I have some data like this: blah blah blah <iframe src="..." />

I can't seem to figure out how to strip the blah blah blah part. Is that possible?

You're probably thinking about it in the wrong way at least in SGML/XML/HTML5+ data outside of nodes are just plain text and you're not supposed to filter them out.

If you want to strip all plain text in tags, the following will work:

defmodule FastSanitize.Sanitizer.StripPlaintext do

  def scrub(x) when is_binary(x), do: nil

  def scrub(x), do: x
end

If you want to stip only plaintext at the root, that is not possible without modifying the code to provide parent tags for context to sanitizers
