need a 's' modifier. from 'perldoc perlre': [Modifiers] s Treat string as single line. That is, change "." to match any character whatsoever, even a newline, which normally it would not match. Used together, as /ms, they let the "." match any character whatsoever, while still allowing "^" and "$" to match, respectively, just after and just before newlines within the string. Regards, Jeff.
