I should have been more specific, I've attached my asp code below but it displays nothing. Any ideas? I have also attached a sample XML doc
<html>
<body>

<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");
  }
xmlhttp.open("GET","depots.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML; 

document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName("depots");
for (i=0;i<x.length;i++)
  { 
  document.write("<tr><td>");
  document.write(x[i].getElementsByTagName("Depot")[0].childNodes[0].nodeValue);
  document.write("</td><td>");
  'document.write(x[i].getElementsByTagName("Depot")[0].childNodes[0].nodeValue);
  'document.write("</td></tr>");
  }
document.write("</table>");
</script>

</body>
</html>

Open in new window

malformed XML

<?xml version="1.0"?>

<depots>

	<depot="Aberdeen">
		<address="some address"/>
	</depot>
</depots>

Open in new window



"corrected" :
<?xml version="1.0"?>

No I want to read it from the XML. There are lots more elements and values within my full xml, didn't want to publish full depot info online.

If I can get this start point working I can build from that
