HTML-parser provides a parser for HTML 5 that produces HTML 5 document object model. It aims to be a Java-implementation of http://www.w3.org/TR/html5/. It is for use in the server. It does not implement features that are relevant in the client, like event handling. It is for use from javascript, via Java's scripting library.
The newest version!

 *  The StyleSheet interface is the abstract base interface for 
 * any type of style sheet. It represents a single style sheet associated 
 * with a structured document. In HTML, the StyleSheet interface represents 
 * either an external style sheet, included via the HTML  LINK element, or 
 * an inline  STYLE element. In XML, this interface represents an external 
 * style sheet, included via a style sheet processing instruction. 
 * See also the Document Object Model (DOM) Level 2 Style Specification.
