This is an attempt to build a XPath data extractor which could be useful on handling JSON API's responses.

Given an array:
var arr = [
    {
        'foo': 'bar',
        'baz': { 'theNumber' : 42 }
    },
    {
        'foo': 'bar',
        'baz': { 'theNumber' : 84 }
    },
    {
        'foo': 'bar',
        'baz': { 'theNumber' : 168 }
    },
    {
        'foo': 'bar',
        'baz': { 'theNumber' : 336 }
    }
];

extract would be used as:

var extracted = extract('/baz/theNumber', arr);

Yielding - [ 42, 84, 168, 336 ]
