一,建立一个基于对话框的程序,工程名为xml; 二, 初始化OLE. BOOL CXmlApp::InitInstance() { AfxOleInit(); ……. } 三, 在对话框中增加一个按钮,ID为IDC_CREATE,我们在这个按钮的响应函数中生成一个xml文件. void CXmlDlg::OnCreate() { MSXML2::IXMLDOMDocumentPtr pDoc; MSXML2::IXMLDOMElementPtr xmlRoot ; //创建DOMDocument对象 HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30)); 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!"); } //根节点的名称为china pDoc->raw_createElement((_bstr_t)(char*)"china", &xmlRoot); pDoc->raw_appendChild(xmlRoot, NULL); MSXML2::IXMLDOMElementPtr childNode ; pDoc->raw_createElement((_bstr_t)(char*)"City", &childNode); childNode->Puttext("WuHan");//节点值 childNode->setAttribute("population","8,000,000");//属性名,属性值 childNode->setAttribute("area","10000"); xmlRoot->appendChild(childNode); pDoc->raw_createElement((_bstr_t)(char*)"City", &childNode); childNode->Puttext("ShangHai"); childNode->setAttribute("population","12,000,000"); childNode->setAttribute("area","12000"); xmlRoot->appendChild(childNode); //保存到文件 //如果不存在就建立,存在就覆盖 pDoc->save("f://he.xml"); } 不要忘了#import "msxml4.dll" //引入类型库 四, 再增加一个按钮,ID为IDC_GET,在这个按钮的响应函数中读取xml文件. void CXmlDlg::OnGet() { //创建DOMDocument对象 MSXML2::IXMLDOMDocumentPtr pDoc; HRESULT hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30)); 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!"); } //加载文件 pDoc->load("f://he.xml"); //在树中查找名为City的节点,"//"表示在任意一层查找 MSXML2::IXMLDOMElementPtr childNode ; childNode = (MSXML2::IXMLDOMElementPtr)(pDoc->selectSingleNode("//City")); //得到节点类型 MSXML2::DOMNodeType nodeType; childNode->get_nodeType(&nodeType); //节点名称 BSTR var; CString name; childNode->get_nodeName(&var); name = (char*)(_bstr_t)var; //节点值 VARIANT varVal; childNode->get_nodeTypedValue(&varVal); CString strValue = (char*)(_bstr_t)varVal; //节点属性,放在链表中 MSXML2::IXMLDOMNamedNodeMapPtr pAttrs = NULL; MSXML2::IXMLDOMNodePtr pAttrItem; childNode->get_attributes(&pAttrs); long nCount ; pAttrs->get_length(&nCount); for(int i = 0 ; i < nCount ; i++) { pAttrs->get_item(i,&pAttrItem); //我们可以通过函数get_nodeName,get_nodeTypedValue得到属性名和属性值 //也可以直接得到 CString strAttrName = (char*)(_bstr_t)pAttrItem->nodeName; CString strAttrValue = (char*)(_bstr_t)pAttrItem->nodeTypedValue; } }
