屬性，具體的查看MSDN
             continue;;
        

         //獲取節點的屬性個數
         IXMLDOMElement* pElement = (IXMLDOMElement*)pSubNode;
         IXMLDOMNamedNodeMap* pMap;
         pElement->get_attributes(&pMap);
         pSubNode->Release();

         long len;
         pMap->get_length(&len);

         //循環讀取節點的各個屬性（值和名字）
         for(int j = 0; j < len; ++j)
         {
         //如果還有下層的節點，繼續循環

          IXMLDOMNode* nameItem;
          VARIANT var;
          pMap->get_item(j,&nameItem);

          //獲取屬性名
          BSTR NAME;
          nameItem->get_nodeName(&NAME);

          //獲取屬性值
          nameItem->get_nodeValue(&var);
          LPWSTR VAL = var.bstrVal;

          int a = 9;

         }

        }
        pSubNodelist->Release();
       }
      }
      pNodelist->Release();
     }
     else
      pNode->Release();
    }
   }
   //////////////////////////
   pDoc->Release();
  }
  CoUninitialize();
