Get specific object from JSONPath array result after predicate is applied - arrays

Question

In JSONPath 0.9.1 the following Json path was valid:
http://jsonpath.herokuapp.com/?path=$.store.book[?(#.author==%27Nigel%20Rees%27)][0]
returning
{
"category" : "reference",
"author" : "Nigel Rees",
"title" : "Sayings of the Century",
"price" : 8.95
}
I've upgraded to the latest one (2.3) and the query now returns empty array.
Is this a bug or the way to retrieve an element from the resulting array has changed?

Answer 1

Given this document:
{
"store": {
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
Using JsonPath 2.3.0, the following code returns a JSONArray (rather than an Object[]):
JsonPath.parse(JSON).read("$.store.book[?(#.author==\"Nigel Rees\")]");
So, the following code ...
JSONArray read = JsonPath.parse(JSON).read("$.store.book[?(#.author==\"Nigel Rees\")]");
System.out.println(read.get(0));
... will print:
{category=reference, author=Nigel Rees, title=Sayings of the Century, price=8.95}
