RE: [xsl] Applying Attributes with Grouping Method

["Fanghanel, Karl" <Karl.Fanghanel@xxxxxxxxx>]

Thanks for the input Dave.

I did consider and tried using for-each-group but I couldn't get it to
work.
I think I now know why.

Keep doing it, you get used to it eventually!

you are using saxon8 so XSLT2 so you don't need Muenchian grouping,
once I'd made your input example well formed, it's just a call to
xsl:for-each-group:

<connection>
	<conn name="P21" part="W1123">
		<property name="s_des" val="Part_A"/>
	</conn>
	<conn name="P22" part="W1123">
		<property name="s_des" val="Part_A"/>
	</conn>
	<conn name="P23" part="W1123">
		<property name="s_des" val="Part_A"/>
	</conn>
	<conn name="J31" part="W1144">
		<property name="s_des" val="Part_B"/>
	</conn>
	<conn name="J32" part="W1145">
		<property name="s_des" val="Part_C"/>
	</conn>
</connection>




<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output indent="yes"/>

  <xsl:template match="connection">
    <report>
      <xsl:for-each-group select="conn"
group-by="property[@name='s_des']/@val">
	<item part="{@part}"
	uantity="{count(current-group())}"
	val="{current-grouping-key()}"
	name="{current-group()/@name}"/>
      </xsl:for-each-group>
    </report>
  </xsl:template>

</xsl:stylesheet>


$ saxon8 connection.xml  connection.xsl
<?xml version="1.0" encoding="UTF-8"?>
<report>
   <item part="W1123" uantity="3" val="Part_A" name="P21 P22 P23"/>
   <item part="W1144" uantity="1" val="Part_B" name="J31"/>
   <item part="W1145" uantity="1" val="Part_C" name="J32"/>
</report>
