Summary

Finds RSS and Atom feed urls in html like a hog finds truffles. Tasty, delicious feeds… er, truffles.

Description

This is a simple library. It doesn’t GET the html for you. It doesn’t use an HTML or XML parser. It just uses a little regex to find feed urls. If you want to GET the web pages, use Typhoeus. If you want to fetch and parse the feeds use Feedzirra.

Installation

  gem install truffle-hog --source http://gemcutter.org

Use

require 'rubygems'
require 'truffle-hog'

# get atom and rss
feed_urls = TruffleHog.parse_feed_urls(some_html)

# get atom if available, otherwise rss
feed_urls = TruffleHog.parse_feed_urls(some_html, :atom)

# get rss if available, otherwise atom
feed_urls = TruffleHog.parse_feed_urls(some_html, :rss)

Next

I may want to make a fun Nokogiri backed version and test speed and stuff. This thing hasn’t been benchmarked yet.
