Get list of string from list of Json object

Question

I am trying to extract list of string from following Json

"example":{[
{"@name":"name1"},
{"@name":"name2"},
{"@name":"name3"},
{"@name":"name4"}
]}

I want to get the list of @name values. I am using jayway jsonpath to do this.

I tried the following code,

List<String> response = null;
    try{
      ReadContext ctx = JsonPath.parse(data);
      response = ctx.read(xPath);
    }catch(Exception e){
      AppLogger.EventLogger.error(e.getMessage());
      response = null;
    }
    return response;

but got an exception saying could not find the specified path. I have used the following jsonPath example.@name

Can someone tell me What went wrong in my code? how to extract list @name values.

Expected output :

[name1,name2,name3,name4]

Answer 1

I have made small changes to your json in order to make it valid.

{"example":[
{"@name":"name1"},
{"@name":"name2"},
{"@name":"name3"},
{"@name":"name4"}
]}

and the code which specified works perfectly fine with the following expression: $.example[*].@name

There are a lot of online services which can help validate your json. One of them is jsonlint.com

I would also recommend to look at json.org.
