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
