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.
#!/usr/bin/env ruby
require 'rubygems'
require 'open-uri'
require 'nokogiri'
doc = Nokogiri::HTML(open(''))
img_src = doc.css('img.closures').first['src']
if img_src.match /West/
puts 'Westbound'
elsif img_src.match /East/
puts 'Eastbound'
puts 'Closed'
