I need to keep track of a bunch of government-run websites. Each of the websites from from time to time each post notices of upcoming changes to laws and rules. Right now what I do is check them manually, but I’d like to figure out some way to automate the process.
What I’d like is some piece of software that would work as follows. I give it a list of urls. It checks each URL every morning at, say 4:00 am, and downloads the text from the page at that URL. Then it compares that text to whatever text was on the site yesterday. If there is any change, it creates a report, or emails me, or something, letting me know (1) the URL’s for pages that have changed since yesterday, and (2) whatever text has been added to or deleted from the page at that URL.
Can anybody recommend a piece of software that will do this for me, or point me in the right direction?
