    ##
    # Return the text of the attribute. This is the default extractor used,
    # when no extractor is explicitly given.
    #
    # Imagine this HTML structure:
    #
    #     <p>Lorem <b>ipsum</b> dolor ...</p>
    #
    # YAML usage example:
    #
    #    selectors:
    #      description:
    #        selector: p
    #        extractor: text
    #
    # Would return:
    #    'Lorem ipsum dolor ...'
