如何從postman中的json數組中獲取元素？

Question

此代碼找到第一個元素：

var jsonObject = xml2Json(responseBody);
pm.collectionVariables.set("VehicleVisit",jsonObject['soap:Envelope']['soap:Body'].findVehicleVisitsResponse.findVehicleVisitsResult.allVehicleVisits.WS_VehicleVisit[0].visitNumber);

這段代碼找到最后一個元素：

var jsonObject = xml2Json(responseBody),
    vehicleVisitArray = jsonObject['soap:Envelope']['soap:Body'].findVehicleVisitsResponse.findVehicleVisitsResult.allVehicleVisits.WS_VehicleVisit;

pm.collectionVariables.set("VehicleVisit", vehicleVisitArray[vehicleVisitArray.length - 1].visitNumber);

我想以兩種方式找到一些東西，我嘗試在 for 循環中使用 if 條件和以下代碼，但它沒有用，有人可以幫忙嗎？

var jsonObject = xml2Json(responseBody),
    vehicleVisitArray = jsonObject['soap:Envelope']['soap:Body'].findVehicleVisitsResponse.findVehicleVisitsResult.allVehicleVisits.WS_VehicleVisit;
    
    

    for(i = 0; i < vehicleVisitArray.length; i++)
    {
        if(vehicleVisitArray[i].visitNumber == vehicleVisitArray.visitNumber)
        {
            pm.collectionVariables.set("VehicleVisit", vehicleVisitArray[i].visitNumber);
        }
        else
        {
            pm.collectionVariables.set("VehicleVisit", vehicleVisitArray[vehicleVisitArray.length - 1].visitNumber);
        }
    }

Answer 1

var jsonObject = xml2Json(responseBody),
    vehicleVisitArray = jsonObject['soap:Envelope']['soap:Body'].findVehicleVisitsResponse.findVehicleVisitsResult.allVehicleVisits.WS_VehicleVisit;
    
    

    for(i = 0; i < vehicleVisitArray.length; i++)
    {
        if(vehicleVisitArray[i].visitNumber == vehicleVisitArray[0].visitNumber)
        {
            pm.collectionVariables.set("VehicleVisit", vehicleVisitArray[i].visitNumber);
        }
        else
        {
            pm.collectionVariables.set("VehicleVisit", vehicleVisitArray[vehicleVisitArray.length - 1].visitNumber);
        }
    }

您應該添加索引，因為 vehicleVisitArray 是一個數組，並且
