But the problem I get with the 'summary' I want to produce using the statistics.xsl stylesheet, which looks like this:
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="entry/statistics">
<xsl:for-each select=".">
That for-each select="." does not achieve anything.
<xsl:variable name="end"><xsl:value-of select="preceding-sibling::statistics[1]/time"/></xsl:variable>
The "statistics" element does not have preceding sibling elements of the
same name, I think you want
<xsl:variable name="end"
select="../preceding-sibling::entry[1]/statistics/time"/>
<xsl:variable name="start"><xsl:value-of select="time"/></xsl:variable>
Doing
<xsl:variable name="start" select="time"/>
is shorter, easier and more efficient.
