Dvd catalogue ( simple)

I would like to create a simple dvd catalogue. I dont want to utilize a database, but either an editable txt file or xml. Can someone help me out with this? I need to be able to catalogue how many dvds I have, the titles, who has them at the moment, etc.

I would love to be able to call up the txt file and edit it. I know it would be easier to use a server side code, but I would prefer not to.

thanks in advance.
