A simple script for extracting the unicodes and the icon names from the Font Awesome cheat-sheet page.

Ruby_WebScrapping_FontAwesomeCheatSheet.rb

require 'net/http'

#Reads the HTML page
fontAwesomeUri = URI('http://fortawesome.github.io/Font-Awesome/cheatsheet/')
htmlSourceArray = Net::HTTP.get(fontAwesomeUri).split(/\r?\n/)
outputArray = Array.new()
tempString = String.new()
#Extracts the lines containing the unicodes and the icon names
htmlSourceArray.each_with_index do |line,index|
  line = line.strip
  if(line =~ /<i class="icon-fixed-width">&#x(....)<\/i>/ )    
   tempString = "0x"+ $1 + " , " + htmlSourceArray[index+1].strip + "\n"
   outputArray.push(tempString)
  end
end
#Prints to output.txt the results
outputFile = File.open("output.txt","w")
outputArray.each do |line|
  outputFile.write(line)
end

puts("Extracted " + outputArray.size().to_s() +
     " items from the Font-Awesome cheatsheet. Hurray!")
