How do I tell a regular expression to not match a group?

Question

I experimented with regular expression in the learning process.

Input: I am ironman and I was batman and I will be superman

I want to combine all the words except the word batman

I tried [^(batman)]+, but it does not match the characters a,b,m,n,tanywhere in the string

How can i achieve this?

Answer 1

Several ways are possible:

with a negative statement (?!...)(not accompanied):

\b(?!batman\b)\w+

with capture group (you should only consider capture group 1):

\b(?:batman\b|(\w+))

Why your template does not work:

You wrote [^(batman)], but a character class is just a set of characters without order, you cannot describe substrings inside it. This is the same as[^abmnt()]
