Bold text, etc, from xml?

Using a photo slideshow from this site. Works great, thanx. The only problem I have is that I want to add text to describe the images. I want to be able to control linebrakes, boldness, linespacing etc. I also like to add some links within that text. Basically, I want this to work just like html text would…

The xml looks like this:

<?xml version=“1.0” encoding=“utf-8” standalone=“yes”?>
<title>Some text</title>
<text>More text</text>
