If you are going to do this, make an ArrayCollection, you should build a class(value object, VO) with strongly typed public properties.
In the loop, "new" that class, then assign the xml node property values to the appropriate value object properties. Push that VO onto a temporary array. When the loop is done, wrap the array in an ArrayCollection.

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 --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Josh McDonald" <[EMAIL PROTECTED]> wrote: > > That's right, because when you trace the ArrayCollection it converts its > children to String, and your nodes have no inner text, so they toString() as > "". > > Instead of "addItem(item)", try "addItem([EMAIL PROTECTED])" > > -Josh > > On Fri, Jul 11, 2008 at 6:57 AM, sdl1326 <[EMAIL PROTECTED]> wrote: > > > Tracy, thanks for the very detailed reply.
