XML Feeds

Hello people,

I am having some problems gaining a response from this and am wondering what I am doing wrong.

The information can be found here, http://www.foundation-flash.com/tutorials/xml/ , however for those of you too lazy to click the link, here it is.

My Flash action script is as follows

var cats_xml = new XML();
cats_xml.onLoad = function(loaded){
if (loaded){
trace(cats_xml.firstChild.firstChild.nodeValue);
trace(cats_xml.firstChild.firstChild.nextSibling.nodeValue);
}
}
cats_xml.load(“cats.xml”);

and my XML is as follows

<cats>
<title>
CATS!
</title>
<cat>
Meow!
</cat>
<cat>
Meow!
</cat>
<cat>
Meow!
</cat>
<cat>
Meow!
</cat>
<cat>
Meow!
</cat>
</cats>

to the best of my knowledge this should produce an output ie trace of

CATS!
Meow!

however when I try and publish my movie i get an output of “null”

can any one explain to me why I am not getting the desired output.
please help as I have been trying to sort this for a couple of days now and it doing my head in.

Any help would be very much appreciated

Cameron

P.S. Please bear in mind I am fairly new to actionscript and xml so please treat me like an idiot.
