I changed the code according to the suggestions, except the array comment where I had no idea if I should check array size or handle an exception

Looks good to me, thanks! 🍻 I'll merge and bump version this weekend.

I like the

(*) offline saved files only. Page requires login

note and we'll start using it going forwards.

Would you mind sharing how you use the package? Looks like you are downloading a file + scrape the html separately. Your input will help us determine what updates to implement.

Saving a file html file from Browser and have that scraped is what I did for development and I let the test class feed it to the scraper.
In the real world, I'm hoping on tandoor sending the data from the bookmarklet or the big "try to import any text" to the new scraper.

I'm slightly uneasy about supporting login-required scrapers (even when offline), partly because of the test data alongside each scraper. Currently those test files are retrieved from public websites - anyone could/should see the same results, and anyone can later check/update/fix the scraper by retrieving it again.
