I think she wants to know how to, erm, "write" Podium settings files. My advice: no need for that. There's a couple of really nice ones over at the Podium forum. Look for Zirak's and Biebel's settings files.
Also, as far as I know, xml file editing will be a thing of the past when Podium 2.0 is released. Which, obviously, is groovy. š
