iterate over json path

[sekhar]

Hi 

Could you please let me know if it is possible to get the complete list of paths (keys) and then iterate through them to get their values one by one? 

I have a master Json document that is loaded into DocumentContext. Then I receive a child document which will have a subset of elements from master Json.  Now I have to read the child Json and update master Json data. In short, child Json data needs to be merged with master json. I am thinking of using a streaming JSON API such as Gson to read child document and then update master Json document with JSONPath.  But would like to know if this can be done using JSONpath some way, so that my application only deals with JSONpath. 

Thanks & Regards
