Get a href from xml file into a flash button - actionscript-3

Question

I have a flash file where I'm trying to change the value of the same button depending on the image that is clicked but I can't make it work with different values (I can only make it work with a static value).
AS:
var weblinkXML:XML = new XML();
weblinkXML.ignoreWhite = true;
weblinkXML.load("xml/main.xml");
weblinkXML.onLoad = function(success) {
trace("success = "+success);
for (var i:Number = 0; i< weblinkXML.childNodes.length; i++) {
PPTBUTTON.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage_1);
function fl_ClickToGoToWebPage_1(event:MouseEvent):void
{
navigateToURL(new URLRequest("test/test.html"), "_blank");
}
}
}
my XML:
<?xml version="1.0" encoding="iso-8859-1"?>
<content>
<!-- general vars -->
<settings>
<item name="copyright"><![CDATA[<font letterspacing="0.5">© 2012 | PRIVACY POLICY</font>]]></item>
<item name="companyName"><![CDATA[<font letterspacing="-2"><b>TANITA</b></font>]]></item>
<item name="companySlogan"><![CDATA[<font letterspacing="1">PHOTO PORTFOLIO</font>]]></item>
<!--mp3Url srcUrl="music.mp3"/-->
<imagesPage>
<image imageUrl="images/tfile_splash_pic_main.jpg" />
</imagesPage>
</settings>
<!-- menu -->
<menu>
<button><![CDATA[PORTFOLIO]]></button>
<button><![CDATA[ABOUT]]></button>
<button><![CDATA[NEWS]]></button>
<button><![CDATA[CONTACTS]]></button>
</menu>
<gallery gallName="Crystal Cabin Awards 2012">
<image imageUrl="gallery/tfile_gall_small_01.jpg" imagesBig="gallery/tfile_gall_big_01.jpg" buttonName="PPTBUTTON" targ="_self" href="http://www.google.com"/>
<image imageUrl="gallery/tfile_gall_small_02.jpg" imagesBig="gallery/tfile_gall_big_02.jpg" buttonName="PPTBUTTON" targ="_self" href="http://www.youtube.com"/>
<image imageUrl="gallery/tfile_gall_small_03.jpg" imagesBig="gallery/tfile_gall_big_03.jpg" buttonName="PPTBUTTON" targ="_self" href="http://www.yahoo.com"/>
<image imageUrl="gallery/tfile_gall_small_04.jpg" imagesBig="gallery/tfile_gall_big_04.jpg"/>
<image imageUrl="gallery/tfile_gall_small_05.jpg" imagesBig="gallery/tfile_gall_big_05.jpg"/>
<image imageUrl="gallery/tfile_gall_small_06.jpg" imagesBig="gallery/tfile_gall_big_06.jpg"/>
<image imageUrl="gallery/tfile_gall_small_07.jpg" imagesBig="gallery/tfile_gall_big_07.jpg"/>
<image imageUrl="gallery/tfile_gall_small_08.jpg" imagesBig="gallery/tfile_gall_big_08.jpg"/>
</gallery>
I realize my xml is complex but it's being used through the entire flash. Maybe I could reduce it to a stand alone xml just like:
<image imageUrl="gallery/tfile_gall_small_02.jpg" imagesBig="gallery/tfile_gall_big_02.jpg" buttonName="PPTBUTTON" targ="_self" href="http://www.youtube.com"/>
my issue is that I've tried to get the href into a variable and use it instead of "test/test.html" but it never works.
I also realize I have a method inside a for but at this point I've iterated so much over this code that I'm unsure how to proceed.

Here's how i would retrieve the list of href attributes:
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("xml/main.xml");
loader.addEventListener(IOErrorEvent.IO_ERROR, function errorHandler(event:IOErrorEvent):void {
trace("Error loading XML" + event.type);
});
loader.addEventListener(Event.COMPLETE, function(event:Event):void {
trace("success = " + event);
var xml:XML = new XML(loader.data);
var xmllist:XMLList = xml.gallery.children();
for (var i:Number = 0; i < xmllist.length(); i++) {
trace(XML(xmllist[i]).attribute("href"));
}
});
loader.load(request);
I had the following output:
success = [Event type="complete" bubbles=false cancelable=false eventPhase=2]

I hope that helps.
