when responsetext comes back, -- name suggests -- text.

before can access html, have turn html.

this typed off cuff, like:

var tempdiv = document.createelement("div"); tmpdiv.innerhtml = request.responsetext; var wanteddiv = tmpdiv.queryselector('[id="cars"]'); // might want empty out 'partid' first document.getelementbyid('partid').appendchild(wanteddiv);
