XML repeat with same tags


I’m trying to create a simple news scroller. The scrollers is no problem, but I’m not good with XML. I am able to display a simple text in an .swf file with some AS code and an XML file. The problem is that I want to be able to display an number of sentences with the same tags. I want to have some AS code that checks if I have more of the same tags and then displays al of the scentences. I don’t want to use several dynamic textfields, I just want to use one, cause it’s easier and faster to edit the text.

This is the code I use in the .swf:

function  loadXMLTB(loaded)  {
    if (loaded) {
        _root.datum = this.firstChild.childNodes[0].childNodes[0].firstChild.nodeValue;
        _root.body = this.firstChild.childNodes[0].childNodes[1].firstChild.nodeValue;
        content_txt.htmlText += "<u>" + datum + "</u><br><br>"
        content_txt.htmlText += body +"<br><br>";
    } else {
          trace("file not loaded!");
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXMLTB;

and that’s the code I use in my XML file:

<?xml version="1.0"?>

    <datum>Datum: 29/03/2008</datum>

<datum>Datum: 29/03/2008</datum>
<body>bla blablablablabla


This is what I can display now in the .swf:

Datum: 29/03/2008

and this is what I want to be able to display:

Datum: 29/03/2008

bla blablablablabla

I hope you can understand what I want to do.
