To populate a tree with httpService

Question

Hi,
i don't arrive to populate my tree with an httpService.
Here is the code
<mx:Tree width="30%" height="100%" id="arboChambre"
labelField="@name"
dataProvider="{restree.lastResult.chambres.type}"
labelFunction="displayNodeName" />
and the script in <mx:Script>
private function displayNodeName( item:Object ) : String {
var node:XML = XML(item);
return node.@name;}
the xml returned by httpservice
<?xml version='1.0' encoding='utf-8' ?>
<chambres>
<type name="standart">
<chambre name="chambre1"/>
<chambre name="chambre2"/>
<chambre name="chambre3"/>
<chambre name="chambre4"/>
<chambre name="chambre5"/>
</type>
<type name="superieur junior">
<chambre name="chambre9"/>
<chambre name="chambre10"/>
</type>
</chambres>
And in my application i see only five icons files but not
directory and not name of the files (or directory ....)
Can you say me where is my mystake.

Thank for your answers and sorry for my english
here is my httpservice definition in my file.mxml
quote:
<mx:HTTPService id="restree" url="
http://lesite.com/index.php"
useProxy="false" method="POST" >
<mx:request xmlns="">
<action>
getTree
</action>
</mx:request>
</mx:HTTPService>
If i don't want to use lasResult , i think that i must call
the data in AS3 but it's difficult for me to understand the
documentation in english ;I tried to use URLLoader but when i
compile i have a lot of mistake.
is it the good way to use URLLoader in <mx:script>???
thank you
