How to programmatically determine whether an RSS feed is a full feed or a partial feed

Question

I would need to programmatically determine whether an RSS feed exposes the full content of its articles or just extracts of them. How would you do it?

Answer 1

Why not follow the url from the rss-feed and check whether there is more text on this page than in the rss-feed? You would need take a html-parser and put in some general rules.
