Check status of the Tampa Crosstown Expressway’s reversible express lanes in Ruby. Tampa–Hillsborough Expressway Authority doesn’t offer an API, so it uses Nokogiri to scrap the official website’s status display.

selmon.rb

#!/usr/bin/env ruby
require 'rubygems'
require 'open-uri'
require 'nokogiri'

doc = Nokogiri::HTML(open('http://www.tampa-xway.com/'))
img_src = doc.css('img.closures').first['src']

if img_src.match /West/
  puts 'Westbound'
elsif img_src.match /East/
  puts 'Eastbound'
else
  puts 'Closed'
end
