Datagrid help and RSS feed

Question

I am trying to get rss/xml into a datagrid. I am having trouble getting the feeds into the cells, the DataProvider is wrong?
function loaderCompleteHandler(event:Event):void {
    var rssXML:XML = new XML(loader.data);
    var pubCol:DataGridColumn = new DataGridColumn("puDate");
    pubCol.width = 150;
    var titleCol:DataGridColumn = new DataGridColumn("title");
    titleCol.width = 300;
    var myDP:DataProvider = new DataProvider(rssXML);
    aDg.columns = [pubCol, titleCol];
    aDg.width = 450;
          aDg.rowHeight = 40;
    aDg.dataProvider = myDP;
    aDg.rowCount = aDg.length;

Yes, but you should be still able to initialize it from an XML: http://help.adobe.com/en_US/ActionScript/3.0_UsingComponentsAS3/WS5b3ccc516d4fbf351e63e3d1 18a9c65b32-7fce.html
import fl.controls.DataGrid;
import fl.data.DataProvider;
var aDg:DataGrid = new DataGrid();
addChild(aDg);
var employeesXML:XML = 
    <employees>
        <employee Name="Edna" ID="22" />
        <employee Name="Stu" ID="23" />
    </employees>;
var myDP:DataProvider = new DataProvider(employeesXML);
aDg.columns = ["Name", "ID"];
aDg.dataProvider = myDP;
