XML content used as a link to Open another window

Hi There. I am using the XML Flash tutorial found on this site:

<?xml version=“1.0” encoding=“utf-8” standalone=“yes”?>
<images>
<pic>
<image>http://www.kirupa.com/developer/mx2004/pg/kresge.jpg</image>
<caption>Kresge</caption>
</pic>

I am trying to make the image a link to open up another window…much larger,
How can I do this in XMl text file?

thx
