Have you considered wrapping the code into a parse transform so you
can "embed" the javascript notation into Erlang directly?

Another option is to write an xpath-like query tool, perhaps with a
Zipper construction on the parse tree so you have a neat continuation
for the next match, should you need it. This is probably my solution,
if I need to process JSON documents in the future. You already made
the first venture into this - think jQuery DOM selectors on steroids
for selection into JSON structures.
