The clientraw.txt file is a simple space-delimited text file with the format described in a 'clientrawdescription.txt' in the Weather-Display main directory.
There are actually several of these space-delimited files:
clientraw.txt (updated frequently, like every 5 seconds)
clientrawdaily.txt (updated once a day)
clientrawextra.txt (updated about every 5 minutes) and
clientrawhourly.txt (updated once an hour).
The files other than clientraw.txt contain information on history and records for various weather variables.
You can see the contents of a current WD set of files thanks to Krelvinaz's very useful Clientraw Parser (
http://www.tnetweather.com/wd-parser.php ) .. you can use my site (
http://saratoga-weather.org/ ) as the URL to take a look at the current values.
The Vista WD gadget cited above uses clientraw.txt, clientrawextra.txt for it's displays.
The Weather-Display Live Flash control uses clientraw.txt, clientrawdaily.txt and clientrawextra.txt for it's displays.
The Yahoo widget uses only clientraw.txt (as far as I know), so it's the only one that might be 'bent' to use a different datafile format and display stuff from WeatherLink.
With all that in mind, I recommend you get VirtualVP and Weather-Display to get the real-time info you'd like to have for your website
