mfc 增删改 xml 节点

1、对xml的特定节点的属性的读取
MSXML::IXMLDOMNodePtr psNode;
MSXML::IXMLDOMNamedNodeMapPtr methodpAttrs = NULL;
MSXML::IXMLDOMNodePtr pmethodAttrItem;
try
{
if(SUCCEEDED(CoInitialize(NULL)))
{
if(SUCCEEDED(CoCreateInstance (MSXML::CLSID_DOMDocument,NULL,CLSCTX_INPROC_SERVER,MSXML::IID_IXMLDOMDocument,(void**)&pDoc)))
{

CComVariant vFile(path);//path为要读取的xml的路径
pDoc->load(vFile);
MSXML::IXMLDOMNodeListPtr pNodeList = NULL;
pNodeList = pDoc->selectNodes((_bstr_t)"xxxxxxxxxx"); //xxxxxxxxx处为要查找的节点
int num=pNodeList->Getlength();
for(int i=0;i<num;i++)
{
psNode=pNodeList->Getitem(i);
BSTR bstr=psNode->Gettext(); //取得psNode的节点值
。。。//进行相应的操作
psNode->get_attributes(&methodpAttrs);
methodpAttrs->get_length(&nCount);
for(int nmethod=0;nmethod<nCount;nmethod++) //属性值的循环
{
methodpAttrs->get_item(nmethod,&pmethodAttrItem);
CString strgetName =(char*)(_bstr_t)pmethodAttrItem->nodeName;
CString strgetValue=(char*)(_bstr_t)pmethodAttrItem->nodeTypedValue;
。。。//得到属性值后进行相应的操作
}

2、节点的删除
//首先找到相关节点

3、节点的建立
MSXML::IXMLDOMDocument* pDoc=NULL;
MSXML::IXMLDOMElementPtr pNode;

CComVariant vFile(path);
pDoc->load(vFile);
MSXML::IXMLDOMElementPtr pxmlRoot;
pxmlRoot=pDoc->documentElement;
int length=arr.GetSize();
pDoc->raw_createElement((_bstr_t)"nessus",&pNode); //建立nessus节点
pNode->setAttribute((_bstr_t)"id",(_bstr_t)arr.GetAt(0));

pDoc->raw_createElement((_bstr_t)"name",&psNode);//建立name节点
CString strname=arr.GetAt(1)+".nasl";
psNode->Puttext((_bstr_t)strname);
pNode->appendChild(psNode);
pDoc->raw_createElement((_bstr_t)"discription",&proNode); //建立discription节点
proNode->Puttext((_bstr_t)arr.GetAt(2));
