There's an input of strings that are composed of only digits, i.e., integer numbers. How can I write a regular expression that will accept all the numbers except numbers 1, 2 and 25?
I want to use this inside the record identification of BeanIO (which supports regular expressions) to skip some records that have specific values.
I reach this point ^(1|2|25)$, but I wanted the opposite of what this matches.
Not that a regex is the best tool for this, but if you insist...
Use a negative lookahead:
/^(?!(?:1|2|25)$)\d+/
