complement of \ with regular expression
I am testing my regular expression and I am getting a bit confused from my understanding  is used to indicate a set of characters ^ is the complement. So [^a] would be a set of any characters excluding a I am having trouble with this particular bit of regular expression [^\] This excludes the character set \ I tried testing this on an online regular expression tester with the string a\d\c\e\d but no results would display. I feel that I might be missing something but I am not sure what that could be.
Backslash is the escape character in regular expressions. To refer to it literally, you have to escape it: [^\\]
