Problem populating a button with XML

programming flash
1

Hey Everyone,
I am having a problem with populating a button with XML and having that xml say for the roll over effect. I got the XML to show up inside the _mc that I am using as a button.

Here is the code I am using to call the XML in:
//Load in XML
var data_xml:XML;
var xmlReq:URLRequest = new URLRequest(“xml/grassRoots.xml”);
var xmlLoader:URLLoader = new URLLoader();
XML.ignoreWhitespace = true;
//menu.homeBtn.home_txt.condenseWhite = true;

function xmlLoaded(event:Event):void
{
data_xml = new XML(xmlLoader.data);
menu.homeBtn.home_txt.htmlText = data_xml.menu.button1.title;
menu.homeBtn.homeBold_txt.htmlText = data_xml.menu.button1.title;
trace(data_xml);
}

xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
xmlLoader.load(xmlReq);

Here is my code for the roll over effect that I created a package for:
package
{
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
//import fl.controls.Button;

public class btnEffect extends MovieClip
{		
	public function btnEffect()
	{
		this.buttonMode = true;
		this.mouseChildren = false;
		this.addEventListener(MouseEvent.MOUSE_OVER, rollOn);
		this.addEventListener(MouseEvent.MOUSE_OUT, rollOff);
	}
	
	
	public function rollOn(event:MouseEvent):void
	{
		play();
	}
	
	public function rollOff(event:MouseEvent):void
    {
    	this.addEventListener(Event.ENTER_FRAME,revFrame);
    }
   
  	public function revFrame(event:Event):void
  	{
  		prevFrame();
		if(currentFrame == 1) 
		{
    		//trace("I'm done!!!");
			this.removeEventListener(Event.ENTER_FRAME, revFrame);
    	}
  	}
}

}

Everything works until I roll over the button, then once the playhead hits another keyframe for the text it goes blank. I just need it to populate the button at all times. Does this make sense as to what problem I am having?
I think it’s how I am calling in the xml, but I’m not all that experienced with as 3.
Thanks for your help in advance!!
