I'm using SOAPpy to access weather data from the NOAA National Digital
Forecast Database XML Web Service [1] and I've been having
trouble figuring out how to parse the data.
The response comes back as XML document but when I check it with
type(result) it shows the the response is a string. Does anyone have any
suggestions on getting relevant data? I've attached a sample SOAP response
to this post.
Thanks,
-Sean
