NOAA weather information in hotspot login

I have written a script to grab current weather information. (See below)

I would like to present the global environment variables to the user login page.

I am not seeing them appear. $(weather) Any hints?

/tool fetch url="http://w1.weather.gov/xml/current_obs/KIOW.xml" mode=http 

:global fileContents [/file get [/file find name=KIOW.xml] contents];
                                                   
:local start [:find $fileContents "<station_id>" 0];
:set start ($start + 12 );
:local end [:find $fileContents "</station_id>" $start];
:global "station_id" [:pick $fileContents $start $end];

:set start [:find $fileContents "<weather>" 0];
:set start ($start + 9 );
:set end [:find $fileContents "</weather>" $start];
:global weather [:pick $fileContents $start $end];

:set start [:find $fileContents "<temperature_string>" 0];
:set start ($start + 20 );
:set end [:find $fileContents "</temperature_string>" $start];
:global temperature [:pick $fileContents $start $end];

:set start [:find $fileContents "<wind_string>" 0];
:set start ($start + 13 );
:set end [:find $fileContents "</wind_string>" $start];
:global winds [:pick $fileContents $start $end];
                                              
:set start [:find $fileContents "<observation_time>" 0];
:set start ($start + 18 );
:set end [:find $fileContents "</observation_time>" $start];
:global observation [:pick $fileContents $start $end];

:set start [:find $fileContents "<icon_url_name>" 0];
:set start ($start + 15 );
:set end [:find $fileContents "</icon_url_name>" $start];
:global icon [:pick $fileContents $start $end];

:set start [:find $fileContents "<icon_url_base>" 0];
:set start ($start + 15 );
:set end [:find $fileContents "</icon_url_base>" $start];
:global iconurl ( [:pick $fileContents $start $end] . $icon);

/tool fetch url=$iconurl mode=http

Do they have a web widget / gadet / graphic that contains the info you want, and on a URL on their server so that you could just reference it as an image/script/etc on the login page? If so, do that and add the URL to the walled garden.

Not directly. An icon (fog, rain, sunny, snow, etc) is named in the xml. It could be copied
in the script to the hotspot folder.

I could dynamically build the login.html file as a last resort in the script each hour.
Was hoping there was a "secret" way to get the scripting environment variable exposed
to the hotspot.

Here, use something like this:

Thanks for taking time to help.
I looked at the stickers and decided to dynamically build the login page hourly.
I am bench testing now.
login.html was divided into two parts and reassembled with the information.

:global login1 [/file get [/file find name="hotspot/login1.txt"] contents];
:global login2 [/file get [/file find name="hotspot/login2.txt"] contents];

:global login; 
:set login ($login1);
#:set login ($login . "<p class=\"ws\">");
#:set login ($login . "<img src=\"". $iconurl . "\">");
#:set login ($login . "</p>\r\n");
:set login ($login . "<p class=\"ws\">Weather conditions: " . $weather . "</p>");
:set login ($login . "<p class=\"ws\">Temp: " . $temperature . "</p>\r\n");
:set login ($login . "<p class=\"ws\">Winds: " . $winds . "</p>");
:set login ($login . "<p class=\"ws\">" . $observation . "</p>\r\n");

:set login ($login . $login2);

/file set [/file find name="hotspot/login.html"] contents=$login;

There are a few RSS feeds for other news that I may add later on.

I do hope script globals may be made accessible to the hotspot in the future.
