Need a feed aggregator

Idea behind this site is to aggregate interesting blogs / discussions
related to software testing field and keep it at one place. Have a
look at the http://www.testingreflections.com/ , this site pretty
much provides the similar functionality. The way it would work is -

  1. In the admin system I’ll provide some information about the feed
    this i will do

    • Name for the feed
    • Address of the fee (XML file address on the internet)
  2. Based on this information - there should be some periodic job which
    will run at a specific time, fetch latest article etc from their feed
    and populate in our DB (give idea about this )

  3. Look at couple of feeds - they should all have similar fields and
    we need to extract all the relevant data from them.

  4. This aggregator should support all the popular feed format like -
    RSS / ATOM etc
