We wrote something quite similar for Bouygues Telecom and based it on an ANTLR grammar [2].

It offers nested filtering out of the box. All feature-packed in a lightweight package.

This looks excellent. It’s just missing some documentation on usage, otherwise, I’d actually have an immediate use case for it!
