javascript problem

In the JavaScript below, there is a pseudo-code in comments. Can someone
help me translate the pseudo code to javascript code?
Please assist.

var oFilteredXML = new ActiveXObject( "Msxml2.DOMDocument.4.0" );
	var oTempXML = new ActiveXObject( "Msxml2.DOMDocument.4.0" );

	bSuccess = oFilteredXML.loadXML( "<calls></calls>" );

	var oRoot = oFilteredXML.firstChild;


	oTempXML = oCallsXML.selectNodes( sFilterString );

	oChildNode = oTempXML.nextNode;

	while( oChildNode != null )
	{
		oChildNewnode = oChildNode.cloneNode(true);

		//is oChildNode a DJ

			//is oChildNode's djDRID in oTempXML

				//do not append

			//else
				//append
			//end if
		//else
			//append
		//end
	    oRoot.appendChild( oChildNewnode );
		oChildNode = oTempXML.nextNode;
	}


	window.status = "Applying call stylesheet...";
	document.all.callDiv.innerHTML = oFilteredXML.documentElement.xml;
	document.all.callDiv.innerHTML = oFilteredXML.transformNode(
oCallsXSL.documentElement );
	window.status = "Done";
