 Author: xanuex [ Thu Oct 01, 2015 2:17 am ] Post subject: Regex min/max length combined with other expressions I'm working on a Regex which has the following limitations;1. No punctuations but a dash2. No numbers only characters3. First letter should be uppercase4. Minimal 3 characters5. Maximal 12 charactersExcept for nr. 4/5 this has the required result.^[A-Z][a-z]+(-[A-Z][a-z]+)?\$For the last part I've tried the following but it's not working correctly. Who can help me figure this out?^([A-Z][a-z]+(-[A-Z][a-z]+)?){2,12}\$See alsohttps://www.debuggex.com/r/JIyOwvdYdO0WgrwI

 Author: requinix [ Thu Oct 01, 2015 2:45 am ] Post subject: Re: Regex min/max length combined with other expressions If you only had one part with a quantifier (+) then it would be easy: it's 3-12 minus the number of required characters. I think that's what you were trying to go for, but (1) it doesn't account for how the first [a-z]+ has an unknown length and (2) the {2,12} will try to repeat the entire expression.If you absolutely must use a regular expression for it, use a positive lookahead at the beginning of the string.Code:^(?=.{3,12}\$)[A-Z][a-z]+(-[A-Z][a-z]+)?\$"At this point there must be 3-12 characters and then the end of the string". The rest of the regex deals with the character restrictions.Naturally, if you do not absolutely need a regular expression then strlen() is the way to go.
