There are a variety of suitable XPath-like libraries for JSON. It wouldn't be hard to implement user-defined functions (and virtual tables) to use such a library. It'd have to encode/parse JSON texts all the time when interfacing with SQLite3, which is a bit suboptimal. Something could be done to improve that, but it'd be an optimization. The only thing SQLite3 really needs here is a way to index on expressions, but even this can be worked around with triggers (at some cost).
