regex - How do I make this regular expression not match anything after forward slash /

Question

I have this regular expression:

/^www.example.(com|co(.(in|uk))?|net|us|me)/?(.*)?[^/]$/g

It matches:

www.example.com/example1/something

But doesn't match

www.example.com/example1/something/

But the problem is that, it matches: I do not want it to match:

www.example.com/example1/something/otherstuff

I just want it to stop when a slash is enountered after "something". If there is no slash after "something", it should continue matching any character, except line breaks.

I am a new learner for regex. So, I get confused easily with those characters

You can use

^www.example.(?:com|co(?:.(?:in|uk))?|net|us|me)/([^/]+)/([^/]+)$

See the regex demo

The (.*)? part in your pattern matches any zero or more chars, so it won't stop even after encountering two slashes. The /([^/]+)/([^/]+) part in the new pattern will match two parts after slash, and capture each part into a separate group (in case you need to access those values).

Details:

• ^ - start of string
• www.example. - www.example. string
• (?:com|co(?:.(?:in|uk))?|net|us|me) - com, co.in, co.uk, co, net, us, me strings
• / - a / char
• ([^/]+) - Group 1: one or more chars other than /
• / - a / char
• ([^/]+) - Group 2: one or more chars other than /
• $ - end of string.
