SOLUTION - PROGRAM MANAGEMENT - How to sum of property over the ITEM Type

AbhishekSrivastava - Friday, October 7, 2016 7:26 AM:

Hi Friends,

If i want to count Items on Item Type then i have a code.

<xsl:stylesheet version="1.0" xmlns:xsl="www.w3.org/.../Transform">
 <xsl:output method="xml" omit-xml-declaration="yes"/>
 <xsl:template match="/"><Result><xsl:value-of select="count(//Item[@type='MACHINE ENTRY'])"/></Result></xsl:template>
</xsl:stylesheet>

Count is successful.

If I have a property name machine_hours and I want to sum machine_hours, so What changes required on above code.

Thanks in Advance

Hi Abhishek,

The XSLT you've provided counts the items of type "MACHINE ENTRY" using the standard XPath count() function. Similarly, you can use the standard XPath sum() function to sum property values from the result. 

Example:

<xsl:value-of select="sum(//Item[@type='MACHINE ENTRY']/machine_hours)"/>

Sum function documentation: https://msdn.microsoft.com/en-us/library/ms256160(v=vs.110).aspx
