Help with splitting variables

I have an api from worldweatheronline and it returns a csv result. How do I split the csv variables to return certain parts of the result? I have looked at different profiles and have seen HTTPD with a number. Does the number correspond to a value before the comma? The "labels" of the values are returned on line 4 of the csv file and the values themselves are returned on line 9. Any help would be much appreciated.
