Showing RSS feed in Dynamic Text box (with hyperlink)

Question

Hi all -
I am currently trying to pull RSS data into a project for my first time and am trying to get 3 (potentially 4) boxes filled with rss data that will be updated. So far, I am going with Actionscript 3. So far I have the code below, but it puts data in a listbox. What is the easiest way to put the data in three dynamic text boxes inside a movie clip, so I have one for the title, one for description and one for link (shown as 'read more' text but a link using the url from the rss value)?
I am really banging my head against the wall on this one and want to get it sorted asap, so any help would be GREATLY appreciated! I have also attached an image to show what I am trying to do:
I also want to know if it's possible to show rss values only if they exist. For example, my xml feed currently only has 3 items that change, and i will be assigning these to boxes, but is it possible to display a fourth if it exists, and if it doesn't it just shows the first?
My code so far:
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoaded);
var xml:XML;
function onLoaded(e:Event):void
    xml = new XML(e.target.data);
    var il:XMLList = xml.channel.item.description};
    trace(il[1]);
         lb.addItem({data:il.description.text()
                            label:il.title.text()}):
loader.load(new URLRequest("http://www.rssfeedhere.xml"));

Answer 1

you would create a movieclip (exported for actionscript and class = rssItem) with 3 textfields and the display shown in your message and use something like:
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoaded);
var xml:XML;
function onLoaded(e:Event):void
    xml = new XML(e.target.data);
    var il:XMLList = xml.channel.item.description};
    for(var i:uint=0;i<il.length();i++){
        var mc:rssItem = new rssItem();
        addChild(mc);
        mc.x = 300*i%2;
        mc.y = 300*Math.floor(i/2);
        mc.titleTF.text = il[i].title.text();
        mc.descriptionTF.text = il[i].description.text();
        mc.readmoreTF.text = ?
loader.load(new URLRequest(http://www.rssfeedhere.xml));
