I can get single item by

print(xml!["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","ItemType"].text)

but for the array I can not get the detail. How to access array member? Any help is much appreciate. Thanks

    <DeliveryStatusDetails>

                        <StatusDescription>Recovered item from POPStation for service recovery</StatusDescription>

You can access the Child Array content as follows:

print(xml["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","DeliveryStatusDetails","DeliveryStatusDetail",0,"Location"].text)

The "DeliveryStatusDetail",0 denotes that you want to access the 0th position DeliveryStatusDetail element.

To enumerate through the array:

for DeliveryStatusDetail in xml["ItemTrackingDetailsResponse","ItemsTrackingDetailList","ItemTrackingDetail","DeliveryStatusDetails","DeliveryStatusDetail"] {
    print(DeliveryStatusDetail["Location"].text)
}

work perfectly. Thanks a lot!. But how can we loop through the array?

Lê Khánh Vinh Over a year ago

thanks, it easier to work with XML now. Anyway we can print the whole xml (to test out whether response is correct)?

Lê Khánh Vinh Over a year ago

like a whole xml as a string so we can see what is inside!

Yes, use this code: let datastring = String.init(data: xmlData, encoding: NSUTF8StringEncoding)
