XSLT and SUM()

[JoeMcGarvey]

I have been reading about sum() to evaluate some (pardon the pun) nodes. I am very confused and cannot get anything working.

Here is my (simplified) XML:

<entity>
<value>55</value>
</entity>
<entity>
<value>7</value>
</entity>
<entity>
<value>18</value>
</entity>

How do I write my XSL to add the <value> nodes to return the total? Do I use &quot;sum()&quot; with a &quot;call-template&quot; and what should that called template look like?

Thanks!!

This will get you the sum which you could use this in any template.

<xsl:value-of select=&quot;sum(//value)&quot;/>


<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>
<xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;>

<xslutput method=&quot;html&quot;/>
<xsl:template match=&quot;/&quot;>
<xsl:value-of select=&quot;sum(//value)&quot;/>
</xsl:template>
</xsl:stylesheet>
