Subject: Help with staregies for outputting an incremental number in xslt

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>

<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....

Adam
