Idea: perhaps we can use a stream HTML parser, avoiding the linkification when
we are inside an inappropriate element. Something like this:
```
UNLINKABLE_ELEMENTS = ["pre", "code", "a"]
unlinkable_elements_stack = []
parser = StreamingParser.new(html) do |events|
events.on_opening_element do |element|
unlinkable_elements_stag.push(element.tag_name) if
UNLINKABLE_ELEMENTS.include?(element.tag_name)
end
events.on_closing_element do |element|
element.text = linkify(text) if inappropriate_elements_stack.empty?
unlinkable_elements_stag.pop if
UNLINKABLE_ELEMENTS.include?(element.tag_name)
end
end
parser.run
```
I'm totally making up the API above. Nokogiri has something like it, but I
don't remember the detail now. LibXML probably has it too.
