hi,all, I am trying to print out all the HTML DOM nodes from a page and save the result in a xml doc, here is my program:

<div style="color:Black;background-color:White; <pre>
<span style="color:Blue; void CHTMLBrowserDlg::ProcessHTMLDoc(MSHTML::IHTMLDocument2Ptr pDoc)
{
MSHTML::IHTMLDocument3Ptr pDoc3 = NULL;
MSHTML::IHTMLElementPtr pHtmlElem = NULL;
MSHTML::IHTMLElementPtr pElemBody = NULL;
MSXML2::IXMLDOMDocumentPtr pXMLDoc = NULL;
MSXML2::IXMLDOMElementPtr pHtmlXMLDomElem = NULL;
BSTR bstrTagName;
HRESULT hr;

hr = pDoc->QueryInterface(IID_IHTMLDocument3, (<span style="color:Blue; void**)&pDoc3);
<span style="color:Blue; if(SUCCEEDED(hr))
{
pHtmlElem = pDoc3->documentElement;
}

hr = pDoc->get_body(&pElemBody);
<span style="color:Blue; if(SUCCEEDED(hr))
{
HRESULT hr2 = pXMLDoc.CreateInstance(__uuidof(MSXML2::DOMDocument60), NULL, CLSCTX_INPROC_SERVER);
<span style="color:Blue; if(FAILED(hr2))
{
AfxMessageBox(L<span style="color:#A31515; "Failed to instantiate an XML DOM.");
<span style="color:Blue; return;
}

<span style="color:Blue; if(pHtmlElem->get_tagName(&bstrTagName) == S_OK)
{
pHtmlXMLDomElem = pXMLDoc->createElement(bstrTagName);
}

MSHTML::IHTMLDOMNodePtr pHTMLDOMNode =NULL;
MSHTML::IHTMLDOMNodePtr pHTMLBodyDOMNode =NULL;
MSXML2::IXMLDOMElementPtr pHtmlXmlDomElem = NULL;
BSTR bstrNodeName;

hr = pHtmlElem->QueryInterface(IID_IHTMLDOMNode,(<span style="color:Blue; void**)&pHTMLDOMNode);
<span style="color:Blue; if(hr == S_OK)
{
bstrNodeName = pHTMLDOMNode->nodeName;
pHtmlXmlDomElem = pXMLDoc->createElement(bstrNodeName);

hr = pElemBody->QueryInterface(IID_IHTMLDOMNode,(<span style="color:Blue; void**)&pHTMLBodyDOMNode);
<span style="color:Blue; if(hr == S_OK)
{
ProcessDomNodeSmartWrapper(pHTMLBodyDOMNode, pXMLDoc, pHtmlXmlDomElem);
}

pXMLDoc->appendChild(pHtmlXmlDomElem);

<span style="color:Blue; if(DOMDocSaveLocation(pXMLDoc))
AfxMessageBox(_T(<span style="color:#A31515; "XML DOM Document saved successfully"));
}
}
}
[/code]


<div style="color:Black;background-color:White; <pre>
<span style="color:Blue; void CHTMLBrowserDlg::ProcessDomNodeSmartWrapper(MSHTML::IHTMLDOMNodePtr pNode, MSXML2::IXMLDOMDocumentPtr pXMLDoc, MSXML2::IXMLDOMElementPtr pParentXMLDOMElem)
{
<span style="color:Blue; if(pNode->nodeType == 1)
{
MSXML2::IXMLDOMElementPtr pXMLElem = pXMLDoc->createElement(pNode->nodeName);

pParentXMLDOMElem->appendChild(pXMLElem);
MSHTML::IHTMLDOMChildrenCollectionPtr pChElemColl = MSHTML::IHTMLDOMChildrenCollectionPtr(pNode->childNodes);
<span style="color:Blue; long lLength = pChElemColl->length;
<span style="color:Blue; for(<span style="color:Blue; int i = 0; i < lLength; i++)
{
ProcessDomNodeSmartWrapper(MSHTML::IHTMLDOMNodePtr(pChElemColl->item(i)), pXMLDoc, pXMLElem);
}
}<span style="color:Blue; else <span style="color:Blue; if(pNode->nodeType == 3){
VARIANT varNodeVal;
HRESULT hr;

hr = pNode->get_nodeValue(&varNodeVal);
<span style="color:Blue; if(hr == S_OK)
{
pParentXMLDOMElem->text = (pNode->nodeValue).bstrVal;
}
}
}
[/code]
a sample html source is like this:

<div style="color:Black;background-color:White; <pre>

<span style="color:Blue; </<span style="color:#A31515; html<span style="color:Blue; >
[/code]

now the odd behaviour is that some nodes are not actually appended to the parent xml node when i walked down the html dom tree top-down, e.g. the first 3 children (input, script and script) of div element are missing in the result xml doc. so, whats
wrong with the code?
cheers
