AS3 How to parse xml into an array

[Wisconsin]

I can load the xml, but I'm having trouble parsing it.

var myXML:XML;
var myLoader:URLLoader = new URLLoader();
myLoader.load(new URLRequest("fillinblank.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void {
myXML = new XML(e.target.data);
trace(myXML.QUESTION.INFINITIVE);
}

How do I turn this

<WORKSHEET>
    <QUESTION>
        <NUMBER>"1."</NUMBER>
        <BEGINNING>"Federico siempre"</BEGINNING>
        <MIDDLE>"llega"</MIDDLE>
        <END>"tarde."</END>
        <INFINITIVE>"llegar"</INFINITIVE>
        <ANSWER>"32894722213"</ANSWER>
    </QUESTION>
</WORKSHEET> 

into this?

var p1:Array=new Array("Federico siempre","llega","tarde.","llegar","32894722213");
