The second regex is a 'fix' regex which removes acronym tags from within other tags. That is: the initial regex is too agressive so I fix it by checking for acronyms inside angle brackets. Anyway, you could fix your situation in a similar way with a third line: <code>$text = preg_replace( "|<acronym[^>]*><acronym title="$description">$acronym</acronym></acronym>|imsU", "<acronym title="$description">$acronym</acronym>" , $text);</code> That should do it [:)] , but I haven't really tested it ...
