Ok, thanks.
So, looking at the original xml file ( below) if I want to add both
the name and url (data) to the array collection, is this the most
efficient way to accomplish this?
var xmlResult:XML = new XML(event.result);
xmlImages_ac = new ArrayCollection();
// push XML to ArrayCollection
for each(var item:XML in xmlResult.image){
var obj:Object = new Object()
obj.url = [EMAIL PROTECTED];
obj.name = [EMAIL PROTECTED];
xmlImages_ac.addItem(obj);
}
TIA
