在保留分隔符的同时分割字符串

Question

any way I can split this string x+5-3+x=6+x-2 while keeping the separators, I tried regex split on [\+\-] but this gives me, x, 5, 3, ... and I need x, +5, -3, +x using (?=[-+]) as in Java doesn't work.

Thanks

use FindAllString

  regexp.MustCompile(`[-+\?=]?([0-9]|x)`).FindAllString("x+5-3+x=6+x-2", -1)
