i am trying to match all not-words except ";;;" in a string, but i don't succeed. The not-words are unknown beforehand. Please see an example as follows:
Teststring:
ab-cd ef;;;gh;ij;;;
Result:
abcdef;;;ghij;;;
Does anybody know a smart solution for that?
Thank you very much!

You can use the following regex to get all the parts of the string, you want to keep:
/w+(?:;{3})?/g
It matches any number of Word chars, followed by a non capturing Group matching 3 semi colons. This is optional.
You can then create the result by joining all the matches to a string.

Thank you. Can you think of a way to match all the W characters (except ;;;) in order to replace them?

Here you get 'what you want', not 'what you don't want', so Theres nothing that should be replaced.
