Regex to match anything but two words

Question

I\'m trying to write a regular expression to match anything that isn\'t \"foo\" and \"bar\". I found how to match anything but one word at Regular expression to match a lin

Answer 1

Answer to the question: "How to add a second word to this critera?"

The answer of the question you link to is:

^((?!word).)*$

Where (?!word) is a negative look-ahead. The answer for this question is:

^((?!wordone|wordtwo).)*$

Works for both words. Note: you should enable the global and multiline options, if you have multiple lines and want to match for each line, as the other question.

The difference is the negative look-ahead clause: (?!wordone|wordtwo). It can be extended to any (reasonable) amount of words or clauses.
