1.首先从http://download.microsoft.com/download/b/7/1/b71d5305-618d-4b82-858b-386db3cc4453/msxml6.msi
下载msxml6安装包.

2.在Stdafx.h中引入库文件:#import <msxml6.dll>

3.在InitInstance中初始化ole.加入AfxOleInit()语句.

4."生成xml"按钮事件代码

UpdateData();MSXML2::IXMLDOMDocumentPtr pDoc; MSXML2::IXMLDOMElementPtr xmlRoot ; //创建DOMDocument对象 HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument60)); if(!SUCCEEDED(hr)) { MessageBox("无法创建DOMDocument对象，请检查是否安装了MS XML Parser 运行库!"); return ;} //根节点的名称为Book//创建元素并添加到文档中xmlRoot=pDoc->createElement((_bstr_t)"Book");//设置属性xmlRoot->setAttribute("id",(const char *)m_strId);pDoc->appendChild(xmlRoot);MSXML2::IXMLDOMElementPtr pNode;//添加“author”元素pNode=pDoc->createElement((_bstr_t)"Author");pNode->Puttext((_bstr_t)(const char *)m_strAuthor);xmlRoot->appendChild(pNode);//添加“Title”元素pNode=pDoc->createElement("Title");pNode->Puttext((const char *)m_strTitle);xmlRoot->appendChild(pNode);//保存到文件 //如果不存在就建立,存在就覆盖 pDoc->save("he.xml");

5."读取xml"按钮事件代码

MSXML2::IXMLDOMDocumentPtr pDoc;HRESULThr;hr=pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument60));if(FAILED(hr)){ MessageBox("无法创建DOMDocument对象，请检查是否安装了MS XML Parser 运行库!"); return ;} //加载文件 pDoc->load("he.xml"); MSXML2::IXMLDOMNodePtr pNode;//在树中查找名为Book的节点,"//"表示在任意一层查找 pNode=pDoc->selectSingleNode("//Book");MSXML2::DOMNodeType nodeType; //得到节点类型 pNode->get_nodeType(&nodeType); //节点名称 CString strName;strName=(char *)pNode->GetnodeName();//节点属性,放在链表中 MSXML2::IXMLDOMNamedNodeMapPtr pAttrMap=NULL;MSXML2::IXMLDOMNodePtrpAttrItem;_variant_tvariantValue;pNode->get_attributes(&pAttrMap);long count;count=pAttrMap->get_length(&count);pAttrMap->get_item(0,&pAttrItem);//取得节点的值pAttrItem->get_nodeTypedValue(&variantValue);m_strId=(char *)(_bstr_t)variantValue;UpdateData(FALSE);
