I index configuration, metadata xml and content pieces with lucene. When 
doing the search I get the hits and take field values and form that into 
XML to be styled by XSL (resulting in something similar to what you 
have, I think). You can even index your XSL offline for your own use :). 
 Anyway, using this:


QueryHighlightExtractor qhe = new QueryHighlightExtractor(query,
                                    new StandardAnalyzer(),
                                    "<span class='highlight'>",
                                    "</span>");

will do what you want.

A while ago I did searches with XSL and found it to be extremely 
resource intensive, in our case. Indexing with Lucene is extremely fast 
and searching that index is extremely fast and light on resources. There 
are many types of searches that are ridiculously hard with XSL (i.e. 
fuzzy queries). Check out the contributions and sandbox on the lucene 
site - you can probably have something up and running within a day.
