class Nokogiri::HTML4::SAX::Parser

Parent:: Nokogiri::XML::SAX::Parser

💡 This class is an alias for Nokogiri::HTML4::SAX::Parser as of v1.12.0.

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

Here is a basic usage example:

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

parser = Nokogiri::HTML4::SAX::Parser.new(MyDoc.new)
parser.parse(File.read(ARGV[0], mode: 'rb'))
