Regex to include the string values not substring values

Question

I have the following string:

name:ABC;

username:XYZ;

I want to remove the name value ABC from the string, so I am using the following regex:

((?<=name))(.*?)(?=;)

It successfully selects the name value, but the problem is it also selects the username value.

I want to remove only the name values not username values.
How can I do that?

SOLUTION:

**Both Avinash and Bohemian answer's are correct for this question. By Avinash answer we can exclude all the words contains name as substring and with Bohemian answer we can exclude specific words.

Answer 1

Modifying your regex, you can combine two look behinds, one positive, one negative:

(?<!username)(?<=name).*?(?=;)

Note also the removal of unnecessary brackets.

Avinash's answer is probably what I would use in this case, but I thought I would show this way in case \b didn't work for future visitors, eg all data whose name ends in name (streetname, cityname, etc) except username.

Answer 2

Use word boundary \b before name.

(?<=\bname:)(.*?)(?=;)

or

(?<=\bname:)[^;]*
