Method to parse HTML document in Ruby?

Question

like DOMDocument class in PHP, is there any class in RUBY (i.e the core RUBY), to parse and get node elements value from a HTML Document.

Answer 1

Ruby Cheerio - A jQuery style HTML parser in ruby. A most simplified version of Nokogiri for crawlers. This is the ruby version of most popular NodeJS package cheerio.

Follow the link for a simple crawler example.

gem install ruby-cheerio

require 'ruby-cheerio'

jQuery = RubyCheerio.new("
h1_1
h1_2
")

jQuery.find('h1').each do |head_one|
    p head_one.text
end

# getting attribute values like jQuery.
p jQuery.find('h1.one')[0].prop('h1','class')

# function chaining similar to jQuery.
p jQuery.find('body').find('h1').first.text
