The Validator.nu HTML Parser is an implementation of the HTML5 parsing algorithm in Java for applications. The parser is designed to work as a drop-in replacement for the XML parser in applications that already support XHTML 1.x content with an XML parser and use SAX, DOM or XOM to interface with the parser.

There is a newer version: 1.4.16
