xml handling class

hi

i am writing a class to handle import rss feeds, but can't seem to progress from loading the xml. on creating the Rss_Test object, it outputs "rss loaded" but nothing else - i am guessing it is a scope thing. any ideas?

Code:

---

class Rss_Test {
        var rss_items:Array;
        var rss_item:Array = new Array();
        var rss_xml:XML;
       
        public function Rss_Test(xml_feel_url) {       
                rss_xml = new XML();
                rss_xml.ignoreWhite = true;
                rss_xml.onLoad = function(loaded:Boolean) {
                        if(loaded) {
                                trace("rss loaded");
                                parse_rss_xml();
                        }else {
                                trace("booch");
                        }
                }
                rss_xml.load(xml_feel_url);
        }
       
        private function parse_rss_xml() {
                // this never gets executed
                trace("executing: parse_rss_xml()");
                // blah blah blah
        }
}
