I'm trying to make a simple Vista sidebar gadget that monitors the online status of specified Xbox Live users, but my knowledge on HTML, PHP, CSS and Javascript is very limited. Is there a way to monitor a webpage and detect keywords e.g. "online" or "offline" and display the results on the gadget by using any of these four scripting languages? Here's a little example of what I'm looking for if it helps:
"If keyword 'online' is detected on www.example.com, display 'online' HERE"
"If keyword 'offline' is detected on www.example.com, display 'offline' HERE"

Thankyou
