RE: Summating/grouping

Any chance of correcting my example xsl?

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<!--	I am hoping that this builds up a list of all the items by Tax rate
code -->
	<xsl:key name="TAX" match="/Invoice/InvoiceLine/Charge[@Type =
'Tax']/TaxRate" use="@Code"/>
	<xsl:template match="/">
		<TaxSummary>
			<!--	I am hoping that this will return the first element of each of the
Tax codes, i.e. 'S', 'E', 'Z' -->
			<xsl:for-each select="/Invoice/InvoiceLine/Charge[@Type =
'Tax']/TaxRate/@Code[generate-id(.)=generate-id(key('TAX', @Code)[1])]">
				<!-- this should be the TaxRate Code -->
				<xsl:variable name="CODE" select="."/>
				<Tax Code="{$CODE}">
					<Rate>
						<xsl:value-of select="TaxRate"/>
					</Rate>
					<LinesAtRate>
						<xsl:value-of select="count(/Invoice/InvoiceLine/Charge[@Type =
'Tax']/TaxRate[@Code = $CODE])"/>
					</LinesAtRate>
					<Value>
						<xsl:value-of select="sum(/Invoice/InvoiceLine/Charge[@Type =
'Tax']/TaxRate[@Code = $CODE]/../Value)"/>
					</Value>
				</Tax>
			</xsl:for-each>
		</TaxSummary>
	</xsl:template>
</xsl:stylesheet>

Thanks

<xsl:for-each select="/Invoice/InvoiceLine/Charge[@Type =
'Tax']/TaxRate/@Code[generate-id(.)=generate-id(key('TAX', @Code)[1])]">

               ^here your current node is a code attribute
but the predicate will be false for all of them as the keuy matches 
Charge elements.
