Hi,
     It is quite easy to extract a particular tag from the parser given any of it's attribute name or value (or both), like the following :

NodeList list = newparse.extractAllNodesThatMatch(new AndFilter(new TagNameFilter("TR"),new HasAttributeFilter("Color","Green")));

Now suppose I want to execute the similar operation but with giving the attribute name and/or attribute value as a regular expression. When I tried (passing it as new RegexFilter) it throws an exception; hence I could not do this.
      Is there a way out?
Best Wishes,
                                          Shuvadeep

  You would need to make a filter to do that.
  This has been done for the link tag by John Derrick.
  You would need to loop over attribute values
  See LinkRegexFilter.java:
