I had a similar situation with ArrayCollection. what I do it iterate
through the collection and return the item if I find one that matches.
I created an ArrayCollectionIterator Class that helps with this.
public class ArrayCollectionIterator implements IIterator {
private var collection:ArrayCollection;
private var nextIndex:Number = 0;
public function
ArrayCollectionIterator(collection:ArrayCollection) {
this.collection = collection;
}
public function hasNext():Boolean {
return (this.nextIndex<this.collection.length);
}
public function next():Object {
if(!this.hasNext()) {
throw new Error("No more elements
available");
}
var obj:Object = this.collection[this.nextIndex];
nextIndex++;
return obj;
}
public function reset():void {
nextIndex = 0;
}
}
So the idea is I have a function that querys the list and returns the
item if found and null if not. Then with the calling function I
either add or update based on the response. Let me know if you need
more specific eexamples. You should be able to adapt the above Class
to use the XMLListCollection.
