Module Loofah::ScrubBehavior
In: lib/loofah/instance_methods.rb

Mixes +scrub!+ into Document, DocumentFragment, Node and NodeSet.

Traverse the document or fragment, invoking the scrubber on each node.

scrubber must either be one of the symbols representing the built-in scrubbers (see Scrubbers), or a Scrubber instance.

  span2div = Loofah::Scrubber.new do |node|
    node.name = "div" if node.name == "span"
  end
  Loofah.fragment("<span>foo</span><p>bar</p>").scrub!(span2div).to_s
  # => "<div>foo</div><p>bar</p>"

or

  unsafe_html = "ohai! <div>div is safe</div> <script>but script is not</script>"
  Loofah.fragment(unsafe_html).scrub!(:strip).to_s
  # => "ohai! <div>div is safe</div> "

Note that this method is called implicitly from Loofah.scrub_fragment and Loofah.scrub_document.

Please see Scrubber for more information on implementation and traversal, and README.rdoc for more example usage.
