Is There A Script That...
 

Will scan a list of online html pages and create a report of pages that have changed since the last scan?

Or where is the best place to get something like this made at a reasonable price?

I'm sure there is something out there, check freshmeat.net. One 'simple' way to do this is via wget and diff, but you wouldn't like the output. This would be something of a regex nightmare to do, but could be done.

Best idea would be to get the code from the html page and give it a file size into a database, then check the file size of the new page, if their different then its changed.

could write you 1 fast, perl/mysql ... need details to set a price, contact me

true, but won't tell you whats changed. for that matter just md5 them and diff the hashes, though that still won't tell you whats changed.

you need something that runs out of cron, that can take a snapshot of a given page at any given time, parse it, and checkpoint the changes.

Easy to do in perl+mysql+wget. Just time consuming.

i wrote one in vb..checks all the links every 5 minutes...if anything has changed on a page it will notify you. I would have to modify it a little for someone else to work with.
