NekoHTML - HTML parser for Java

 NekoHTML is a simple HTML scanner and tag balancer that enables
 application programmers to parse HTML documents and access the
 information using standard XML interfaces. The parser can scan HTML
 files and "fix up" many common mistakes that human (and computer)
 authors make in writing HTML documents. NekoHTML adds missing parent
 elements; automatically closes elements with optional end tags; and
 can handle mismatched in-line element tags.
