newbie: How do I use Ruby on Rails to accept XML, parse it and store in a database?

[wchfilms]

I've gone through this excellent tutorial:
http://instantrails.rubyforge.org/tutorial/index.html
but I still can't quite wrap my brain around how to do what I want, and
being a newbie I'm finding it hard to know what to Google for.

Basically, I want to have a web service that accepts XML, parses it and
stores the data in a database. Seems simply enough conceptually. An
overview may be all I need, but I am having trouble finding it.

Any suggestions?
Thanks

And of course if Ruby on Rails makes no sense for this , let me know
that too
