Regex – how to match a line between two optional characters that are not included in group?

The regex should match

/exampleline – match exampleline

exampleline – match exampleline

exampleline/ – match exampleline

/exampleline/ – match exampleline

I tried ?/(.+)/? but it didn’t work – /exampleline/ and exampleline/ matched exampleline/, instead of exampleline

>Solution :

You can use negative lookarounds to assert that a match does not start with and does not end with a /:

(?!/).+(?<!/)
