How to identify location of key in json?

Hello,

I wonder if there is simple way... I am communicating with web server which returns data as json. json xop is amazing and makes it trivial to get data into Igor...  The problem is, that depending on how I ask the question, data (identified by specific keys) of interest may be located in different "levels" of complicated nested structure. I would love to be able to find location of specific keys instead of programming all the different structures I can get. Basically, key "title" will always have what I want independently where it is located. 

I can traverse the structure and get all keys on each level using json_GetKeys until I find the keys of interest. I know how to do that. But I wonder if I am missing some easier method. My reading of json xop manual did not show anything which would return location of specific key. 

Thanks!
