How to reference a key/value pair from JSON of different structure

Hi,

Please, is there a way to reference a key part of JSON file that can come in different structures.

For example i want to get the value of "requestUid" from these different JSON structures just with a single processor. So, irrespective of JSON formats or structures sent, i would want to get the value of requestUid.

Thanks.

For example:

1)

{
"responseMetaData": {
"type": "ACK",
"userId": "SYSTEM",
"requestUid": "1742963e-f02f-4db6-88e0-6af8c4d4825b",,
"systemId": "CIF",
"serviceId": "FR_CUS"
},
"responseDataObject": {
"result": "Accepted",
"responseCode": "SUC",
"responseMessage": "",
"execTime": "1216"
}
} 

2)

{
"responseMetaData": {
"type": "ACK",
"sendTime": "23/03/2019 09:16:25.305277",
"timeZone": "4",
"userId": "SYSTEM",
"branchCompanyId": "784100",
"branchLocationId": "784101",
"systemId": "CIF",
"serviceId": "FR_CUS"
},
"responseDataObject": {
"result": "Accepted",
"responseCode": "SUC",

"requestUid": "yywhhnan56289200200",
"execTime": "1216"
}
}
