Simple RSS Feed scraper

I am looking for a PHP script that will take an existing chosen RSS feed go to the URL and scrape the WHOLE article and store that article in database. I will need to be able to enter multiple RSS and choose article program will scrape. Because I will be using RSS 0.9, 1.0 and 2.0 it might be a good idea to build around lastRSS or some other already developed RSS scripts but this is not necessary. Please see attached specification for detailed information. This will be used in my Hoodia site under ([login to view URL]). Link and credit to source website will be given on all articles. Don't bid if you don't have positive feedbacks.
