Mythweather unable to retrieve weather data from NDFD

[abauer <knnniggett@…>]

Problem:
Mythweather is unable to display weather data from any screen that uses NDFD (e.g. 18 hour forecast, six day forecast, etc). Other screens that use NOAA and wunderground appear to work fine.

Relevant System Info:
Mythbuntu 12.04 x86_64
Mythtv 0.25.1 + latest fixes

Steps to reproduce:
Add 18 hour forecast & Six Day Forecast as an active screen, using a location of “KBLV”, then observe that these screens do not populate when they are viewed. In addition to my htpc, I have been able to reproduce this issue in a virtual machine with a fresh install of Mythbuntu 0.25.1.

I verified that the package “libdatetime-format-iso8601-perl” is installed.

Perhaps this is a clue?

Looks like the script does not understand what NDFD is sending it. Has the format changed?

I have the same issue. It hasn't worked in the last 2 releases.

(Maybe you should just omit the defined()?)

I'll take a look. As for "it hasn't worked in the last 2 releases", that is questionable. This script has been changed at least once during that timeframe, and this is the first I've heard of the bug.

I'm sure the format has changed, and that's the issue.

Reworked all of the NOAA/NWS Weather Scripts

Seems weather.gov has moved the urls for nearly all their data services. On
top of that, the SOAP response is gzip encoded by default, and SOAP::Lite is
stupid and can't handle it. Also, we were missing the Units parameter which
is now required.

Fixes #10821
