Help with coding an action

Ok I’m not so good at coding so any help is greatly appreciated. I have an RSS feed thing made in flash. It works great except every the page is reloaded you have to click a button to get the feed to show up. Can somebody help me alter the code so that it loads by itself rather then by clicking the button? Thanks!

Here is the code:
// ************************************************
// Load XML data
// ************************************************
btnLoad.onRelease=function(){
loadDATA();
}

function loadDATA(){
var rss_xml:XML = new XML();
rss_xml.ignoreWhite = true;
rss_xml.onLoad = function(success:Boolean) {
if (success) {
processData(rss_xml);
} else {
trace(“unable to load/parse cnet.xml”);
}
};
rss_xml.load(txtURL.text);
}
