How can I use strip_tags in regular Ruby code (non-rails)?

Question

I need to turn HTML into plain text. There\'s a nice function that does that in ActionView\'s SanitizeHelper, but I have trouble understanding how I can reference it and use

Answer 1

I believe this should be enough:

"lol".gsub(/<[^>]*>/ui,'') #=> lol

You can use Nokogiri as well:

require 'rubygems'
require 'nokogiri'
doc = Nokogiri::HTML("lol")
doc.text #=> "lol"

You still can go with the Rails one by doing something like:

require 'rubygems'
require 'action_view'

class Foo
  include ActionView::Helpers::SanitizeHelper

  def test
    strip_tags("lol")
  end
end

f = Foo.new
puts f.test #=> lol
