Overview

This class lets you perform SAX style parsing on HTML with HTML error correction.

class MyDoc < Nokogiri::XML::SAX::Document
  def start_element name, attributes = []
    puts "found a #{name}"
  end
end

parser = Nokogiri::HTML::SAX::Parser.new(MyDoc.new)
parser.parse(File.read(ARGV[0], 'rb'))
