@amoroso cl-html5-parser (https://github.com/rotatef/cl-html5-parser)

It’s an abandoned yet (fully?) compliant HTML parser that actually parses all the HTML you may find in the wild. As compared to Plump, which is mostly an XML parser and breaks on (a widespread set of) non-XML-y pages.

One of my projects I keep postponing is a cl-html5-parser -> plump conversion library. It’s important because Plump has nice DOM utilities, but lacks a compliant HTML parser.

@aartaka As other old Common Lisp software I'd say it's mature, not abandoned.
@amoroso not in this case. Unfortunately WHATWG keeps adding stuff to HTML standard, so good parser needs to track that and do the (lots of) necessary changes. Still, cl-html5-parser is a good step in the right direction!
