XMLList to an array collection

[corbo950]

how do i convert XML or an XMLList to an arraycollection?

[lordofduct]

It kinda depends on your structure. And XML and XMLList are enumerable as well... so umm, could you expand on this a little bit?

I've the same problem...with a my custom Component

the code in my custom popUp that extends TitleWindows is:

<?xml version="1.0" encoding="utf-8"?>
<mx:TitleWindow xmlns:mx=" http://www.adobe.com/2006/mxml " layout="absolute" width="300" height="250" title="PopUp Info"
showCloseButton="true" close=" PopUpManager.removePopUp(this )" horizontalAlign="center" verticalAlign="middle" creationComplete=" unitRPC2.send( )">

<mx:Script>
<! CDATA[
import [mx.rpc.events.FaultEvent ;
import mx.managers.PopUpManager ;
import flash.events.MouseEvent ;
import mx.controls.* ;
import flash.net.FileReference ;
import mx.rpc.events.ResultEvent ;
import mx.collections.ArrayCollection ;

[Bindable]
public var idD:String;

[Bindable]
private var unitsDataGrid:ArrayCollection;

private function doLogin(e:MouseEvent):void {
PopUpManager.removePopUp(this );
trace( this.idD );
}



private function unitRPCResultXML(event:ResultEvent):void
{
unitsDataGrid = event.result.Items.Item.info ;
trace(unitsDataGrid);
}

private function faultHandler(event:FaultEvent):void{
var faultMessage:String = "Non posso connettermi al file XML";
Alert.show(faultMessage , "Errore nell'apertura del file");
}


]]>
</mx:Script>


<mx:HTTPService id="unitRPC2" url="assets/prova_popup_info.xml" result="unitRPCResultXML(event)" fault="faultHandler(event)" resultFormat="e4x"/>

<mx:Label id="labelUSER" text="{idD}" x="10" y="182" width="133"/>
<mx:DataGrid id="dataGrid" dataProvider="{unitsDataGrid}" x="10" y="10" width="260" height="164" />
</mx:TitleWindow>


the XML is very easy:
<?xml version="1.0" encoding="utf-8"?>
<ItemLookupResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://webservices.amazon.com/AWSECommerceService/2005-10-05">

But I can't understand how convert XMLList in ArrayCollection for my dataGrid...

You'll either need to use ADG / Tree, or write custom item renderers for your DG. DG is used to display flat data, i.e. only 1 nesting level, and your input has at least 3 levels.

See the example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
applicationComplete="applicationCompleteHandler()">

<mx:Script>
<![CDATA[
private function applicationCompleteHandler():void
{
var serviceNamespace:Namespace = xml0.namespace();
list0 = xml0..serviceNamespace::Item;
}
]]>
</mx:Script>

<mx:XML id="xml0">
<ItemLookupResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://webservices.amazon.com/AWSECommerceService/2005-10-05">
