Creating an ActionScript 3 RSS looping feed - actionscript-3

Question

I have the following AS3 code so far. What I need to do is have this code continually loop the feed it is consuming. Any solutions?
import flash.text.TextField;
import flash.text.TextFormat;
import flash.net.URLLoader;
import flash.events.IOErrorEvent;
//Read RSS feeds
var RSS_xmlData: XML = new XML();
var xmlLoader: URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
xmlLoader.load(new URLRequest("http://www.oshawa.ca/news_rss.asp"));
function LoadXML(e:Event):void {
dtext.text="Loading...";
RSS_xmlData = new XML(e.target.data);
}
function pullFeed(rss: XML):void {
var str: String="";
str = rss.channel.item.title;
str = str.replace(/\s*\n/g," | ");
str = str.replace(/'/g,"\"");
//// shows specific entry
var items: Array = new Array();
items = str.split("|");
var tf: TextField = dtext;
var i:Number=0;
var myTimer:Timer = new Timer(4000,items.length);
myTimer.addEventListener(TimerEvent.TIMER, timerListener);
function timerListener (e:TimerEvent):void{
tf.text = items[i].toString();
scaleTextToFitInTextField(tf);
i++;
}
myTimer.start();
}
function scaleTextToFitInTextField(txt: TextField):void {
var f: TextFormat = txt.getTextFormat();
f.size = (txt.width > txt.height) ? txt.width : txt.height;
txt.setTextFormat(f);
while (txt.textWidth > txt.width - 4 || txt.textHeight > txt.height - 6) {
f.size = int(f.size) - 1;
txt.setTextFormat(f);
}
}
function onIOError(e:IOErrorEvent):void
{
trace(e.toString());
dtext.text="Finding Feed...";
}
I have tried a while loop, a for loop and a timer reset and restart but none appear to enable me to continually loop the feed.
Thanks

Reset your counter when you've finished iterating over your array:
function timerListener (e:TimerEvent):void{
tf.text = items[i].toString();
scaleTextToFitInTextField(tf);
// Reset counter to 0 when we've been all the way through the array
i = i < items.length - 1 ? i + 1 : 0;
}
