Retrieving XML attribute value

Hi folks,
Realllly quick question. How do I go about retreiving the attribute value in the following XML script. In this case “atl” in the first child?

<?xml version="1.0" encoding="iso-8859-1"?>
<hotels>
	<prop id="atl">
		<name>Atlantic City</name>
		<lowest_rate>129</lowest_rate>
	</prop>
	<prop id="blv">
		<name>Georgetown</name>
		<lowest_rate>149</lowest_rate>
	</prop>
	<prop id="cac">
		<name>Miami</name>
		<lowest_rate>169</lowest_rate>
	</prop>
	<prop id="las">
		<name>Las Vegas</name>
		<lowest_rate>169</lowest_rate>
	</prop>
</hotels>

And here’s my AS:

var xmlMe:XML = new XML();
xmlMe.ignoreWhite = true;
xmlMe.load("lowest_rate.xml");

xmlMe.onLoad = function(p_success:Boolean){
trace("::CODE IS SUCCESSFUL::");
//Below is a sample XML path, you will need to confirm
//the correct path for your needs.
trace(this.firstChild.attributes.path);
};

Obviously, my trace isn’t bringing up the right value…
Any help would be greatly appreciated!
