XML newbie

I like trying out "cutting edge" stuff that I can't do at the day job on
my website. It's a truly never-ending project in which I'm always trying
to find better ways to do things.
 
At any rate, I think I have a good application for XML, but I can't seem
to bridge one gap in my understanding. I understand the wonderful things
I can do once I have my data in XML format, how I can format the page
for the web, for printing, for PDAs, and what-not. I recognize that all
my data that's now pretty well normalized lends itself to the
hierarchical format of XML. I suspect that if all my data were in XML, I
would only need to update that one XML document and the stylesheets
would take it from there. What I don't get is how I convert my existing
data in tables into XML efficiently and keep that XML document
up-to-date. Am I missing the point of XML? I feel like I'm going to end
up with two copies of my data. I also feel like I'm missing something
obvious. Any help or pointers are appreciated!
