That's true, although I've also seen scraping fail because it was being too precise – looking for something at a particular point in the DOM tree because the parser encourages things like XPaths or CSS selectors, where a regex would have been less brittle _for that use-case_.

For me this just highlights why it's important that engineers understand at some basic what these different things all mean, and what limitations you may have with your solutions, or even those you may want.
