Load external XML into DataGrid with AS3

Question

I've really looked hard to find an example/tutorial for
loading external XML data into a DataGrid component using AS3. The
code I'm using at the moment has the XML data in the AS code. If
anyone can point me to a good resource(s) for code or a tutorial
I'd be very appreciative. It needs to be AS3. ~steve
Here is the code that is working for internal XML data:
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;
stop();
var emailXML:XML = <emails>
<email date="06-04-07" code="EMRPAAV" campaign="This is
the campaign details."/>
<email date="06-11-07" code="EMRPAAW" campaign="This is
the campaign details."/>
<email date="06-18-07" code="EMRPAAX" campaign="This is
the campaign details."/>
<email date="06-25-07" code="EMRPAAY" campaign="This is
the campaign details."/>
<email date="07-02-07" code="EMRPAAZ" campaign="This is
the campaign details."/>
<email date="07-09-07" code="EMRPABA" campaign="This is
the campaign details."/>
</emails>;
var dateCol:DataGridColumn = new DataGridColumn("date");
dateCol.headerText = "Date";
dateCol.width = 60;
var codeCol:DataGridColumn = new DataGridColumn("code");
codeCol.headerText = "Source Code";
codeCol.width = 70;
var campaignCol:DataGridColumn = new
DataGridColumn("campaign");
campaignCol.headerText = "Campaign";
campaignCol.width = 300;
var myDP:DataProvider = new DataProvider(emailXML);
emailData.columns = [dateCol, codeCol, campaignCol];
emailData.width = 440;
emailData.dataProvider = myDP;
emailData.rowCount = emailData.length;
// end code

Here is how you build it for external XML. in my example am
using the same xml format that you are using . The xml file called
"dataGrid.xml"
import fl.controls.dataGridClasses.DataGridColumn;
import fl.data.DataProvider;
import fl.containers.UILoader;
import fl.data.DataProvider;
import fl.events.*;
import flash.xml.*;
var emailXML:XML;
var myList:XMLList;
function parseXML():void
var url:String = "dataGrid.xml";
var urlRequest:URLRequest = new URLRequest(url);
var loader:URLLoader = new URLLoader();
loader.addEventListener("complete" , loadXML);
loader.load(urlRequest);
/*var emailXML:XML = <emails>
<email date="06-04-07" code="EMRPAAV" campaign="This is
the campaign details."/>
<email date="06-11-07" code="EMRPAAW" campaign="This is
the campaign details."/>
<email date="06-18-07" code="EMRPAAX" campaign="This is
the campaign details."/>
<email date="06-25-07" code="EMRPAAY" campaign="This is
the campaign details."/>
<email date="07-02-07" code="EMRPAAZ" campaign="This is
the campaign details."/>
<email date="07-09-07" code="EMRPABA" campaign="This is
the campaign details."/>
</emails>
parseXML();
function loadXML(evt:Event):void
emailXML = new XML(evt.target.data);
myDP = new DataProvider(emailXML);
emailData.dataProvider = myDP;
var dateCol:DataGridColumn = new DataGridColumn("date");
dateCol.headerText = "Date";
dateCol.width = 60;
var codeCol:DataGridColumn = new DataGridColumn("code");
codeCol.headerText = "Source Code";
codeCol.width = 70;
var campaignCol:DataGridColumn = new
DataGridColumn("campaign");
campaignCol.headerText = "Campaign";
campaignCol.width = 300;
var myDP:DataProvider;
emailData.columns = [dateCol, codeCol, campaignCol];
emailData.width = 440;
emailData.dataProvider = myDP;
emailData.rowCount = emailData.length;
