Oddly enough, I came to almost exactly the same regexp independently, 
after discovering and reading this perl site 
<http://search.cpan.org/dist/perl/pod/perlre.pod>.  The one I came up 
with that I've verified actually works (even with the 'old' 0.27 orca) is: 


For a period during the trial & error, it seemed that having mixed 
length strings (as in your expression) wasn't working.  Perhaps because 
of the way I did the grouping, or maybe web browser caching was 
confusing things (though I thought I did a shift-reload after every 
'orca -once').  I'll give your expression a try, and see if it changes 
anything.  If it works, I'll change it, as your expression is more clear.
