I’ve started using Obsidian with a kanban plugin, though any sufficient kanban style solution would work. I have a to-do column (aka backlog), an in-progress column, and a finished column. I add notes to the cards about what I did and I never delete stuff from the finished column so I can review if I need to re-open or re-do a task in the future.

Yes, I said in my original comment that it can’t universally parse and validate every HTML document. If they’re older pages that don’t do lots of crazy formatting then it’s not too hard to use regex as a first pass then take a second pass through the results to weed out the odd stuff.

I guess it depends on your definition of “parse”, but let me tell you it’s still very painful to deal with things like attributes appearing in any order inside of a tag so I definitely am not advocating to use regex to “read” (or whatever you want to call it) HTML.

I use regex in SQL to parse HTML stored in a database. It can’t universally parse and validate every HTML document, but it can still be used to find specific data like pulling out every link.
