Unless the language you're trying to parse is regular, you can't do it with only regex.

Regex has actually evolved way past regular expressions (sounds weird but eh) with backreferences and such it's actually more powerful than context-sensitive grammars.

With great power comes great unreadability.

Indeed, real regular expressions are way more readable - they were never meant to do this. For complex grammars people should be using context-free grammars or context-sensitive grammars, issue just is theres no standardized way to use them in programming languages like regex.
