regex match one string only if line does not contain another string -



regex match one string only if line does not contain another string -

is there general regex matching 1 string, if line not contain string?

e.g want match word apple if line not contain banana. next lines:

apple banana - not match pear apple - matches apple not pear apple pear apple - matches first , sec apple not pear

i know

^((?!banana).)*$

will match line not contain banana. can't seem combine matching apple only.

you can utilize pcre regex:

.*banana.*$(*skip)(*f)|\bapple\b working demo

regex
