Using HTTPService to import data from a XML file

Question

Hello there!
I'm having some problem's with this import... If anyone can
help, I would appreciate it!
I'm using this type of information as data source:
public var dataCollection:ArrayCollection =
new ArrayCollection([
{ id: "P1", name: "Porto", type: "team", children: [
{ id: "R1", name: "Dr Silva", location: "Bloco 1", type:
"member" },
{ id: "R2", name: "Dra Neto", location: "Gabinete", type:
"member"
{ id: "P2", name: "Braga", type: "team", children: [
{ id: "R3", name: "Dr Santos", location: "Bloco 2", type:
"member" },
{ id: "R4", name: "Dra Sonia", location: "Piso 1", type:
"member"
But I want to import it from a XML file like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="P1" name="Porto" type="team">
<children id="R1" name="Dr Silva" location="Bloco 1"
type="member" />
<children id="R2" name="Dra Neto" location="Gabinete"
type="member" />
</item>
<item id="P2" name="Braga" type="team">
<children id="R3" name="Dr Santos" location="Bloco 2"
type="member" />
<children id="R4" name="Dra Sonia" location="Piso 1"
type="member" />
</item>
</items>
I already import the file, but can not translate the data
into a array collection.
private function initApp():void {
var httpService:HTTPService = new HTTPService();
httpService.url = "dataprovider.xml";
httpService.resultFormat = "e4x";
httpService.addEventListener(FaultEvent.FAULT,
onFaultHttpService);
httpService.addEventListener(ResultEvent.RESULT,
onResultHttpService);
httpService.send();
private function onFaultHttpService(e:FaultEvent):void
Alert.show("Error reading data file.");
private function onResultHttpService(e:ResultEvent):void
//Convert the xml data to a array collection
Thank you

Hello Peter, and thank you for your reply's.
My problem is that I'm receiving the data from the external
file and I don't know how to get the children in place... I mean, I
also have some data being received form a file that I can convert
into an array collection, but the thing is, that file doesn't have
children structure...
It's something like this:
<?xml version="1.0" encoding="utf-8"?>
<items>
<item id="T1" resourceId="R1" name="Cardiologia"
startTime="25-3-09 8:0:0" endTime="25-3-09 8:30:0" />
<item id="T2" resourceId="R2" name="Raio-X"
startTime="25-3-09 9:0:0" endTime="25-3-09 9:15:0" />
<item id="T3" resourceId="R3" name="Analises"
startTime="25-3-09 12:0:0" endTime="25-3-09 12:45:0" />
<item id="T4" resourceId="R4" name="Consulta"
startTime="26-3-09 8:0:0" endTime="26-3-09 9:0:0" />
</items>
And I solve it with this (don't know if is the best):
private function onResultHttpServiceTask(e:ResultEvent):void
var a:Array = xmlListToObjectArray(e.result.item);
tasks = new ArrayCollection(a);
protected function
xmlListToObjectArray(xmlList:XMLList):Array
var a:Array = new Array();
for each(var xml:XML in xmlList)
var attributes:XMLList = xml.attributes();
var o:Object = new Object();
for each (var attribute:XML in attributes)
var nodeName:String = attribute.name().toString();
var value:*;
value = attribute.toString();
o[nodeName] = value;
a.push(new ObjectProxy(o));
return a;
But when the children "enter in action" I don't know how to
bring them to the array...
This code you send it's preaty much the thing I need, but the
thing is that I don't know how to call the children with data as
e:ResultEvent...
If you can help a bit more, I would really appreciate...
Thank You
