I would like to refresh a web page based on a list of "program start
times" contained in XML format.  I can select and sort the start
times, but I am having trouble isolating the *next* start time.  In
other words, XSLT formats a list of results (as one would expect) but
I need to identify a single result.

After scouring the web and searching the archives for this list, I
attempted many solutions but could not make any work---I am completely
stumped.  I will be eternally grateful if someone could suggest a
simple, straightforward solution.
