# A solution to: http://sites.google.com/site/tddproblems/all-problems-1/URL-splitting

class UrlSplitter
  def self.split(url)    
    match = url.match /(\w+):\/\/([^\/]+)(\/|$)(.*)?/
    results = {:protocol => match[1], :domain => match[2]}
    
    if match[4] == ""
      results[:path] = nil
    else
      results[:path] = match[4]
    end
    results
  end
end

Well done! As a possible improvement, when you don't assign a value to a hash key, trying to access it evaluates to nil if you don't fill it with a value, so you could skip part of the if/else sentence:

results[:path] = match[4] unless match[4] == ""

Thanks for sharing your solution! :)

That's much more elegant - thanks!

Alberto got the working regex, so he deserves the credit on this one :)
