Hello every one, 
this script will get the weather and the temperature from Yahoo web site.
I tried to not be intrusive by hiding Safari and displaying a notification.
I tried to create handler that may be reused later.
If you don’t live in France (which I suppose you do 
), you’ll have to modify
the following properties in the code :
property weatherURL : “https://fr.news.yahoo.com/meteo”
property temperatureScale : “°C”
Set weatherURL property to the correponding URL of yahoo web site in your country.
Set the temperatureScale property to the corresponing scale used in your country.
Then you go …
Algorithm :
- Get the source code of the web page (with Safari)
- Filter the source code to manipulate only weather infos (by selecting text between boundaries)
- Find the weather in the code (by selecting text between boundaries)
- Find the temperature in the code (by selecting text between boundaries)
- Display infos with a notification
DISCLAIMER :
- This script has only been tested on the french version of the yahoo web site;
you may have to change the boundaries (see following code) to find the infos
on the yahoo web site of your country. - If Yahoo updates its web site, you may have to change the boundaries again …

-- - If Yahoo change its web site, you'll have to find the new boundaries
-- - From idea of Curtranhome of macscripter.net
