[regex] What regex will match every character except comma ',' or semi-colon ';'?

Is it possible to define a regex which will match every character except a certain defined character or set of characters?

Basically, I wanted to split a string by either comma (,) or semi-colon (;). So I was thinking of doing it with a regex which would match everything until it encountered a comma or a semi-colon.

Use this:

([^,;]*[,;])*

use a negative character class:

[^,;]+

Use character classes. A character class beginning with caret will match anything not in the class.

[^,;]
