regex: creating an exception for r:a.?b.?c

Question

I need to create a regex expression that will filter any variant of \"kitchen\" that has between 0 and 1 random characters between any of the letters, but it needs to make an ex

Answer 1

You can try using non consuming regex to make sure that "kitchen" is not covered by regex.

(?=k.?i.?t.?c.?h.?e.?n)(?=^[kitchen])

Answer 2

You can do a lookahead to make sure the string is not exactly 'kitchen'

r:(?!kitchen)k.?i.?t.?c.?h.?e.?n
