What is the preferred method to remove an empty tag from the content of a rich text element?
<p> Lorem<a href="…"></a> ipsum </p>
When editing text in the WYSIWYG editor (Redactor) the result can contain empty anchor tags. This is a problem when navigating the page with the tab key, for instance, because the user can not see the focus anymore.
How can I automatically remove those artefacts?
