That is not as bad as I thought it might be(I was expecting to see the default resultFormat. E4x is good!), but it is a bit odd. You are manually building an ArrayCollection of XML nodes.
I don't see any reason to do that. Just use XMLListCollection, and avoid the loop. Now, "best practice", or at least this list's apparent consensus of best practice, is to do what you are doing, but instead of adding xml nodes, you populate a strongly data typed "Value Object" and add tht to the ArrayCollection. This is probably the most efficient and performant approach. But I mostly use XML and XMLListCollection.

Hi Tracy, this is how I get the XML info into an ArrayCollection: <mx:HTTPService url="days.php" useProxy="false" method="POST" id="Days" resultFormat="e4x" result="get_days(event)"> private function get_days(event:ResultEvent):void { Arraydays.removeAll(); XMLdays = event.result as XML; for each(var ourxml:XML in XMLdays.elements()) Arraydays.addItem(ourxml); } Is this ok?

I suggest using e4x expressions against the XML, and then putting the result in an XMLListCollection. var xlResults:XMLList = xmlData.result. (attribute("id") == "1"); trace(xlResults. toXMLString( )); //to verify your data xlcResults = new XMLListCollection( xlResults) ; You did not say how you got your XML into an ArrayCollection, but I suspect it is not the good way.
