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

The question is quite old, but you can call it in your test.rb like this:

ActionController::Base.helpers.strip_tags("<b>lol</b>") => "lol"

Answer 2

I believe this should be enough:

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

You can use Nokogiri as well:

require 'rubygems'
require 'nokogiri'
doc = Nokogiri::HTML("<b>lol</b>")
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("<b>lol</b>")
  end
end

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