  ##
  # === HtmlKit::Document
  #
  # Used for parsing urls which are `http` or `https`
  # You can use this to validate a html document. This uses nokogiri internally.
  # Warning: Currently doesn't support HTML5 tags
  #
  # For example (from irb):
  #
  #  irb(main):001:0> require 'html_kit'
  #  => true
  #  irb(main):002:0> doc = HtmlKit::Document.new('http://www.nokogiri.org/index.html')
  #  => #<HtmlKit::Document:0x007fbb5408cfe8 @url="http://www.nokogiri.org/index.html">
  #  irb(main):003:0> doc.valid?
  #  => false
