I have been looking at JSONPath and though it seems pretty well done, I wonder if anyone has worked with it and can comment on its usability, or can recommend alternatives?
OK, I have created a prototype for this, available here: http://code.google.com/p/jfunk/
It has already proven useful for me, so I will probably slowly improve and refactor it into something nice. But if I get good feedback, I can move more quickly. I would also welcome help.
