Re^2: RegEx - match pattern not followed by literal

I think your negative look-ahead needs to be something like (?!.*,v$) because you don't know where the user-supplied regex is going to leave off matching. I agree with Fletch, however, as the optimisation game is probably not worth the candle.

Cheers,

I don't think a negative look ahead will work - .(?!,v) will still match foo,v* since the .* can just suck up the ,v Tom Melly, tom@tomandlu.co.uk	[reply]

Yes, perhaps that needs to be non-greedy like `(?!.?,v$)` but note that the `.?` is inside the assertion. Cheers, JohnGG	[reply] [d/l] [select]
