To have shifted goalposts, I would have had to have said one thing, and then say something different. But I only made a single comment.

OP moves the goalposts, not the comments:

"Here’s my HTML lexer. It doesn’t try to do a validating parse; it just identifies the lexical elements. You might think of it more as an HTML chunker than an HTML parser. It isn’t very forgiving of broken HTML, although it makes some very small allowances in that direction."
