One pointer:

YAHOO.html.clearChildNodes says effectively:

         if(nodeType != null && nodeType != 'undefined') {
             var remNodes = atNode.getElementsByTagName(nodeType);
         }
         else {
             var remNodes = atNode.childNodes;
         }
         var nodeLim = remNodes.length;
         for(var x = 0; x<nodeLim; x++) {
             atNode.removeChild(remNodes[0]);
         }
