JTidy is a Java port of HTML Tidy, a HTML syntax checker and pretty printer. Like its non-Java cousin, JTidy can be
used as a tool for cleaning up malformed and faulty HTML. In addition, JTidy provides a DOM interface to the
document that is being processed, which effectively makes you able to use JTidy as a DOM parser for real-world HTML.
The newest version!
