Hello
Firstly, I am an inexperienced xslt user, so please forgive me if this a no-brainer.
My problem is this:
I have a list of nodes, and I need to output a node count with each node.
I use the position() function to output the node count. So far so good.
Recently however, the requirement has changed: under certain circumstances a node is ommited from
the output. When a node is ommitted, the node count of the subsequent node is incorrect - because
the position() function counts all nodes, including the omitted ones.
e.g.:
<xsl:for-each select="expensys:Lines/expensys:Line/expensys:Accruals/expensys:Accrual">
<xsl:variable name="description">
<xsl:value-of select="../../expensys:ItemDescription"/>
</xsl:variable>
<!-- Node ommission
Set includeLine=false for personal spend lines with CorpCardRec personal settlement
as we dont want to output these -->
<xsl:variable name="includeLine">
<xsl:choose>
<xsl:when test="$description = 'Personal Spend'">
<xsl:if test="$transactionType = 'CorporateCardReconciliation'"> <xsl:if
test="$corporateCardSettlementType = 'corporate'"> <xsl:value-of
select="true()"/> </xsl:if> <xsl:if
test="$corporateCardSettlementType = 'personal'"> <xsl:value-of
select="false()"/> </xsl:if>
</xsl:if>
<xsl:if test="$transactionType != 'CorporateCardReconciliation'">
<xsl:value-of select="true()"/>
</xsl:if>
</xsl:when>
<xsl:otherwise> <xsl:value-of select="true()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:if test="$includeLine='true'">
<txn:Line>
<txn:Number> <xsl:value-of select="position()"/>
<txn:Number>
<!-- More data from node is output here..... --!>
</txn:Line>
</xsl:if>
I need the value of txn:Number to increment contigously, but this recent node ommission has thrown a
spanner in the works :-(
I have searched through the forums and discovered its not possible to increment a variable in a
for-each loop. Can anyone guide me to a solution?.
Many thanks in advance....
