There is an issue with the approach suggested by Konstantin. It doesn't handle negative conditionals. See <a href="http://core.trac.wordpress.org/ticket/16118">http://core.trac.wordpress.org/ticket/16118</a>. If you need to support negative conditionals you will either require the patches in the Trac ticket or use the approach that I have suggested.<br>
