If you are implementing it in a functional and GC language (like OCaml, Scheme/Clojure, JavaScript, F#, Elm, Haskell) using parser combinators is a lovely technique where you make composable mini-parsers. Worth researching! As a side effect (hehe) you’ll learn how to simulate state in a pure language... Enjoy
