What I have tried so far is like this:
final JSONArray jsonMainArr = locationData.getJSONArray("resourceSets").getJSONObject(0).getJSONArray("resources");
final JSONObject childJSONObject = jsonMainArr.getJSONObject(0);
return childJSONObject.getString("formattedAddress");
childJSONObject is still 2-3 levels over formattedAddress and the query is becoming highly inefficient
get formattedAddress address value as from current json String :
final JSONObject childJSONObject = jsonMainArr.getJSONObject(0)
.getJSONObject("address");
return childJSONObject.getString("++formattedAddress++");
There are so much online sites where you paste your complex code and get it in an easy way. e.g. http://json.parser.online.fr/

I am using jsonpath to filter.
Json(Dummy json just to explain) source String, which is basically a list of Operating systems and details of its programs etc. In this example, the OS whose id = 1403 is a windows 10 OS and has 2 features acchritecture and browser. There are more details to the browser feature as shown in json
[

"id": 1403,
"os": "window 10",

I want to be able to filter the json such that
features[*].name == 'browser' and features[*].value[*].feature[*].value == 'chrome'
What will be the JsonPath string that can help me achieve above query? The above query uses similar syntax used by JsonPath string but doesn't do the job. Its just to explain.
There is another example here gets Movie Title Given 'Starring' field
And would like to get the full OS json that fulfils this condition. In this case a array of OS which contains only one OS i.e. with id= 2804
[
{
"id": "2804",
...
}
]
I am stuck much before what aim to achieve. Here is my code to get all the OS that have "name=browser". I get the array but it only contains value[] items. I want it get the full json. It returns object with IDs- 1357, 2765.
List<Map<String, Object>> expensive = JsonPath.parse(jsonDataSourceString)
.read("$[*].features[*].[?(#.name == 'browser')]");
To get the outer array you need to use the filter like $[?(...)]
For your current use case, we need to use nested array filters. There is an open issue in JsonPath for filter on children level. (Refer here).
Luckily, there is a workaround suggested to use contains over here.
we can use the below expression to filter:
List<Object> expensive = JsonPath.parse(jsonDataSourceString)
.read("$[?(#.features[?(#.name == 'browser')].value[*].feature[*].value contains 'Chrome')]");
Prints the below output
{id=2804, os=window 7, features=[{"id":2764,"name":"architecture","value":[{"id":2719,"feature":[{"id":2679,"key":"name","value":"amd64"}]}],"category":"cat1"},{"id":2765,"name":"browser","value":[{"id":2722,"feature":[{"id":2685,"key":"name","value":"Chrome"},{"id":2684,"key":"version","value":"87.0.4280.88"}]}],"category":"cat2"}]}

I am trying to save the values for CoachID (3028), IgpID(1872), IgpId(1911), IgpName(Dr. heath), IgpNAME(Dr Jc crook) in String variables in APex class.
I have used a map to do so but unable to get the proper values. I wanted to get the above values in a List & return that list from function.
Can anyone help me on this? I am not supposed to do this using wrapper.
Regards,
Mohit
It can't be done as straight "JSON.deserialize" call because some fields are reserved keywords in Apex. How strict the wrapper ban is? I wouldn't want to type this stuff freehand but you can go to https://json2apex.herokuapp.com/, tick checkbox about explicit parser (again, since you have reserved keywords it'd happen anyway) and well, you have a ready class & cool stab at unit test / example how to use the code. It's battle-tested, if you can't use that then your project has bigger problems ;)
If you really really have to do it alone and with maps it'll be something like https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_class_System_Json.htm, example for deserializeUntyped

I want to load three attributes into my table ( id, actions_name and actions_link). So, in the first step (tFileInputJSON) - I tried to do a Loop Json query as below:
Here, am able to extract the rows as I needed. But, then I used a tExtractJSONField to extract individual fields under "actions" for each "id" using XPath expressions as below:
I tried several other ways to extract the fields but could not do this. Also, not able to find any correct post in stack overflow and talent forums very relevant to my question. Could somebody please help?
Arrange the job like ,
tFileInputJSON is like,
tExtractJSONFields is like,
Then you will get output as,
Very new to JSON. Using json-lib for this and been pulling my hair out trying to get "definitions" from this JSON response by Oxford Dictionaries API. Tried all sorts of things. But can never get anything more specific than everything from "results". Would like to figure out why this is so difficult otherwise will just resort to regex.
JSONObject obj = new JSONObject(stringBuilder.toString());
JSONArray arr = obj.getJSONArray("results");
String test = arr.getJSONObject(1).toString(); // Empty wtf?
String definition = obj.getString("definitions"); // empty also...
Managed to also access "id", "language" and "lexicalEntries" separately, but anything beyond that doesn't seem to want to cooperate.... Is this a normal JSON response? It's quite awkward no? Thanks...

Watch carefully the way we traverse the JSON object and when we should use getJSONObject & getJSONArray methods to retrieve the particular type of data we want from JSON Object.
Update: You might want to iterate the JSON array as per your requirement. I have just explained the case as in how to reach till definitions.
I have the following json string. Sometimes, there are multiple definition elements and sometimes there is only one. I am new to JSON parsing and I somehow, in a very primitive way, managed to get the value of the first definition element that occurs. However, I am unable to get all values of definitions since there is no resource that I can find online. Do I have to check if second occurrence exists or is there a better way to do it ?

Java snippet to get definition value:
String locations = data.getJSONArray("results").getJSONObject(0).getJSONArray("lexicalEntries").getJSONObject(0).getJSONArray("entries").getJSONObject(0).getJSONArray("senses").getJSONObject(0).get("definitions").toString();
Everything looks good but you should stop at getJSONArray("senses").
It should be
JSONArray senses= .....getJSONArray("senses");
and then you should loop thru elements of that array. Something like this.
ArrayList<String> definitions = new ArrayList<String>();
for(int i =0; i < senses.length(); i++){
definitions.add(senses.getJSONObject(i).optString("definitions","");
}
But before doing that you should notice that your definitions json is not well formed it should be someting like
"definitions":"blablabl blablab"
Since it is not an array;.
