Parsing Dynamic JSON Keys in Nested JSON Results
Question:
How to access the content of keys that are dynamic values within a JSON result?
Sample JSON:
{ "status": "OK", "search_result": [ { "product": "abc", "id": "1132", "question_mark": { "141": { "count": "141", "more_description": "this is abc", "seq": "2" }, "8911": { "count": "8911", "more_desc": "this is cup", "seq": "1" } }, "name": "some name", "description": "This is some product" }, { "product": "XYZ", "id": "1129", "question_mark": { "379": { "count": "379", "more_desc": "this is xyz", "seq": "5" }, "845": { "count": "845", "more_desc": "this is table", "seq": "6" }, "12383": { "count": "12383", "more_desc": "Jumbo", "seq": "4" }, "257258": { "count": "257258", "more_desc": "large", "seq": "1" } }, "name": "some other name", "description": "this is some other product" } ] }
Solution:
To access dynamic keys in a nested JSON result, use the keys() method of the JSONObject class. This method returns an Iterator that can be used to iterate over the keys in the object. Once you have the keys, you can use the getJSONObject(key) method to retrieve the corresponding values.
Here is an example of how to parse the dynamic keys in the example JSON:
JSONObject searchResult = ...; // Assuming searchResult is a JSONObject JSONObject questionMark = searchResult.getJSONObject("question_mark"); Iterator keys = questionMark.keys(); while (keys.hasNext()) { String currentDynamicKey = (String) keys.next(); JSONObject currentDynamicValue = questionMark.getJSONObject(currentDynamicKey); // Do something with the dynamic key and value... }
This code iterates over the keys in the question_mark object and retrieves the corresponding values. You can then use these values to access the data you need.
