Hello,

I am having problems trying to get a field from a XML file.

I can load the XML file into my browser and display it as a string but have looked everywhere and can't seem to get a value from the XML file.

I need to be able to do this client-side (no server-side scripting)

I am trying to display the current temp etc as a variable
<w:current temperature="13.5" dewPoint="8.5" humidity="72" windSpeed="7.4" windGusts="9.3" windDirection="WSW" pressure="1019.9" rain="1.6" />


My JavaScript code looks like the following:
Code:
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",data,false);
 xmlhttp.send();
 xmlDoc=xmlhttp.responseXML;
 
 alert(xmlDoc.getElementsByTagName("w:current")[0].childNodes[0].nodeValue);
My XML file:

Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
