    Use the jsoup HTML Cleaner with a configuration specified by a Whitelist.

    String unsafe = 
  "<p><a href='http://example.com/' onclick='stealCookies()'>Link</a></p>";
String safe = Jsoup.clean(unsafe, Whitelist.basic());
// now: <p><a href="http://example.com/" rel="nofollow">Link</a></p>

    Excerpt from the Jsoup Cookbook.
