Re: conditional element counting

I would like to count the number of nodes that have an element containing a
specific element value
...
I want to use XSL to count and display the number of Person nodes that have
an Age element with value = 10.

T:\ftemp>type darren.xml
<Rootnode>
  <Person>
    <Name>Joe</Name>
    <Age>10</Age>
  </Person>
  <Person>
    <Name>John</Name>
    <Age>10</Age>
  </Person>
  <Person>
    <Name>Sam</Name>
    <Age>18</Age>
  </Person>
</Rootnode>

T:\ftemp>type darren.xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="/">
  <xsl:value-of select="count( /Rootnode/Person[Age=10] )"/>
</xsl:template>

</xsl:stylesheet>
T:\ftemp>saxon darren.xml darren.xsl
2
T:\ftemp>
