Hi, I'm trying to get the sum of named columns but
am running into trouble. I'd like to get the total for
columns having a hasTotal attribute. The xsl fragment I'm 
trying to use is below. The problem is that the nodelist
param is illegal (select="//$curname"). I can't seem to 
create a nodelist without hardcoding the element name
(select="//TradeType"), but I don't know in advance which
elements will be present and which ones have totals. 

<xsl:for-each select="TradeEntry[position()=1]/*">
	<xsl:variable name="curname" select="name(current())" />
	<xsl:if
test="//ColumnInfo/column[@colname=name(current())]/@hasTotal">
		<xsl:call-template name="getSum">
			<xsl:with-param name="nodelist"
select="//$curname"/>
		</xsl:call-template>
	</xsl:if>
</xsl:for-each>   	

<xsl:template name="getSum">
	<xsl:param name="nodelist"/>
	<xsl:value-of select="sum($nodelist)"/>
</xsl:template>
		
myData.xml ===========================================
<?xml version="1.0" ?>

<TradeData date='2002-03-18'>
	<ColumnInfo>
		<column colname="TradeType" align="left"/>
		<column colname="TradeId" align="center"/>
		<column colname="TradeValue" align="right" hasTotal="true"/>
	</ColumnInfo>

	<Trades>
		<TradeEntry>
			<TradeType>TypeA</TradeType>
			<TradeId>12345</TradeId>
			<TradeValue>100.00</TradeValue>
		</TradeEntry>
		<TradeEntry>
			<TradeType>TypeB</TradeType>
			<TradeId>45678</TradeId>
			<TradeValue>500.00</TradeValue>
		</TradeEntry>
		<TradeEntry>
			<TradeType>TypeC</TradeType>
			<TradeId>56789</TradeId>
			<TradeValue>350.00</TradeValue>
		</TradeEntry>
	</Trades>
</TradeData>
