Apologies if that's the wrong place, but have no clue where to ask.
What would be the easiest, simplest way to do that? I've read about webcrawlers, webscrappers, but they seem to be doing far more than we need. We basically want to run from our PCs connected to internet a small script that will do that simple check and send us email as soon as the change to the specific part of html body has been detected (or to be more specific - selected elements have not been found).
Any help greatly appreciated
