How do I ignore comments in XML Checkpoints?

It's unfortunate that this scenario is not handled by TestComplete :(

I did some reasearch and ended up using the following code, which seems to be working. It returns the given XML doc with comment nodes removed. 

var Node =
    {
      ELEMENT_NODE                :  1,
      ATTRIBUTE_NODE              :  2,
      TEXT_NODE                   :  3,
      CDATA_SECTION_NODE          :  4,
      ENTITY_REFERENCE_NODE       :  5,
      ENTITY_NODE                 :  6,
      PROCESSING_INSTRUCTION_NODE :  7,
      COMMENT_NODE                :  8,
      DOCUMENT_NODE               :  9,
      DOCUMENT_TYPE_NODE          : 10,
      DOCUMENT_FRAGMENT_NODE      : 11,
      NOTATION_NODE               : 12
    };

function getXMLDocWithoutComments(givenXMLFullPath)
{
 var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
  var objNodeList;
  xmlDoc.async = false;
  xmlDoc.load(givenXMLFullPath);
  if (xmlDoc.parseError.errorCode != 0) {
     var myErr = xmlDoc.parseError;
  } else {
    objNodeList = xmlDoc.childNodes;
     for (var i=0; i<objNodeList.length; i++) {
        if(objNodeList.item(i).nodeType == Node.COMMENT_NODE)
        {
            xmlDoc.removeChild( objNodeList.item(i) );
        }
     }
  }
  return xmlDoc;
}
