JSONPath：保留过滤值的内容

Question

以下是我试图提取匹配过滤器内容的JSON内容

{
        "results": [{
                "individualProviderId": "P1",
                "locations": [{
                        "addressInfo": {

                        ]
                    }

                ]
            }
        ],
        "status": "OK"
    }

JSONPath表达式：$ ..分层[？（@。policyPlanID ==＆＃39; PP1＆＃39;）]）

匹配值

[
   {
      "policyPlanID" : "PP1"
   },
   {
      "policyPlanID" : "PP1"
   },
   {
      "policyPlanID" : "PP1"
   }
]

问题是有没有API来保护根级别的整个JSON结果的内容？ 是否有任何特定的API来获取Paths的结果

[
   "$['results'][0]['locations'][0]['plans'][0]['tiering'][0]",
   "$['results'][0]['locations'][0]['plans'][2]['tiering'][0]",
   "$['results'][1]['locations'][0]['plans'][1]['tiering'][0]"
]
