Tracy, thanks for the very detailed reply. I changed the resultFormat=
'e4x'. So, I want to put the xml data into an arraycollection and am
trying the following code:
var xmlResult:XML = new XML(event.result);
xmlImages_ac = new ArrayCollection();
// push XML to ArrayCollection
for each(var item:XML in xmlResult.image){
xmlImages_ac.addItem(item);
}
trace('xmlImages_ac - ' + xmlImages_ac)
For whatever reason, I can not seem to get this to work as it simply
traces out:
xmlImages_ac - ,,,,
Can you point to where I am getting tripped up?
Thanks for the assistance.
