ActionScript 3 - XML - NavigateToURL

Question

Ok there are many tutorials out there on how to use this function, what I am trying to do and can't seem to find a tutorial on is using navigateToURL with the "mailto" email address being populated from an XML list.
For example you have a list of offices and each office has a lead. I want to populate a List component with the office name, and when clicked I want it to open the email client and populate the To: and Subject line from the xml file.
What I have so far populates the Office name into the list and when clicked  the mail client will open but doesnt populate the To because I can't figure it out.
I believe I need to specify a var to pull the email address from the xml list, I just cant seem to get it right.
here is a snippet example of my xml code
<officeleads>
  <office>
   <officenm>PDX</officenm>
   <emllink>[email protected]</emllink>   <-------- I want this to populate the "To:" in an email
  </office>
</officeleads>
and here is my ActionScript
var leadloader:URLLoader = new URLLoader();
leadloader.addEventListener(Event.COMPLETE, onLoaded);
leadlist.addEventListener(Event.CHANGE, openMailClient);
function openMailClient(l:Event):void
var request:URLRequest = new URLRequest();
request.url="mailto:"                 <----------  this is where I know I need to somehow specify the emllink in the xml file to be filled into the "To:"
navigateToURL(request,"Self");
var xml:XML;
function onLoaded (l:Event):void
  xml = new XML(l.target.data);
  var offlst:XMLList = xml.office;
  for (var i:uint=0; i<offlst.length();i++)
   leadlist.addItem({data:offlst.officenm.text()[i],
       label:offlst.officenm.text()[i]});
leadloader.load(new URLRequest("officeleads.xml"));
Any help will be greatly appreciated.
Thanks

try:
import fl.events.ListEvent;
var leadloader:URLLoader = new URLLoader();
leadloader.addEventListener(Event.COMPLETE, onLoaded);
leadlist.addEventListener(ListEvent.ITEM_CLICK, openMailClient);
function openMailClient(e:ListEvent):void {
   var request:URLRequest=new URLRequest("mailto:"+leadlist.getItemAt(int(e.rowIndex)).data);
    navigateToURL(request,"_self");
var xml:XML;
function onLoaded(l:Event):void {
    xml = new XML(l.target.data);
    var offlst:XMLList = xml.office;
    for (var i:uint=0; i<offlst.length(); i++) {
       leadlist.addItem({data:offlst.emllink.text()[i],
               label:offlst.officenm.text()[i]});
leadloader.load(new URLRequest("officeleads.xml"));
