XML and Flash - Yikes!

Question

HELP!
I think I might be in trouble unless someone brilliant can help.
I'm working with a flash template that loads external images and text using an xml file.
Everything works well the only problem is I've promised a client that as well as a "title" and "description" I will also include a clickable URL link. I can edit the flash to a certain extent but I am having a nightmare of a time including a clickable url. Is there anyone out there who can help?
"photo_description", "photo_title" and "photo_url" are the names of the dynamic text fields.
XML snippet looks a little like this...
<title>Title</title>
<description>Description</description>
<url>http://</url>     <---- This is the part I'd like to include
Here is the AS...

Thank you! Thank you! Thankyou!

I´m not quite understanding what you are trying to do here, but in my opinion it would be cleverer to let Flash handle the Link and not the XML.
Look into the navigateToURL function, formerly (AS2) known as getURL.
Include your server path as a variable like:
var baseurl = 'http://www.mypictures.com/descriptions/';
and in your MouseEventListeners build the path dynamically:
var descriptionURL:String = aHref();//write a function to get the right Link here;
var request:URLRequest = new URLRequest(baseurl + descriptionURL);
    try{
        navigateToURL(request,"_blank");
    catch(e:Error){
        trace("An error occurred");
in your XML you will now only need sth. like  <description>description.txt</description>
