Stupid new (to PCRE) question

Am I the only one that can't make this work? <? $s = "foo <A> <a> <BAa>"; preg_replace("/(<\/?)(\w+)([^>]*>)/e", "'\\1'.strtoupper('\\2').'\\3'", $s); print "\n\$s => $s.\n"; ?> X-Powered-By: PHP/4.0RC2-dev Content-type: text/html $s => foo <A> <a> <BAa>. ^^^^^^^^^^^^^^^^^^^^^^^^ Shouldn't this be: $s => foo <A> <A> <BAA>. ? --Joey Smith Please forgive the long sig: *** Notice To Bulk Emailers: Attention!
