JsonPath - Restrict To Research to One level - json-path-expression

Question

I am just trying JsonPath. It's great but I have a problem with a special case. I searched here but could not find a solution.
So, my JSON file is below:
[
{
"id": 1,
"images": [
{ "id": 1,"url": "http://url1.jpg" },
{ "id": 2,"url": "http://url2.jpg" }
]
},
{
"id": 2,
"images": [
{ "id": 1,"url": "http://url3.jpg" },
{ "id": 2,"url": "http://url4.jpg" }
]
},
{
"id": 3,
"images": [
{ "id": 1,"url": "http://url5.jpg" },
{ "id": 2,"url": "http://url6.jpg" }
]
}
]
With this expression $.[?(#.id=='2')], the result is
[
{
"id": 2,
"images": [
{
"id": 1,
"url": "http://url3.jpg"
},
{
"id": 2,
"url": "http://url4.jpg"
}
]
},
{
"id": 2,
"url": "http://url2.jpg"
},
{
"id": 2,
"url": "http://url4.jpg"
},
{
"id": 2,
"url": "http://url6.jpg"
}
]
But I need to restrict my query result to one level without the children. The last 3 elements are not necessary. I need only the first element.
{
"id": 2,
"images": [
{
"id": 1,
"url": "http://url3.jpg"
},
{
"id": 2,
"url": "http://url4.jpg"
}
]
}

As hinted in my comment, there are subtle differences in the implementation of the various JSONPath libraries. The same syntax may or may not produce the same result depending on the library at hand.
Nonetheless, we can adjust your query to make it work as expected by dropping the dot after the root symbol:
$[?(#.id===2)]
Note: I have tested the path above using Goessner's JavaScript implementation; the C# equivalent should look like this: $[?(#.id==2)].
