If a single quote exists, then will break out. eg: aabbcc - Should Match aa''bb''c''c - Should Match a''b - Should Match ab'' - Should Match aa'bbcc - Should not Match aa''bb'cc - Should not Match (since there is a single quote) 'aabcc - Should not MatchWhy use a regex? You can just test the evenness of the quotescount, see `perldoc -f tr`. A regex-way: m/\A(?:[^']*'[^']*')*[^']*\z/
The OP's examples fit this interpretation, but I assumed him to mean that "aa'bb'cc" would fail the match. We need to find out :) Rob -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
