[xsl] problem with sum() function

["Pankaj Bishnoi" <pankaj.bishnoi@xxxxxxxxxxx>]

Hi All
         I am using sum() function with nodelist. Now my problem is that
when a source elemnt contains leading + sign then sum returns NAN. Is there
a way to remove this + sign and then calculate the sum. My source xml is::


<?xml version="1.0" encoding="ISO-8859-1"?>
<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<CLIENT_HEADER_RECORD_TYPE-HT><CLIENT_NUMBER><![CDATA[000832]]></CLIENT_NUMB
ER>
</CLIENT_HEADER_RECORD_TYPE-HT>
<EXPERIENCE_SETUP_CHANGE_RECORD_TYPE-ET><CLIENT_NUMBER><![CDATA[000832]]></C
LIENT_NUMBER>
<EXPERIENCE_SETUP_CHANGE_RECORD_TYPE><![CDATA[ET]]></EXPERIENCE_SETUP_CHANGE
_RECORD_TYPE>
<DATA_TYPE><![CDATA[DC]]></DATA_TYPE>
<EXPER_AMT_BY_RESERVE1><![CDATA[+000000000000565500]]></EXPER_AMT_BY_RESERVE
1>
</EXPERIENCE_SETUP_CHANGE_RECORD_TYPE-ET>
<EXPERIENCE_SETUP_CHANGE_RECORD_TYPE-ET><CLIENT_NUMBER><![CDATA[000832]]></C
LIENT_NUMBER>
<EXPERIENCE_SETUP_CHANGE_RECORD_TYPE><![CDATA[ET]]></EXPERIENCE_SETUP_CHANGE
_RECORD_TYPE>
<DATA_TYPE><![CDATA[DC]]></DATA_TYPE>
<EXPER_AMT_BY_RESERVE1><![CDATA[+000000000000505500]]></EXPER_AMT_BY_RESERVE
1>
</EXPERIENCE_SETUP_CHANGE_RECORD_TYPE-ET>
</Root>





My XSL is


<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.1" xmlns:java="http://xml.apache.org/xslt/java";
xmlns:str="http://exslt.org/strings";
xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect"
extension-element-prefixes="redirect">
     <xsl:output method="xml" version="1.0" encoding="ISO-8859-1"
indent="yes"/>

     <xsl:variable name="apos">'</xsl:variable>
     <xsl:template match="/">
          <Root>
               <xsl:apply-templates
select="/Root/CLIENT_HEADER_RECORD_TYPE-HT"
mode="_Root_Record_order1"></xsl:apply-templates>
          </Root>
     </xsl:template>
     <xsl:template match="/Root/CLIENT_HEADER_RECORD_TYPE-HT"
mode="_Root_Record_order1">
          <Record>
   <xsl:variable name="varClientNumber" select="CLIENT_NUMBER"/>
   <xsl:variable name="pankaj" select="sum(following-sibling::
EXPERIENCE_SETUP_CHANGE_RECORD_TYPE-ET[CLIENT_NUMBER=$varClientNumber and
DATA_TYPE='DC']/EXPER_AMT_BY_RESERVE1)"/>
  <Sum>$pankaj</Sum>
          </Record>
     </xsl:template>
</xsl:stylesheet>


and the output is ::



<?xml version="1.0" encoding="UTF-8"?>
<Root xmlns:java="http://xml.apache.org/xslt/java";
xmlns:str="http://exslt.org/strings";>
    <Record>
        <Sum>NaN</Sum>
    </Record>
</Root>







I also tried to use XSL temlates with recursion but that fails when we have
large set of data.

Thanks in advance for any help.

Thanks
