Check if a URL is a valid Feed

Question

I'm using Argotic Syndication Framework for processing feeds.

But the problem is, if I pass a URL to Argotic, which is not a valid feed (for example, http://stackoverflow.com which is a html page, not feed), the program hangs (I mean, Argotic stays in an infinity loop)

So, How to check if a URL is pointing to a valid feed?

If you want to just have it transformed into valid RSS/ATOM, you can use http://feedcleaner.nick.pro/ to have it sanitized. Alternatively, you can fork the project.
