One weird trick for monitoring web pages

Using Github Actions as a tool for webpage change notification

Want to get an email when a certain bit of text on a page has changed?

Use Github Actions!

1. Fork this repo
2. Edit the top bit of .github/workflows/pagediff.yaml:

   env:  # Define diff target here
     # The page to visit
     URL: 'https://sebbacon.github.io/'
     # The XPath for the content you're interested in
     # (try right-clicking the element in the inspector in Chromium)
     XPATH: '/html/body/header/div/a'
     # A filename where we will save the contents of that XPath
     FILE_PATH: 'sebbacon.html'

3. Set up Email Notifications (in the Settings of your repo) to get an alert when the action fails (i.e. when there's a new diff to report)

Thanks to Dave for pointing out this one wierd trick some years ago.
