Overview

This parser is a ::Nokogiri::HTML4::SAX style parser that reads its input as it deems necessary. The parser takes a ::Nokogiri::XML::SAX::Document, an optional encoding, then given an ::Nokogiri::HTML input, sends messages to the ::Nokogiri::XML::SAX::Document.

⚠ This is an ::Nokogiri::HTML4 parser and so may not support some ::Nokogiri::HTML5 features and behaviors.

Here is a basic usage example:

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

parser = Nokogiri::HTML4::SAX::Parser.new(MyHandler.new)

# Hand an IO object to the parser, which will read the HTML from the IO.
File.open(path_to_html) do |f|
  parser.parse(f)
end
