RE:  Isolate single result from sorted list
I think you need to copy all future programs to a node-set, then sort
that node-set and select the one in position 1.

Something like this?

<xsl:variable name="futureprograms" select="//programme[@start >
$currentTime]"/>
<xsl:for-each select="$futureprograms">
	<xsl:sort select="@start"/>
	<xsl:if test="position() = 1">
		<xsl:copy-of select="."/>
	</xsl:if>
</xsl:for-each>

Subject:  Isolate single result from sorted list

Hi!

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.

My code can be viewed here:

The output of my code can be viewed here:

http://www.room117.com/sandbox/startTimes.php

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.

Thanks in advance!

Mike
