Thanks Martin,

It took me a little while, but I finally managed to try what you suggested,
but it still ASSERTS.  I'm working with C++ smart pointers, and this is what
I tried.  If someone could suggest why the replaceChild asserts, that would
be very appreciated.  Essentially, I'm trying to replace a node with another
node that starts as a string.

HRESULT ParseSnippetIntoFrag( MSXML::IXMLDOMDocumentPtr spRoot, CString&
strNewXML,  MSXML::IXMLDOMDocumentFragmentPtr& spFragment )
{
  HRESULT hr = S_OK;
  CString CSValue;
  MSXML::IXMLDOMDocumentPtr spNewDoc = NULL;
  hr = spNewDoc.CreateInstance( XML_DOM_PROGID,   //
"Msxml2.DOMDocument.3.0"
                                                    NULL,
                                                    CLSCTX_INPROC_SERVER );
  ASSERT( SUCCEEDED( hr ) );
  spNewDoc->async = false;
  CSValue = _T( "<dummy>" ) + strNewXML + _T( "</dummy>" );
  if ( spNewDoc->loadXML( ( bstr_t )CSValue ) )
  {
    spFragment = spRoot->createDocumentFragment();
    ASSERT( spFragment != NULL );
    MSXML::IXMLDOMElementPtr spSubNodes = spNewDoc->documentElement;
    ASSERT( spSubNodes != NULL );
    while( spSubNodes->hasChildNodes() )
      spFragment->appendChild( spSubNodes->firstChild );
    TRACE( _T( "%s\n" ), ( LPCTSTR )spFragment->xml );
    return( S_OK );
  }
  return( E_FAIL );
}

And I call it by:

MSXML::IXMLDOMDocumentFragmentPtr spFragment = NULL;
MSXML::IXMLDOMNodePtr spParent = spAttrib->GetparentNode();
MSXML::IXMLDOMDocumentPtr spRoot = spParent->ownerDocument;

ParseSnippetIntoFrag( spRoot, CSValue, spFragment );
MSXML::IXMLDOMNodeListPtr spNodes = spRoot->getElementsByTagName( (
bstr_t )GetName() );
ASSERT( spNodes != NULL );
MSXML::IXMLDOMNodePtr spTargetNode = spNodes->item[ 0 ];
ASSERT( spTargetNode != NULL );
TRACE( _T( "new: %s\n" ), ( LPCTSTR )spFragment->xml );  // looks good
TRACE( _T( "old: %s\n" ), ( LPCTSTR )spTargetNode->xml ); // looks good
spRoot->documentElement->replaceChild( spFragment, spTargetNode );
TRACE( _T( "%s\n" ), ( LPCTSTR )spRoot->xml );

I see the proper new node and target node xml, so it appears the nodes are
correct, but the replaceChild gives me an E_INVALIDARG error.

Did I miss something in how I translated your JScript?

Thanks in Advance!
Corey.
