主要还是弄清Nodelist和Node的关系。

 1 #include <iostream> 2 #include <tchar.h> 3  4 #import <msxml3.dll> 5  6 int _tmain(int argc, _TCHAR* argv[]) 7 { 8 CoInitialize(NULL); 9 //读取XML10 MSXML2::IXMLDOMDocumentPtr spXMLDoc;11 spXMLDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30));12 spXMLDoc->load(L"config.xml");13 MSXML2::IXMLDOMElementPtr spRoot = spXMLDoc->documentElement; //根节点14 15 //写入XML16 MSXML2::IXMLDOMNodePtr spNewNode = spRoot->selectSingleNode(L"/Win-DMS/SharedFolders")->appendChild(17 spXMLDoc->createNode(_variant_t(NODE_ELEMENT), L"Folder", L"")18 ); 19 spNewNode->text = L"D:\\123456\\";20 spXMLDoc->save(_variant_t(L"config.xml"));21 22 MSXML2::IXMLDOMNodeListPtr nolistptr = NULL;23 spNewNode->get_childNodes(&nolistptr);24 25 for (int i =0; i <nolistptr->Getlength(); i++)26 {27     MSXML2::IXMLDOMNodePtr nodeptr = NULL;28     nodeptr = nolistptr->Getitem(i);29     std::cout << "\tnodeValue: " << _bstr_t(nodeptr->nodeValue);30     std::cout << std::endl;31 }32 33 spNewNode.Release();34 //spNodeList.Release();35 spRoot.Release();36 spXMLDoc.Release();37 CoUninitialize();38 39 system("pause");40 return 0;41 }

判断是否有相同的元素，如果没有就加入到配置文件中去：

 1 　　　　 MSXML2::IXMLDOMDocumentPtr spXMLDoc; 2         spXMLDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30)); 3         spXMLDoc->load(L"config.xml"); 4         MSXML2::IXMLDOMElementPtr spRoot = spXMLDoc->documentElement;  5         MSXML2::IXMLDOMNodePtr spShareNode = spRoot->selectSingleNode(L"/Win-DMS/SharedFolders"); 6         MSXML2::IXMLDOMNodeListPtr FolderListPtr = NULL; 7         spShareNode->get_childNodes(&FolderListPtr); 8         MSXML2::IXMLDOMNodePtr FolderNodePtr = NULL; 9         long len = FolderListPtr->Getlength();10         for (int i =0; i <len; i++)11         {12             FolderNodePtr = FolderListPtr->Getitem(i);13             BSTR text = FolderNodePtr->Gettext();14             if(!lstrcmp((LPCWSTR)text ,szPath))15             {16                 isSaved = TRUE;17                 break;18                 //AfxMessageBox(L"该目录已经在列表中……");    19             }20         }21         if(isSaved == FALSE)22         {23             m_OwnerListBox->Add(szPath,  AfxGetApp()->LoadIcon(IDI_FOLDER));24             //读取XML25             MSXML2::IXMLDOMNodePtr spNewNode = spRoot->selectSingleNode(L"/Win-DMS/SharedFolders")->appendChild(26                 spXMLDoc->createNode(_variant_t(NODE_ELEMENT), L"Folder", L"")27                 ); 28             spNewNode->text = szPath;29             spXMLDoc->save(_variant_t(L"config.xml"));30 　　　　　}
