Display news from wordpress blog within app

I’ve got a wordpress blog in a totally different database. I’d like to
take the five most recent articles and display them within my app, as
well as possibly display associated comments and such. This seems to be
a better idea than adding in such functionality to my app. I’m thinking
that what I’m trying to do is possible by perhaps using the blog’s RSS
feeds, but I don’t know how to go about reading and displaying them.
Ideally I could capture each entry into something like an object with
things like the date, author, etc becoming attributes. How should I go
about this? If I do this, is it possible to also cache the results?
Thanks in advance.

Gonna try to bump this before it fades into oblivion.
