Parse JSON in Java
java, json
Solution
For `JSON` equivalent of `XPATH for XML` you can use `JsonPath`
As per docs:
`JsonPath` is to `JSON` what `XPATH` is to `XML`, a simple way to extract parts of a given document. `JsonPath` is available in many programming languages such as `Javascript`, `Python` and `PHP`. Now also in Java!
Problem
I am currently working with Java, reading JSON response from a webservice. Till now I have been parsing JSON for a path known in advance. So I am able to make objects and arrays depending on situation. ``` String jsonText = readAll(br); JSONObject json = new JSONObject(jsonText); JSONObject resp = json.getJSONObject("Response"); ``` But now I have a problem. I have to ask user to provide me a path and I have to get the value at that path in JSON response. Path could be incorrect - return error in that case. Kind of like XPath in XML. Do we have something similar in JSON? Path could for example look like: /Response/VehicleSearch/Vehicles/Vehicle[2]/Features/Feature[7]/ID Please excuse me if its a stupid question. Any help is appreciated. Thanks in advance.
