Summing nodes with same id number....

Question

I thought this would be simple but I'm struggling with it. I have a template called "entry" that outputs account details and after each account for a paricular customer, should sum the total balance and output that also. I can't get the summing to work and I've googled and can't find what I'm looking for. Below is a shell of the template that I have so far. All suggestions welcome...
<xsl:template match="entry">
<xsl:value-of select="StatementDate"/>
<xsl:value-of select="AccountNumber"/>
<xsl:value-of select="EndingAcctBalance"/>
<xsl:text>&#10;</xsl:text> <!-- End of Row -->
</xsl:template>
Thanks,
TI

Answer 1

yue42, is this to be done inside the entry template? here's more of my stylesheet (in case it helps):
This is what I'm looking to do:
Acct A 3000 BAL
Acct A 4000 BAL
Acct A 5000 BAL
Acct A 12000 TOTAL
Acct B 1000 BAL
Acct B 2000 BAL
Acct B 3000 TOTAL
Here's my stylesheet...the data is being passed from a resultset.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" omit-xml-declaration="yes"/>
<xsl:param name="date"/>
<xsl:param name="fileHeader"/>
<xsl:param name="columnHeader"/>
<xsl:param name="fileTrailer"/>
<xsl:template match="/">
<xsl:apply-templates select="result"/>
</xsl:template>
<xsl:template match="result">
<xsl:if test="$fileHeader='Y'">
<xsl:call-template name="header"/>
</xsl:if>
<xsl:if test="$columnHeader='Y'">
<xsl:call-template name="columnheader"/>
</xsl:if>
<xsl:apply-templates select="entry"/>
<xsl:if test="$fileTrailer='Y'">
<xsl:call-template name="trailer"/>
</xsl:if>
</xsl:template>
<!-- Column header definition for Balances files -->
<xsl:template name="columnheader">
<xsl:text>BANK,Date,Account Number,Account Type,Currency,Total Equity,Type</xsl:text>
<xsl:text>&#10;</xsl:text>
</xsl:template>
<xsl:template match="entry">
<xsl:text>BANK</xsl:text><xsl:text>,</xsl:text>
<xsl:value-of select="StatementDate"/><xsl:text>/</xsl:text>
<xsl:value-of select="AccountNumber"/><xsl:text>-</xsl:text>
<xsl:value-of select="AccountBalanceCurrency"/> <xsl:text>,</xsl:text>
<xsl:value-of select="EndingAcctBalanceLocal"/><xsl:text>,</xsl:text>
<xsl:text>BALANCE</xsl:text>
<xsl:text>&#10;</xsl:text> <!-- End of Row -->
</xsl:template>
</xsl:stylesheet>
