How would I construct regex so I can perform replacements like these:
abcdef[Backspace][Backspace][Backspace] -> abc[Backspace][Backspace] -> (empty string)Currently, I’m trying to replace backspaces one-by-one in a loop. Is there another way?
Just for the sake of completeness, here is a solution using a negative lookbehind (the one that you probably intended to use yourself):
And replace with an empty string. Do this in a loop. If you are using Java or there are some other circumstances that require escaping of backslashes, double the two backslashes.
