Update actionscript

Any body out there help me update this actionscript so I can run it in flash player 7 and above please;
<code>
headlineXML = new XML();/*
headlineXML.onLoad = myLoad;
headlineXML.load(“headlines.xml”);

function myLoad(ok) {
if (ok == true) {
Publish(this.firstChild);
}
}
function Publish(HeadlineXMLNode) {
if (HeadlineXMLNode.nodeName.toUpperCase() == “BROADCAST”) {
content = “”;
story = HeadlineXMLNode.firstChild;
while (story != null) {
if (story.nodeName.toUpperCase() == “STORY”) {
lead = “”;
body = “”;
URL = “”;
element = story.firstChild;
while (element != null) {
if (element.nodeName.toUpperCase() == “LEAD”) {
lead = element.firstChild.nodeValue;
}
if (element.nodeName.toUpperCase() == “BODY”) {
body = element.firstChild.nodeValue;
}
if (element.nodeName.toUpperCase() == “URL”) {
URL = element.firstChild.nodeValue;
}
element = element.nextSibling;
}
content += “<font size=’+2’ color=’#3366cc’><a href=’”+URL+"’>"+lead+"</a></font><br>"+body+"<br><br>";
txt.htmltext = content;
}
story = story.nextSibling;
