JSONPath pattern - keeping object structure - json

Question

I'm having a bit of trouble doing something with JSONPath. This is what I have:
[
{
"id": {
"type": "literal",
"value": "123456789",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
},
"name": {
"type": "literal",
"value": "John Doe",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
}
},
{
"id": {
"type": "literal",
"value": "2123456789",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
},
"name": {
"type": "literal",
"value": "Jane Doe",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
}
}
]
}
]
And what I would like to get after applying a pattern is:
[
{
"id": "123456789",
"name": "John Doe"
},
{
"id": "2123456789",
"name": "Jane Doe"
}
]
Is this possible? The best I am doing is ["123456789", "John Doe","2123456789","Jane Doe"]
How should the pattern look like?

With DefiantJS (http://defianjs.com), you can query JSON structure using XPath expressions. DefiantJS extends the global object JSON with the method "search" and it returns matches as an array-like object.
Here is an example code;
var data = [
{
"id": {
"type": "literal",
"value": "123456789",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
},
"name": {
"type": "literal",
"value": "John Doe",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
}
},
{
"id": {
"type": "literal",
"value": "2123456789",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
},
"name": {
"type": "literal",
"value": "Jane Doe",
"datatype": "http://www.w3.org/2001/XMLSchema#string"
}
}
],
found = JSON.search(data, '//value'),
str = '';
for (var i=0; i<found.length; i++) {
str += found[i] +'<br/>';
}
document.getElementById('output').innerHTML = str;
