Javascript regex: match any character that is not in the set of symbols (but only if this symbol doesn't follow a backslash)

Question

I need a regex which matches any character that is not in the set of symbols (but only if this symbol doesn't follow a backslash)

Is there any one line solution?

sample input: "Test1\,test2,test3\<\>test4<>test5"
reqex to improve: /[^,<>]+/

expected output:

Answer 1

Assuming \ is not at the first position of a match you may use this regex:

[^,<>\\]+(?:\\.[^,<>\\]*)*

RegEx Details:

• [^,<>\\]+ : Match 1 or more of any character that are not inside the the [...]
• \\. match any escaped character

If \ can be at first position then you may use:

(?:\\.|[^,<>\\]+)+
