I need to know how to use xPath’s numeric function within a style sheet

  • 0

I need to know how to use xPath’s numeric function within a style sheet to show the HTML output:

1 + 3 + 4 + 17 + 8 + 15 = 48

The style sheet needs to use numeric function, position(), and a test and conditional statement to present the HTML output.

This is the xml data:

<account>
   <number>1</number>
   <number>3</number>
   <number>4</number>
   <number>17</number>
   <number>8</number>
   <number>15</number>
</account>

This is all I have in my .xsl so far.. It just shows the sum 48…

<?xml version="1.0" encoding="UTF-8" ?>

<xsl:stylesheet version='1.0' xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        <xsl:value-of select='sum(//number)'/>
    </xsl:template>
</xsl:stylesheet>

Any help would be greatly appreciated !

Thank you,

Shaun

    Something like this would work…

    XSLT 1.0

    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="html" indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="account">
        <html>
            <p>
                <xsl:apply-templates select="number"/>
                <xsl:value-of select="concat(' = ',sum(number))"/>              
            </p>
        </html>
    </xsl:template>

    <xsl:template match="number">
        <xsl:value-of select="."/>
        <xsl:if test="following-sibling::number">
            <xsl:text> + </xsl:text>
        </xsl:if>
    </xsl:template>

</xsl:stylesheet>

    HTML Output

    <html>
   <p>1 + 3 + 4 + 17 + 8 + 15 = 48</p>
</html>

    Also, if you must use position() in the stylesheet, you could change the xsl:if to:

    <xsl:if test="position() != count(/*/number)">
    <xsl:text> + </xsl:text>
</xsl:if>
