    # Imagine this HTML:
    #    <h1>Foo bar and boo<h1>
    #
    # YAML usage example:
    #    selectors:
    #      title:
    #        selector: h1
    #        post_process:
    #         name: gsub
    #         pattern: boo
    #         replacement: baz
    #
    # Would return:
    #    'Foo bar and baz'
    #
    # `pattern` can be a Regexp or a String.
    # `replacement` can be a String or a Hash.
    # See the doc on [String#gsub](https://ruby-doc.org/core/String.html#method-i-gsub) for more info.
