Question

I have regular expression which is checking for at least one character or number:

^(?=.*[a-zA-Z])(?=.*[0-9]).*$

I want to add one more condition there to exclude forward slash:

I know that to exclude forward slash would be something like that [^/] but i don’t know how exactly put it to my regex.

May be someone may help me with that?

Answer 1

^(?=.*[a-zA-Z])(?=.*[0-9])[^/]*$

That’s all there is to it.

The dot . means “any character”. The * repeats the previous token 0 or more times. So

[^/]*

means “zero or more non-slash characters”, whereas

[^/].*

means “one non-slash character, followed by zero or more characters of any kind”.
