Re: RegEx question

If you mean "something that isn't bank" (as you said),

/
   ^
   (?: .{0,3} | (?!bank}.{4} | .{5,} )
   nova [ ] scotia
   (?: .{0,3} | (?!bank}.{4} | .{5,} )
   $
/sx
[download]

Alternative:

/
   ^
   (?: | [^b].* | b[^a].* | ba[^n].* | ban[^k].* | bank.+ )
   nova [ ] scotia
   (?: | [^b].* | b[^a].* | ba[^n].* | ban[^k].* | bank.+ )
   $
/sx
[download]

If you mean "something that doesn't contain bank",

/
   ^
   (?: (?!bank). )*
   nova [ ] scotia
   (?: (?!bank). )*
   $
/sx

Sure, just squish it all together (untested) `/^(?:(?!bank).)nova[ ]scotia(?:(?!bank).)$/` and remember that `.` (dot) no longer "matches all." But why would you want to? Update: Actually, you no longer need the character class (update: because without `/x` a space is a literal space): `/^(?:(?!bank).)nova scotia(?:(?!bank).)$/` and if you just gotta get rid of that last space: `/^(?:(?!bank).)nova\x20scotia(?:(?!bank).)$/` (both still untested). Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
