Doing RSS, storing RSS

Does ruby on rails make it simple to grab a feed and then serialize it
into the database and the unserialize it from the database and allow
you to handle it as an object?

I know PHP can do this but can ruby do this? Do I need to make my own
RSS parser or does ruby have something?

Thank you for the reply, I actually had a discussion of the creator of
that prior to this post.

I resolved this issue by using a combination of a PHP script to do
this and to allow ruby to do the rest. This seems to be the most
efficient task.
