Hi List.
I am trying to create a simple function to multiply each item in a
sequence by each other (like a sum()).
My problem is that I am unable to have the parameter treated as a node
sequence (using saxon, so XSL2.0)
I have
<xsl:template name=" multiplie">
<xsl:param name="serie"/>
<xsl:param name="result" as="xs:double"/>
<!--some test output -->
<xsl:value-of select="$serie"/>-<xsl:value-of
select="$result"/>--
###<xsl:value-of select="count($serie)"/>###
<!-- -->
<xsl:choose>
<xsl:when test="count($serie) gt 1">
<!-- make the multiplication between result and
the first item in the serie, then remove it and call again -->
<xsl:variable name="comp">
<xsl:value-of select="number($serie[1])
* $result"/>
</xsl:variable>
<xsl:call-template name=" multiplie">
<xsl:with-param name="serie"><xsl:copy-of
select="subsequence($serie,2)"/></xsl:with-param>
<xsl:with-param name="result"><xsl:value-of
select="$comp"/></xsl:with-param>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="number($serie[1]) *
$result"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
That I can call (for testing) with
<xsl:variable name="seq" select="(6.8E-06,5.5E-06,7.1E-06,7.3E-06)"/>
<xsl:value-of select=" multiplie($seq)"/>
And the output I get
#############################################
6.8E-06 5.5E-06 7.1E-06 7.3E-06
#############################################
0.0000068 0.0000055 0.0000071 0.0000073-1--
####
NaN
#############################################
So, the part where I do a count gets me 1, when I should have 4...
I have tried with
<xsl:param name="serie" as="node()*"/> but I have an error message
XTTE0790: Required item type of first argument of multiplie() is node();
supplied
value has item type xs:double
I am a bit out of ideas....
Thank you in advance for any help.
Best regards,
Fabien
