Select Nth item from filter expression in JSONPath
I am trying to filter a specific element in my JSON using JSONPath and then select only the 1st element in the returned result array.
My baisc JSONPath looks something like this:
$.store.book[?(@.category==fiction)].price
I want to add this filter [0]
like this:
$.store.book[?(@.category==fiction)][0].price
but it returns no results, or if I put [0]
after the last "price" I get this error:
Filter: [0] ['price'] can only be applied to arrays
I searched and couldn't find the correct syntax to pull the 1st element in the array after applying the filter as in xpath.
This is the basic JSON I'm working on:
{ "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
}
}
}

what about when you want to use jsonpath with spring mvc i got it
.andExpect(jsonPath("$[?(@.name.value == 'Item')].depth", is(Collections.singletonList(2))))
instead
.andExpect(jsonPath("$[?(@.name.value == 'Item')][0].depth", is(2)))
which by the way was used for older versions (0.9.1) for me
