Parsing feeds with Ruby and rFeedParser

[rFeedParser](http://github.com/jmhodges/rfeedparser/tree/master) is a Ruby version of the [feedparser Python library](http://feedparser.org), which is probably the best (not fastest) feed parser. To install it follow the instruction on the [project's GitHub page](http://github.com/jmhodges/rfeedparser/tree/master). ```ruby require 'rubygems' require 'rfeedparser' require 'benchmark' seconds = Benchmark.realtime do body = File.read('example-feed.xml') for num in (1..500) feed = FeedParser.parse(body) # Can be URL, string, data. end end puts "#{seconds.round} elapsed." ``` rFeedParser has one problem. In my simple test it was ~3-4 times slower than feed-normalizer and feedparser.org.
