Conditional based on a input field

[dmasoft]

Hi!
I'm trying to create a spec files that writes a concrete array from the input file based on the value of another field of the input json.
This is the input file:

{
 "addressBook": {
    "primaryAddress": "pxD",
    "addresses": [
      {
        "id": "pxD",
        "fullName": "Daniel Garcia",
        "street": "Berenguer",
        "houseNumber": "234",
        "houseName": "",
        "floorNo": "",
        "streetType": "Str",
        "doorNo": "",
        "postOfficeBox": "",
        "city": "Barcelona",
        "zipCode": "08812",
        "state": "",
        "province": "",
        "addressLine1": "",
        "addressLine2": "",
        "addressLine3": "",
        "countryCode": "ES"
      },
      {
        "id": "pxDss",
            "fullName": "Daniel Garcia",
        "street": "Berenguer",
        "houseNumber": "234",
        "houseName": "",
        "floorNo": "",
        "streetType": "Str",
        "doorNo": "",
        "postOfficeBox": "",
        "city": "Barcelona",
        "zipCode": "08812",
        "state": "",
        "province": "",
        "addressLine1": "",
        "addressLine2": "",
        "addressLine3": "",
        "countryCode": "ES"

      }
    ]
}
  }

The ouput file should contains the address that has the same id value than the primaryAddress field value. In case there is not a primaryAddres field, the first address should be written to the output.
Desired output file:

{
"address" : {
    "id" : "pxD",
       "fullName": "Daniel Garcia",
        "street": "Berenguer",
        "houseNumber": "234",
        "houseName": "",
        "floorNo": "",
        "streetType": "Str",
        "doorNo": "",
        "postOfficeBox": "",
        "city": "Barcelona",
        "zipCode": "08812",
        "state": "",
        "province": "",
        "addressLine1": "",
        "addressLine2": "",
        "addressLine3": "",
        "countryCode": "ES"
  }
}

Thanks!

Hi dmasoft, This may be helpful for you.

[
  {
    "operation": "default",
    "spec": {
      "addressBook": {
        "primaryAddress": ""
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "addressBook": {
        "primaryAddress": "addressBook.primaryAddress",
        "addresses": {
          "*": "addressBook.addresses.@(2,primaryAddress)"
        }
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "addressBook": {
        "primaryAddress": {
          "": {
            "@(2,addresses)": {
              "": {
                "0": "address[]"
              }
            }
          }
        },
        "addresses": {
          "*": {
            "*": {
              "id": {
                "&2": {
                  "@2": "address[]"
                }
              }
            }
          }
        }
      }
    }
  }
]

And you didn't point out how to handle it if more than one have the same id value than the primaryAddress field value. Let's say you only need one,this may help you

[
  {
    "operation": "default",
    "spec": {
      "addressBook": {
        "primaryAddress": ""
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "addressBook": {
        "primaryAddress": "addressBook.primaryAddress",
        "addresses": {
          "*": "addressBook.addresses.@(2,primaryAddress)"
        }
      }
    }
  },
  {
    "operation": "shift",
    "spec": {
      "addressBook": {
        "primaryAddress": {
          "": {
            "@(2,addresses)": {
              "": {
                "0": "address[]"
              }
            }
          }
        },
        "addresses": {
          "*": {
            "*": {
              "id": {
                "&2": {
                  "@2": "address[]"
                }
              }
            }
          }
        }
      }
    }
  }, {
    "operation": "cardinality",
    "spec": {
      "address": "ONE"
    }
  }
  }
]
