Applying this I'm stumped. In my version I am parsing nodes with
class='placed'. You will notice in the $EMP XML there are 1 type 2s
and 5 type 3s. But the below XML only returns 1101 (only counts the 1
type=2).
If I change the '1' in generate-id(key('by-type', @type)[1]) to '2',
it counts the 5 type=3's
XML contents of $EMP
<Records>
<Record>
<type>1</type>
<class>unplaced</class>
<count>3</count>
</Record>
<Record>
<type>2</type>
<class>placed</class>
<count>1</count>
</Record>
<Record>
<type>2</type>
<class>unplaced</class>
<count>8</count>
</Record>
<Record>
<type>3</type>
<class>met45</class>
<count>1</count>
</Record>
<Record>
<type>3</type>
<class>placed</class>
<count>5</count>
</Record>
<Record>
<type>3</type>
<class>unplaced</class>
<count>14</count>
</Record>
</Records>
XML contents of $types
<vrType>
<option value="1" benchmark1="540.00"
benchmark2="540.00"
benchmark3="720.00" />
<option value="2" benchmark1="1101.00"
benchmark2="1101.00"
benchmark3="1468.00" />
<option value="3" benchmark1="1801.50"
benchmark2="1801.50"
benchmark3="2402.00" />
</vrType>
XSL-----
<td>
<xsl:variable name="rtfm">
<xsl:for-each select="$EMP[class='placed' and generate-id() =
generate-id(key('byType',type)[1])]">

Here is another possible solution (using node-set extension function):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:common="http://exslt.org/common";
exclude-result-prefixes="common"
version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:key name="by-type" match="contact" use="@type" />
<xsl:template match="/x">
<totals>
<xsl:variable name="rtf">
<xsl:for-each select="contacts/contact[generate-id() =
generate-id(key('by-type', @type)[1])]">
<temp><xsl:value-of select="count(key('by-type', @type)) *
../../types/type[(_at_)value = current()/@type]/@benchmark1" /></temp>
</xsl:for-each>
</xsl:variable>
<benchmark val="{sum(common:node-set($rtf)/temp)}" />
</totals>
</xsl:template>
</xsl:stylesheet>
When the above stylesheet is applied to the following XML:
<?xml version="1.0"?>
<x>
<types>
<type value="1" benchmark1="540" />
<type value="2" benchmark1="640" />
<type value="3" benchmark1="740" />
</types>
<contacts>
<contact type="1" />
<contact type="2" />
<contact type="3" />
<contact type="3" />
</contacts>
</x>
The output produced is:
<?xml version="1.0" encoding="UTF-8"?>
<totals>
<benchmark val="2660"/>
</totals>
