How to parse multi dimension array into Talend

I have array which I need to parse into Talent

{
    "sEcho": 1,
    "iTotalRecords": 54,
    "iTotalDisplayRecords": 54,
    "aaData": [
        [
            "79",
            "testowy2",
            "testowy samochod",
            "12.00",
            "14.00",
            "2147483647",
            "posciel",
            ""
        ]
    ]
}

What would be Xpath Query which I need to pass on the tExtractJSONFields ?
