* gh-135661: Fix parsing start and end tags in HTMLParser according to the ↵Serhiy Storchaka2025-07-031-74/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HTML5 standard (GH-135930) * Whitespaces no longer accepted between `</` and the tag name. E.g. `</ script>` does not end the script section. * Vertical tabulation (`\v`) and non-ASCII whitespaces no longer recognized as whitespaces. The only whitespaces are `\t\n\r\f `. * Null character (U+0000) no longer ends the tag name. * Attributes and slashes after the tag name in end tags are now ignored, instead of terminating after the first `>` in quoted attribute value. E.g. `</script/foo=">"/>`. * Multiple slashes and whitespaces between the last attribute and closing `>` are now ignored in both start and end tags. E.g. `<a foo=bar/ //>`. * Multiple `=` between attribute name and value are no longer collapsed. E.g. `<a foo==bar>` produces attribute "foo" with value "=bar". * Whitespaces between the `=` separator and attribute name or value are no longer ignored. E.g. `<a foo =bar>` produces two attributes "foo" and "=bar", both with value None; `<a foo= bar>` produces two attributes: "foo" with value "" and "bar" with value None. * Fix Sphinx errors. * Apply suggestions from code review Co-authored-by: Ezio Melotti <ezio.melotti@gmail.com> * Address review comments. * Move to Security. --------- Co-authored-by: Ezio Melotti <ezio.melotti@gmail.com>

* gh-86155: Fix data loss after unclosed script or style tag in HTMLParser ↵Waylan Limberg2025-05-101-1/+1
| | | | | | | (GH-22658) When calling .close() the HTMLParser should flush all remaining content, even when that content is in an unclosed script or style tag.
