Match everything outside of two strings

For an input of

*something here*another stuff here

I want to match everything that's outside of the two asterisk (*).

Expected output after regex:

another stuff here

I figured out how to match everything inside of the (*) /(?<=\*)(.*)(?=\*)/ but I can't match everything outside. Noticed that I don't wish to match the *.

You can remove substring(s) between asterisks and trim the string after:

s.replace(/\*[^*]*\*/g, '').trim()
s.replace(/\*.*?\*/g, '').trim()

See the regex demo.

Details

  • \* - an asterisk
  • [^*]* - any zero or more chars other than an asterisk
  • .*? - any zero or more chars other than line break chars, as few as possible (NOTE: if you use .*, you will get an unexpected output in case when the string has multiple substrings between asterisks)
  • \* - an asterisk

See a JavaScript demo:

console.log("*something here*another stuff here".replace(/\*[^*]*\*/g, '').trim())
// => another stuff here

You can split the string with * anything * and then join the string to get the result.

const mystring = "*something here*another stuff here";

const result = mystring.split(/[*].*[*]/).join("");
console.log(result);
