Parse Clickbank Marketplace

I would like an application written that will go and download the latest clickbank xml file (found at [[login to view URL]][1]), parse it and save to to a database. I would like to be able to tell the program when to run (ie daily or weekly) and what time of day to fetch the file and perform the update. Please indicate what programming language you will use and what database you will use. At a later time I would like to add a web front end to this in order to query the data.
