Populating ComboBox with XML data

Question

Hi there,
Probably the most basic question, but I'm having a hard time with this...
Trying to populate the ComboBox with XML data as a dataProvider.
Here is the code snippet:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                layout="vertical"
                creationComplete="baseDataRequest.send()">
    <mx:Script>
        <![CDATA[
            import mx.collections.XMLListCollection;
            import mx.rpc.events.ResultEvent;
            [Bindable]
            private var baseDataXML:XML;
            private function baseResultHandler(event:ResultEvent):void
                baseDataXML = event.result.node.child as XML;
        ]]>
    </mx:Script>
    <mx:HTTPService id="baseDataRequest"
                    useProxy="false"
                    resultFormat="e4x"
                    result="baseResultHandler(event)"
                    url="XML_URL"/>
    <mx:ComboBox id="comboDemo"
                 width="390"
                 dataProvider="{baseDataXML}"
                 labelField="NodeName"/>
</mx:Application>
And that returns nothing, basically. I know the XML is being pulled, because if I do this:
baseDataXML = event.result as XML;
then I just see a single item in my ComboBox, with full XML content.
How do I populate the ComboBox with XML contents?
XML example:
<root>
    <node>          <child>Child1</child>
          <child>Child2</child>
     </node>
</root>
Question: how do I populate the ComboBox with XML data nodes? I need <child> content to be the labelField of each combo box item...
Thanks!

     <mx:Script>
          <![CDATA[
               var baseDataXML:XML = <root><node><child>Child1</child><child>Child2</child></node></root>;
          ]]>
     </mx:Script>
     <mx:ComboBox id="comboDemo"
                 width="390"
                 dataProvider="{baseDataXML.node.child}"
                 labelField="NodeName"/>
Don't do:
baseDataXML = event.result.node.child as XML;
Instead just do:
baseDataXML = XML(event.result);
And in your combo:
dataProvider="{baseDataXML.node.child}"
