I can't Hyperlink this XML


I’m starting with XML and Flash. I made a dynamic text field that reads my XML file but I need to hyperlink the description in the file and I can’t make it work. Here is the xml code I’m using:

<photo filename=“publicidade01.jpg” thumbnail=“publicidade01p.jpg” description=“abcdefgh 123” />

Can anyone help me make a hyperlink on the 123 part of the XML?
