Steve Yegge explains how to use Ruby to script your Windows applications. His first example demonstrates how to load Internet Explorer, get it to navigate to a certain Web page, and scrape the content in just five lines of code, like so:

require 'win32ole'
ie = WIN32OLE.new('InternetExplorer.Application')
ie.navigate("http://{internal-website}/your-desired-url")
sleep 1 while ie.readyState() != 4
html = ie.document().documentElement.outerHTML
ie.quit()

Excellent! This makes me wonder if there's a similar mechanism (not AppleScript) for OS X. Anyway, learn more, including more complex demonstrations, at Steve's post.
