I guess a very simple XML to AS3 question

My task is to show multiple items from the XML in a single textfield

My XML looks like this:

        <street>Singapore Street 55</street>
        <zip>SI-45678 Singapore</zip>
        <tel>Tel: +33 3333 3333</tel>
        <street>Yemen Street 33</street>
        <zip>YE-43434 Yemen</zip>
        <tel>Tel: +55 5555 5555</tel>

In my Flash AS3 file I have a dynamic textfield with the instance name: myTextblock

The code is the following:

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 itemlist:XMLList = xml.shop.shopname;
    myTextblock.text = itemlist[0]

loader.load(new URLRequest("./wheretobuy.xml"));

This displays the Shopname within the textfield. So far so good. Now I want not only the shopname, but also the city, the street and the telephone number to show up in my textfield and I have no idea how. Tried alot of stuff, but my AS3 knowledge lacks alot.

What to do? Thx ahead.
