What steps will reproduce the problem?
1. The problem is random and only arises when the 'wind' attribute is empty.
2. n/a
3. n/a

What is the expected output? What do you see instead?

  File "weather.py", line 386, in <module>
    myDisp.UpdateWeather()
  File "weather.py", line 91, in UpdateWeather

    'wind')[0].getElementsByTagName(tag2)[0].firstChild.data
AttributeError: 'NoneType' object has no attribute 'data'


What version of the product are you using? On what operating system?

pywapi-0.3.8 on both Ubuntu 14.04 and Raspberry Pi Debian Wheezy


Please provide any additional information below.

This error does not appear 100% of the time. It only pops up when the 'wind' 
tag is empty/missing.
