Hi Folks,

So, you've got an XSLT program that is taking a long time to execute. You want
to find out what part of the program is taking so much time.  You need to
insert some start/stop timers into your XSLT. Here's how to do it:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:date="java:java.util.Date"
                version="2.0">

    <xsl:output method="text" />
    <xsl:output name="text-format" method="text"/>

    <xsl:template match="/">
        <!-- Start a timer -->
        <xsl:variable name="start" select="date:getTime(date:new())" />

        <!-- Do your XSLT processing -->
        <xsl:apply-templates />

        <!-- End the timer -->
        <xsl:variable name="end" select="date:getTime(date:new())" />

        <!-- Log the benchmarking results to a file, time-info.txt -->
        <xsl:result-document href="time-info.txt" format="text-format">
            start: <xsl:value-of select="$start" />
            end: <xsl:value-of select="$end" />
            diff: <xsl:value-of select="$end - $start" />
        </xsl:result-document>

    </xsl:template>

    <xsl:template match="*">
        <!-- Do something -->
        <xsl:text>Hello World </xsl:text>
        <xsl:value-of select="current-dateTime()" />
    </xsl:template>

</xsl:stylesheet>
