Re: How do I write a regex for 'does not contain' a string.

[Abigail-II]

    /^(?:[^f]+|f(?!oo))*$/;   # Matches strings not containing 'foo'.

    /^(?:(?!PATTERN).)*$/;    # Matches strings not containing PATTERN
+.

The top one is reasonably fast, the bottom one is slow, but works for all patterns.

Excelent! Thank you. I knew there must be a way to do this. Dispite the very valid points by fruiture and arturo about a better way to solve my particular problem, it was bugging me that I couldn't think of a way to do this.

With much thanks,
Ira
