Thanks, Wendell, for the information about binding a variable to the
sorted result tree fragment. Since my friend's need was to grab the
earliest and latest dates and the dates are guaranteed to be 10
characters long (2004-01-31) he can use a much simpler approach than I
sent him previously:
Good: glad to hear it.
<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
version='1.0'>
<xsl:output method='html'/>
<xsl:template match="/root">
<html>
<xsl:variable name="ND">
<xsl:apply-templates select="//nd">
<xsl:sort/>
</xsl:apply-templates>
</xsl:variable>
<xsl:call-template name="test_template">
<xsl:with-param name="b"><xsl:value-of select="substring($ND, 1,
10)"/></xsl:with-param> <!-- earliest date -->
<xsl:with-param name="c"><xsl:value-of select="substring($ND,
string-length($ND)-9, 10)"/></xsl:with-param> <!-- latest date -->
</xsl:call-template>
These parameter assignments might be expressed more nicely as
<xsl:with-param name="b" select="substring($ND, 1, 10)"/>
<xsl:with-param name="c" select="substring($ND, string-length($ND)-9, 10)"/>
Interestingly, the reason this is preferable is that these values are now
of type string, not RTF, which means (among other subtleties like
probably-better performance) that they will cast more intuitively to
Booleans (not that that matters here).
Cheers,
Wendell
