Question

I am somewhat confused right now with a obviously pretty simple regex but it must be the lack of caffein or the weather today. Basically what I have is a string that can be something like ‘sw’ or ‘ee’ or ‘n.a.’.

Now what I want & need is a regex.match that gives me back ” in case the provided string is ‘n.a.’, in all other cases I want ‘_’ (underscore + the original value). Is that possible?

Answer 1

The following regex will only mstch your non ‘n.a’ string values.

^(?!n\.a).*
