sum()- Takes a node-set as its argument and returns the sum of the value of each individual node after converting the values to a numeric type if possible.

   <source lang="xml">

File: Data.xml <?xml version="1.0"?> <numbers>

 <x>4</x>
 <y>3.2</y>
 <z>11</z>

</numbers>

 <xsl:template match="numbers">
   4 + 3.2 + 11 =
   <xsl:value-of select="sum(*)" />
 </xsl:template>

</xsl:stylesheet> Output:
