New API for Custom Scrubbers

Instead of importing and requiring HtmlSanitizeEx.Scrubber.Meta, just use HtmlSanitizeEx:

defmodule MyScrubber do
  use HtmlSanitizeEx

  allow_tag_with_these_attributes("p", ["title"])
end

Using HtmlSanitizeEx also creates a sanitize/1 function in the module, so you can just call MyScrubber.sanitize(html).

allow_tag_with_these_attributes/3 is taking a do block, which allows specific handling of attribute/value pairs:

defmodule MyScrubber do
  use HtmlSanitizeEx

  allow_tag_with_these_attributes("p", ["title"]) do
    {"class", value} when value in ["red", "green", "blue"] ->
      {"class", value}
  end
end

The handler either returns a {attribute, value} pair or nil to scrub the value.

Extending existing Scrubbers

HtmlSanitizeEx can also be used for extending existing scrubbers:

defmodule MyScrubber do
  use HtmlSanitizeEx, extend: :basic_html

  allow_tag_with_these_attributes("p", ["title"])
end

You can extend :basic_html, :html5, :markdown_html and :strip_tags.

You can also extend any custom scrubber you created:

defmodule MyOtherScrubber do
  use HtmlSanitizeEx, extend: MyScrubber

  allow_tag_with_these_attributes("p", ["class"])
end

The result is a scrubber that works like the built-in BasicHTML scrubber, but also allows class and title attributes on <p> tags.
