Create XML from JSON

I have a JSON-file, which I want to convert to XML in JAVA to process some different things with the outcoming XML-structure. My file looks like this:

{
    "published" : "2014-04-15T12:00:13.760Z",
    "actor" : {
        "objectType" : "person",
        "id" : "a00906a9-d3e3-40b5-8ef2-9e1051828c09",
        "displayName" : "Ashley Wessels"
    },
    "verb" : "floating_run",
    "object" : {
        "objectType" : "experiments",
        "id" : "e9d9f71a-6c9e-4724-98d1-32dee57bb015",
        "content" : [
            {
                "mass" : 10,
                "volume" : 392.2,
                "density" : 0.025497195308516064,
                "fluid" : 1
            },
            {
                "mass" : 150,
                "volume" : 150,
                "density" : 1,
                "fluid" : 1
            },
            {
                "mass" : 50,
                "volume" : 50,
                "density" : 1,
                "fluid" : 1
            },
            {
            "mass" : 50,
            "volume" : 100,
            "density" : 0.5,
            "fluid" : 1
            },
            {
            "mass" : 100,
            "volume" : 50,
            "density" : 2,
            "fluid" : 1
            },
            {
            "mass" : 400,
            "volume" : 300,
            "density" : 1.3333333333333333,
            "fluid" : 1
            }
        ]
    },
    "target" : {
        "objectType" : "experiment",
        "id" : "9383fbbe-e071-49b2-9770-46ddc4f8cd6e",

}

I used the org.json library and also tried some other libraries like JETTISON to create a xml-file from this guy but most of the `XML.toString()" methodd are not able to handle the JSONArray in this file. It just produces weird output of quotations marks etc. Is there a library which can handle this type of JSON structure? If not: how should I handle this file type?
