How can I convert a simple XMLList to an Array of Strings without a loop?

How can I convert the following XMLList to an Array of Strings without using a loop?

<labels>
    <label>All</label>
    <label>your</label>
    <label>base</label>
    <label>are</label>
    <label>belong</label>
    <label>to</label>
    <label>us.</label>
</labels>

I want this result:

["All","your","base","are","belong","to","us."]

Right now, I am doing the following:

var labelsArray:Array /* of String */ = [];

for each (var labelText:String in labels.label)
{
    labelsArray.push(labelText);
}

I was wondering if there is a simpler way to do this in ActionScript 3.0

Your current implementation is more than sufficient. The only optimisation you could make (though I wouldn't bother unless you are using Vector.<>) is to pass in the initial capacity into the Array constructor:

var xmlLabels : XMLList = labels.label;
var labelsArray:Array /* of String */ = new Array(xmlLabels.length);

var index : int = 0;

for each (var labelText:String in xmlLabels)
{
    labelsArray[index++] = labelText;
}

for loops are extremely fast in AS. Why'd you need that? But you could give this a try:

private function toArray():void {
    var xml:XML = <labels>
               <label>all</label>
               <label>your</label>
              </labels>;

    var array:* = xml.label.text().toXMLString().split("\n") ;
    trace(array as Array);
}
