读出现有的XML文件，向根节点添加节点出错
MSXML2::IXMLDOMDocumentPtr spXMLDoc;
HRESULT hr;
CoInitialize(NULL);
hr = spXMLDoc.CreateInstance(__uuidof(DOMDocument));
if (FAILED(hr))
{
MessageBox(_T("无法创建DOM对象，检查是否安装了MS XML Parser运行库！"));
return;
}
spXMLDoc->load(CComVariant("F:\\KuoZhanTuKu.xml"));
MSXML2::IXMLDOMElementPtr spRoot = spXMLDoc->documentElement; //根节点
MSXML2::IXMLDOMElementPtr pe;
_bstr_t bstrtaaa(_T("aaa"));
pe = spXMLDoc->createElement(bstrtaaa);
spRoot->appendChild(pe);//调试到这句就会出错
spXMLDoc->save(CComVariant("F:\\kuozhan.xml"));
[解决办法]
F:\\kuozhan.xml
这个文件有错误
两个节点的反节点没有"/"号
