Specifically: 1) The script nwsxml.pl in the current SVN is not properly parsing data returned by the National Weather Service XML feed. 2) The weather-screens.xml file currently contains a reference that causes the Current Conditions screen to completely ignore NWS as a usable source. 3) The scripts/README file makes reference to the weather-screens.xml but has a typo/error with regard to the flag passed to the scripts in question (-T instead of -t) ---- Detailed information: 1) the script nwsxml.pl is not properly parsing data returned, and is trying to fill array values with data that is not available, resulting in a concatenation error: {{{ mythtv2:~/src/mythtv/trunk/mythplugins/mythweather/mythweather/scripts/us_nws$ ./nwsxml.pl -u ENG KSFO cclocation::San Francisco Intl Airport, CA station_id::KSFO latitude::37.62 longitude::-122.36 observation_time::Last Updated on Sep 22 2009, 10:56 am PDT observation_time_rfc822::Tue, 22 Sep 2009 10:56:00 -0700 weather::A Few Clouds temperature_string::68.0 F (20.0 C) temp::68.0 relative_humidity::68 wind_string::Northwest at 8.1 MPH (7 KT) wind_dir::Northwest wind_degrees::310 wind_speed::8.1 Use of uninitialized value in concatenation (.) or string at ./nwsxml.pl line 151. wind_gust:: pressure_string::1016.1 mb pressure::30.01 dewpoint_string::57.0 F (13.9 C) dewpoint::57.0 Use of uninitialized value in concatenation (.) or string at ./nwsxml.pl line 151. heat_index_string:: Use of uninitialized value in concatenation (.) or string at ./nwsxml.pl line 151. heat_index:: Use of uninitialized value in concatenation (.) or string at ./nwsxml.pl line 151. windchill_string:: Use of uninitialized value in concatenation (.) or string at ./nwsxml.pl line 151. windchill:: visibility::10.00 weather_icon::pcloudy.png Use of uninitialized value in string eq at ./nwsxml.pl line 131.

Which brings us to #2 ... 2) The weather-screens.xml file contains a reference in the Current Conditions block that is not provided by the nwsxml.pl script (working or otherwise). This causes the Current Conditions screen to completely ignore NWS as a usable source. The reference in question is: {{{ }}} and this field is not mentioned in the nwsxml.pl script. Once this line is commented out, the Current Conditions screen will use NWS as a source once MythWeather's Screen Setup is re-run. I believe there is syntax to make these fields optional or mandatory but I'm not sure if that code is fully implemented yet. Which brings us to ... 3) the scripts/README file contains this copy in reference to weather-screens.xml: {{{ The text of the name within the weather-ui.xml file (with prepending flag removed) must match exactly the string returned by the -T flag; as well as the token returned when retrieving data. }}} Actually, '-T' is the flag that shows default timeout values. The flag '-t' is used to provide the usable strings as provided by a given script. The README should probably be updated with this minor change.
