I'm not convinced this is a complete solution: andru:~$ cat sub.pl #!/usr/bin/perl -p s{ <! # Comments start with <! ([^<>]|<[^<>]+>)* # Remove anything in between, including # the non-spec'ed included tags ... > # End of the comment. }{}gsx; # Replace with Nothing andru:~$ perl sub.pl <<!>!--#exec #cmd="/bin/echo foo"> <!--#exec #cmd="/bin/echo foo"> andru:~$ perhaps something like: while($value =~ /<!/) { ... } would be better... though I agree that the "correct" solution is to simply configure your server so that it doesn't parse the guestbook. andru
