title: Parse XML from URL
body: <p>I'm trying to use Google Maps to calculate the distance between 2 points.I have the following url : </p>
  
  <p><code>http://maps.google.com/maps/api/directions/xml?language=fr&amp;origin="+parm1+"&amp;destination="+parm2+"&amp;sensor=false</code></p>
  
  <p>I'm quite a newbie in managing xml with x++ so how can I get the xml code returned by my url and parse it to extract the data I need (distance node values).</p>
