xml to text field via array.

I am loading my xml document into a text field, via an array. I am
wondering, how I can do this and then take out the commas that the array
is adding?

I am bringing my content in like this:

var aInfoText:Array = new Array;
this.scroller_all.scroller_slider.infoScroll.textbox.autoSize = true;

var xmlContent:XML = new XML();
xmlContent.ignoreWhite = true;
xmlContent.onLoad = function(bSuccess:Boolean):Void {
if(bSuccess){
trace("Loaded the xml successfully");

var xnRoot = this.firstChild;
var xnInfo = xnRoot.childNodes[0];

for(var i:Number = 0; i < xnInfo.childNodes.length; i++){
aInfoText.push(xnInfo.childNodes .firstChild.nodeValue);

if(i == xnInfo.childNodes.length - 1){

scroller_all.scroller_slider.infoScroll.textbox.htmlText = aInfoText;
}
}
}
};
xmlContent.load("about.xml");


The content in the XML document looks like this:

<the_content>
<info_text>
<section_header>INFO</section_header>

<headline>Some headline</headline>
<bodycopy>Some content</bodycopy>

<headline>Some headline</headline>
<bodycopy>Some content</bodycopy>
</info_text>
</the_content>



The commas show between the childNodes, but I don't want them there at
all. How would I do that?

Thanks a lot!
