I know it is quite some weird goal here but for a quick and dirty fix for one of our system we do need to not filter any input and let the corruption go into the system.
My current regex for this is “\^.*“
The problem with that is that it does not match characters as planned … but for one match it does work. The string that make it not work is ^@jj (basically anything that has ^ … ).
What would be the best way to not match any characters now ? I was thinking of removing the \ but only doing this will transform the “not” into a “start with” …
The
^character doesn’t mean “not” except inside a character class ([]). If you want to not match anything, you could use a negative lookahead that matches anything:(?!.*).
