Data From XML Not Displayed In IE

I am displaying some data from a XML sheet on my webpage. parsing it using javascript ofcourse. Now its working in all browsers except IE. I understand that IE handles xml different to other browsers and I've written that into my code. My issue is that the data I am trying to loop through is not the firstchild of my root node.

Javascript:
Code:
<script type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
} .....
