Load random image from XML file - actionscript-3

Question

I have almost non-existanl knowledge on AS3/Flash CS5.
I need to load a random image from an XML file with the list of urls.
Every time I load the movie, it should load a random image.
Any idea how to do this?

I'm assuming this is what your xml file looks like:
<images>
<image url="http://url_to_image/1.png" width="100" height="100" />
<image url="http://url_to_image/2.png" width="100" height="100" />
<image url="http://url_to_image/3.png" width="100" height="100" />
<image url="http://url_to_image/4.png" width="100" height="100" />
<image url="http://url_to_image/5.png" width="100" height="100" />
</images>
And here's what you'll do to get a random one from those:
private function randomImage(imagesXML:XML):Object {
var imageList:XMLList=imagesXML.image;
var imageCollection:XMLListCollection=new XMLListCollection(imageList);
var random:int=Math.floor(Math.random() * imageCollection.length);
var r:Object={};
r.url=xmlCollection[random].#url;
r.width=Number(xmlCollection[random].#width);
r.height=Number(xmlCollection[random].#height);
return r;
}
And here's how you would call it:
private var x:XML=<images>
<image url="http://url_to_image/1.png" width="100" height="100" />
<image url="http://url_to_image/2.png" width="100" height="100" />
<image url="http://url_to_image/3.png" width="100" height="100" />
<image url="http://url_to_image/4.png" width="100" height="100" />
<image url="http://url_to_image/5.png" width="100" height="100" />
</images>;
var img:Object=randomImage(x);
Now you have img.url, img.width, img.height
