[xsl] summing set of records

["anil an.kumar" <anil.an.kumar@xxxxxxxxxx>]

Hi Team,

i want the out put like below...

<mezo eazon="OB0001X1CA">200</mezo>
<mezo eazon="OB0001X2CA">150</mezo>
<mezo eazon="OB0001X3CA">350</mezo>   ->  This line has to print for 
every two set of records  ex:  sum of OB0001X1CA (200) + OB0001X2CA(150)
<mezo eazon="OB0002X1CA">300</mezo>
<mezo eazon="OB0002X2CA">50</mezo>
<mezo eazon="OB0002X3CA">350</mezo>   -> again 3CA  should appear here, 
 sum of 300 + 50



The tag "OB001X1CA"  should frame in such a way that,
POINT1 : The number appearing before 'CA' should reset after every two 
records
POINT2 : The number appearing before 'X' should be same and need to 
increment by 1 for every two records.
like 001,001 then 002,002 then 003....

with my current logic iam getting  required out put

<mezo eazon="OB0001X1CA">200</mezo>
<mezo eazon="OB0001X2CA">150</mezo>
<mezo eazon="OB0002X1CA">300</mezo>
<mezo eazon="OB0002X2CA">50</mezo>


BUT , now i want to show the  sum of every two records,

here is my logic,

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; >
<xsl:key name="group" match="G_REP_TRX_DETAIL_INFO"

<xsl:output  method="xml" indent="yes" omit-xml-declaration="yes"/>
 <xsl:template match="/">
<xsl:apply-templates select=".//LIST_G_REP_TRX_DETAIL_INFO"/>
  </xsl:template>
  <xsl:template name="Temp1" match="LIST_G_REP_TRX_DETAIL_INFO">
 <xsl:for-each select="G_REP_TRX_DETAIL_INFO[C_TAX_REPORTING_NAME = 
'01'][generate-id()=generate-id(key('group',concat(C_BILLING_TP_TAX_REG_NUM,C_TAX_REPORTING_NAME))[1])]"><xsl:sort 
select="C_TAX_REPORTING_NAME"/>
 <mezo eazon="OB{format-number((position()+1) idiv 
2,'0000')}X{(((position()+1) mod 2) + 1)}BA"><xsl:value-of 
select="C_BILLING_TP_TAX_REG_NUM"/>
 </mezo><xsl:text>&#xD;</xsl:text>
 <mezo eazon="OB{format-number((position()+1) idiv 
2,'0000')}X{(((position()+1) mod 2) + 1)}CA"><xsl:value-of 
select="sum(key('group', 
concat(C_BILLING_TP_TAX_REG_NUM,C_TAX_REPORTING_NAME))/C_FUNCTIONAL_TOTAL)" 
/></mezo><xsl:text>&#xD;</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
