More JSON handling routines in LMS builds?

Philippe's recent post about Crypto reminded me of this.

I'd like something that would allow me to specify json in a similar way
to how XPath does for XML.
I think this would allow me to remove code I have that checks for
certain elements being present in a received JSON document and instead
move it out to a configuration file that checks an XPath-like
definition.

In my messy code I have a bunch of if/then/else statements testing the
received json from various radio stations to determine which format it
is in so that I can subsequently parse it correctly.
I have made the subsequent parsing code simpler than it used to be by
having song & programme field names in a config file per station group.

I could put real Perl code in the config files and then eval it but I
don't think that is a good way of doing things.

If I could put a XPath like statement in there as well then I could
simplify things further.

Perhaps JSON::Path ... it looks to me like it has a lot of dependencies
that are currently not met in standard LMS installation and I think some
are not pure Perl so would mean compiling and packaging binaries for the
various platforms which is something I don't really want to get into.
