Hi,

I am trying to reassign variables in XSLT.

I know how to declare them :
<AP-TR-REFERENCE>
<xsl:variable name="g_CBA_HL1" expr="0"/>

<xsl:for-each select="a:message/a:COMMAND/a:proposePersonalLoanArrangementRequest/a:involvedPartyRole/a:involvedParty/a:financialStatement/a:income/a:item">
<xsl:choose>
<xsl:when test="$g_CBA_HL1 = 0">
<xsl:value-of select="a:value"/>
<xsl:value-of select="$g_CBA_HL1 = number($g_CBA_HL1) + number(a:value)"/>

</xsl:when>
<xsl:otherwise>

</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</AP-TR-REFERENCE>

Hi Sean,

Variables in the XSLT are immutable, once the value is assigned can not be changed.

To implement a counter you will need to write a recursive template.

In this particular case it seems that you are trying to sum a numeric value so you could try the sum function.

<xsl:value-of select="sum(a:message/a:COMMAND/a:proposePersonalLoanArrangementRequest/a:involvedPartyRole/a:involvedParty/a:financialStatement/a:income/a:item)"/>

Hope this helps
Ivan

Hi Ivan,

Thx for your reply. Yes i thought that was the case with variables.

My understanding is that the sum function wil sum all the nodes in the nodeset however I need to be selective eg if the loop contained :

Item Value
A 10
B 5
C 7
D 4
E 9

I'm only interested in eg the value for A and D which I will then sum up.
Thx Sean

Assume to have the following XML in input

<?xml version="1.0"?>
<ROOT>
<A>10</A>
<B>5</B>
<C>7</C>
<D>4</D>
<E>9</E>
</ROOT>

The following XSLT sum A and D

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="sum(/ROOT/A | /ROOT/D)"/>
</xsl:template>
</xsl:stylesheet>

Hope this helps
