I have a Synology NAS that is powered by linux at my house. I'm looking to set up a cron script to check a group of rss feeds and auto download new video podcasts to a shared folder. I can do most of the scripting, such as deleting files older than 3 weeks and the wget parts. But I'm not sure how to parse the rss feed and check dates to only grab the latest. I figured its best not to re-invent the wheel and surly someone out there has a command line rss downloader or some such script.
