Link su titoli da xml

[Altamira]

ciao
ho questo codice che mi visualizza delle news, funziona benissimo,
ora però volevo fare in modo che di trasformare i titoli in link, e cliccandoli mi
visualizzasse il relativo testo del nodo desc in una textfield,
non saprei come modificarlo

var style_Data:TextFormat = new TextFormat();
style_Data.color = 0xFF0000;
style_Data.font = "mFont";


var style_Title:TextFormat = new TextFormat();
style_Title.color = 0xFFFFFF;
style_Title.font = "mFont";
style_Title.size = 10;

var style_Desc:TextFormat = new TextFormat();
style_Desc.color = 0xFFFFFF;
style_Desc.font = "mFont";
style_Desc.size = 10;


var xObj = 0;
var yObj = 0;
var widthObj = this._parent.mask._width;

function parseXML(xmlDoc)
{
    if (xmlDoc.loaded && xmlDoc.hasChildNodes)
    {
            var mytekst = xmlDoc.firstChild.childNodes;
            for (i = 0; i < mytekst.length; i++)
            {

                this.createTextField("Data"+i, this.getNextHighestDepth(), xObj, yObj, widthObj, 20);
                this["Data"+i].multiline = true;
                this["Data"+i].wordWrap = true;
                this["Data"+i].htmlText = mytekst[i].childNodes[1].firstChild.nodeValue;
                this["Data"+i].embedFonts = true;
                this["Data"+i].setTextFormat(style_Data); 
                this["Data"+i].autoSize = true;
                yObj += this["Data"+i]._height;

                this.createTextField("Title"+i, this.getNextHighestDepth(), xObj, yObj, widthObj, 20);
                this["Title"+i].multiline = true;
                this["Title"+i].wordWrap = true;
                this["Title"+i].htmlText = mytekst[i].childNodes[2].firstChild.nodeValue;
                this["Title"+i].embedFonts = true;
                this["Title"+i].setTextFormat(style_Title); 
                this["Title"+i].autoSize = true;
                yObj += this["Title"+i]._height;
                
                this.createTextField("Desc"+i, this.getNextHighestDepth(), xObj, yObj, widthObj, 20);
                this["Desc"+i].multiline = true;
                this["Desc"+i].wordWrap = true;
                this["Desc"+i].htmlText = mytekst[i].childNodes[3].firstChild.nodeValue;
                this["Desc"+i].embedFonts = true;
                this["Desc"+i].setTextFormat(style_Desc); 
                this["Desc"+i].autoSize = true;
                yObj += this["Desc"+i]._height;
            } // end of for
            if(this._parent.mask._height > this._parent.container._height){
                this._parent.arrowUp._visible = false;
                   this._parent.arrowDown._visible = false;
            }
        } // end if
        delete txtXML;
} // End of the function

stop();
var txtXML = new XML();
txtXML.ignoreWhite = true;
txtXML.onLoad = function (success)
{
    if (success)
    {
        parseXML(this);
        
    } // end if
};
_root.pagine.container.txtXML.load("crea_xml_db.asp?rnd=\"+random(99999);"); 

grazie
