Reading from external XML source

Question

Hi all,
I'm a noob at Flex but trying to learn.
I encountered a problem that i can't seem to fix.
I'm invoking an HTTPService like this:
Header 1
<mx:HTTPService id="searchName"url="
{compexUrl}"result="searchHandler(event)"
resultFormat = "
e4x">
 <mx:request xmlns="">
 <api_key>xxxxxxxx</api_key>
 </mx:request></mx:HTTPService>
Where compexUrl =
http://test/ + platform + "/" + searchTerms;
My searchHandler is like this:
[Bindable] 
public var item:XMLList = null; 
private function searchHandler(event:ResultEvent):void{item=
new XMLList(event.result);}
And the xml returned has the following aspect:
<?xml version="1.0" encoding="UTF-8" ?>
- <games xmlns="http://api.gamesradar.com">
- <game>
<id>20060418113640115000</id>
- <name>
- <![CDATA[ God Hand ]]>
</name>
</game>
- <game>
<id>2005120717012468975830</id>
- <name>
- <![CDATA[ God of War ]]>
</name>
</game>
- <game>
<id>20070510133243896018</id>
- <name>
- <![CDATA[ God of War Betrayal [mobile] ]]>
</name>
</game>
- <game>
<id>20060313151238825080</id>
- <name>
- <![CDATA[ God of War II ]]>
</name>
</game>
- <game>
<id>2005120717012341705322</id>
- <name>
- <![CDATA[ GoDai Elemental Force ]]>
</name>
</game>
- <game>
<id>2005120717012453155517</id>
- <name>
- <![CDATA[ Godzilla Save The Earth ]]>
</name>
</game>
- <game>
<id>20070918144248206042</id>
- <name>
- <![CDATA[ Godzilla: Unleashed ]]>
</name>
</game>
</games>
I want to populate my var item with all the values of the tag name but i can´t seem to figure out how?
Can you help me please?

Answer 1

Hi thanks for your reply but thats not the answer, i've tried that already....
My problem was that i had a namespace in my tags, aparently it changes the way we can access the attribute value
<games xmlns="http://api.gamesradar.com">
One way to deal with this namespace is to acces the variable like this:
var ns:Namespace = new Namespace("http://api.gamesradar.com");
item = XML(event.result).ns::game.*::name;
After i solved this issue i stumble upon another one, i wanted to put those results in a dataGrid like this:
 <mx:DataGrid x="10" y="101" width="786" id="searchInfo" dataProvider="{item}">
<mx:columns>
<mx:DataGridColumn headerText="Título" dataField="name"/>
<mx:DataGridColumn headerText="Identificador" dataField="id"/>
</mx:columns>
</mx:DataGrid>
Well Flex doesn't let me do that so i followed another route.....i simply removed the namespace from my xml with this function:
 public function result(response:Object):XML{
var xmlString:String;
var xmlnsPattern:RegExp;
var namespaceRemovedXML:String;
var responseXML:XML;
// get the XML payload
if(ResultEvent(response).result is XMLList){response = ResultEvent(response).result
as XMLList;}
else{response = ResultEvent(response).result
as XML;}
// convert it to a stringxmlString = response.toXMLString();
// define the regex pattern to remove the namespaces from the stringxmlnsPattern =
new RegExp("xmlns[^\"]*\"[^\"]*\"", "gi");// remove the namespaces from the string representation of the XMLnamespaceRemovedXML = xmlString.replace(xmlnsPattern,
// set the string rep. of the XML back to real XMLresponseXML =
new XML(namespaceRemovedXML);
return responseXML;}
Finally my handler was working and putting the values in my dataGrid by changing it to:
[Bindable]
public var item:XMLList = null;
private function searchHandler(event:ResultEvent):void{
item=result(event).game;
