MyHTML

Build Status

Fast HTML5 Parser (Crystal binding for awesome lexborisov's myhtml and Modest). This shard used in production to parse millions of pages per day, very stable and fast.

Installation

Add this to your application's shard.yml:

dependencies:
  myhtml:
    github: kostya/myhtml

And run shards install

Usage example

require "myhtml"

html = <<-HTML
  <html>
    <body>
      <div id="t1" class="red">
        <a href="/#">O_o</a>
      </div>
      <div id="t2"></div>
    </body>
  </html>
HTML

myhtml = Myhtml::Parser.new(html)

myhtml.nodes(:div).each do |node|
  id = node.attribute_by("id")

  if first_link = node.scope.nodes(:a).first?
    href = first_link.attribute_by("href")
    link_text = first_link.inner_text

    puts "div with id #{id} have link [#{link_text}](#{href})"
  else
    puts "div with id #{id} have no links"
  end
end

# Output:
#   div with id t1 have link [O_o](/#)
#   div with id t2 have no links

Css selectors example

require "myhtml"

html = <<-HTML
  <html>
