I have a json as below
{
"store": {
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95,
"version": 1
},
{
"category": "reference",
"author": "Nigel Reas",
"title": "Sayings of the Decade",
"price": 8.96,
"version": 2
},
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99,
"version": 1
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99,
"version": 2
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99,
"version": 3
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
Now i want to filter the json based on two attributes.
for example: $.store.book[?((@.category,@.version) in [('fiction',2),('reference',1)])]
But above predicate is not working. Is there any way to achieve that?
The syntax you showed does not look correct. As far as I understand the JayWay implementation (yes, this comes down to the implementation details of the library), you sequentially need to combine filters using &&
and ||
like this:
$.store.book[?(@.category=='fiction' && @.version=='1' || @.category=='reference' && @.version=='2')]
First, I tried to r create a combined filter using in
, but this seems to select more values than you want:
$.store.book[?(@.category in ['fiction','reference'] && @.version in ['1','2'])]
