Hi,
<!--This is the template with recursion to add the prices,
needs test for NaN-->
<xsl:template name="total-value">
<xsl:param name="price"/>
<xsl:param name="result" select="0"/>
<xsl:choose>
<xsl:when test="$price">
<xsl:call-template name="total-value">
<xsl:with-param name="price"
select="$price[position() > 1]"/>
<xsl:with-param name="result"
select="($result + $price)"/>
E.g.Replace this with
<xsl:with-param name="result">
<xsl:choose>
<xsl:when test="string(number($price[1])) = 'NaN'">
<xsl:value-of select="$result"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$result + $price[1]"/>
</xsl:otherwise>
</xsl:choose>
</xsl:with-param>
or place the test outside the xsl:call-template to pass the $result always as a
number.
</xsl:call-template>
</xsl:when>
<xsl:otherwise><xsl:value-of
select="$result"/></xsl:otherwise>
</xsl:choose>
</xsl:template>
Quick test reveals that e.g. in Saxon 6.5.3 if you keep the $price bound to the
same node-set and use a $cursor to point to the node being processed, with
large documents the processing time goes down a third. Though you have to test
if it helps your complete stylesheets and is faster in your choise of XSLT
engine.
