xml is just used to organize information; it does not in an of itself, actually
do anything.
It's more or less akin to comma or tab delimited text.
Here's a basic example:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<SLIDESHOW>
<IMAGE PATH="images/img0.jpg" CAPTION="description of image"/>
<IMAGE PATH="images/img1.jpg" CAPTION="description of image"/>
<IMAGE PATH="images/img2.jpg" CAPTION="description of image"/>
<IMAGE PATH="images/img3.jpg" CAPTION="description of image"/>
<IMAGE PATH="images/img4.jpg" CAPTION="description of image"/>
</SLIDESHOW>
