How can I add rel="nofollow" attributes on RSS widgets?

Question

By default WordPress does not appear to have the option to add rel="nofollow" attributes on the RSS widgets.

<li>
    <a class="rsswidget" href="http://news.google.com/news/url...">
        The 60-Something Entrepreneur
    </a>
</li>

How can I make it so my RSS feed links have the rel="nofollow" attribute?

Answer 1

There seems to be no way to do that. You could filter 'clean_url' (like I did here), but I don't see a simple way to deactivate the filter when the RSS widget is rendered.

You could open a ticket on Trac and ask for a filter in wp_widget_rss_output() … from my experience wasted time, but there is no third option.
