javascript - 遍历json节点

Question

是否可以遍历所有节点，从一个级别未预先确定的复杂json中找到想要的字段

{
    "_index": "test",
    "_type": "news",
    "_source": {
        "partnerName": "propertyFile 9",
        "relatedSources": "null",
        "entityCount": "50",
        "Categories": {
            "Types": {
                "Events": [{
                    "count": 1,
                    "term": "Time",
                    "Time": [{
                        "term": "Dec 9",
                        "Dec_9": [{
                            "count": 1,
                            "term": "2012"
                        }]
                        }]
                    }, {
                    "count": 4,
                    "term": "News",
                    "News": [{
                        "term": "Germany",
                        "Germany": [{
                            "count": 1,
                            "term": "Election"
                        }],
                        "currency": "Euro (EUR)"
                    }, {
                        "term": "Egypt",
                        "Egypt": [{
                            "count": 1,
                            "term": "Revolution"
                        }]
                        }]
                    }]
                }
        }
    }
}

我可以进入第一级，但是如果第一级中不存在字段名称，我如何进入第二级。我就是这样开始的。 http://jsfiddle.net/W8qhA/1/
