Kai,

That works.  Unfortunately the punctuation marks (matched text) are returned
as separate list entries.  Is there any way to avoid having to walk the list
by steps of 2, and rejoin the "n" and "n+1" elements, to get back the
original sentence(s)?  I'm trying to save some processing time if possible.

Thanks,
