quick Nokogiri script to pull headlines out of news articles

headlines.rb

require 'rubygems'
require 'nokogiri'
require 'open-uri'

# Takes a URL for a news site (like Huffpo or Yahoo) as input and outputs the Headline

url = ARGV[0]

resource = NokoGiri::XML(open(url))

# any news site should have only one h1 and the h1 should be their headline,
# but who knows?
resource.search("h1").each do |h1|
  puts h1.text # will discard all elements that may be in an H1 and only output text
end

# NOTE: This is completely from memory and untested, there may be bugs
