Answer 1

您可以考虑使用数组节点通过 [&5] 和 [&1] 标识符循环遍历它们，例如

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "@sports.feeType": {
          "*": {
            "sport_fee_type": {
              "Discounted fee": {
                "@2,fee_details": {
                  "*": {
                    "total": "billing.feeSummary[&5].sportsCategories[&1].amount",
                    "sports_catagory": "billing.feeSummary[&5].sportsCategories[&1].sportType"
                  }
                },
                "#DISCOUNTED": "billing.feeSummary[#2].feeType"
              },
              "Non Recurring fee": {
                "@2,fee_details": {
                  "*": {
                    "total": "billing.feeSummary[&5].sportsCategories[&1].amount",
                    "sports_catagory": "billing.feeSummary[&5].sportsCategories[&1].sportType"
                  }
                },
                "#NON_RECURRING": "billing.feeSummary[#4].feeType"
              },
              "Recurring fee": {
                "@2,fee_details": {
                  "*": {
                    "total": "billing.feeSummary[&5].sportsCategories[&1].amount",
                    "sports_catagory": "billing.feeSummary[&5].sportsCategories[&1].sportType"
                  }
                },
                "#RECURRING": "billing.feeSummary[#4].feeType"
              }
            }
          }
        }
      }
    }
  },
  { // convert the values of sportType attributes to uppercase 
    "operation": "modify-overwrite-beta",
    "spec": {
      "billing": {
        "feeSummary": {
          "*": {
            "sportsCategories": {
              "*": {
                "sportType": "=toUpper"
              }
            }
          }
        }
      }
    }
  }
