[xsl] Re: count(preceding-sibling ) not working

Thanks...

Yes of course, sorry for being so thick. I see that and understand the problem. But I am having 
trouble finding a solution:



What I want to do is to count the total number of Accrual nodes that precede the current Accrual 
node. Both the siblings of the current Accrual node and any Accrual children of all preceding 
Accruals nodes.




I have tried this:



<xsl:for-each select="expensys:Lines/expensys:Line/expensys:Accruals/expensys:Accrual">



<txn:PSIBS>
  <xsl:number value="count(preceding-sibling::*)"/>
</txn:PSIBS>


I cannot use a filter on the for-each loop 'cos AFAICS this would mean restructuring the whole 
transform. With my current level of XSL knowledge that would take an unacceptably long time :-)




Many thanks for any help....




Adam

What am I doing wrong?

well you haven't shown any sopurce code, so we have to guess, but
presumably you get 0 bcause there are no preceding siblings.
that is children of the same parent.  If each Accruals element just has
a single Accrual child, then that will be the case.



I know could use "position()", but after I solve this problem I need to apply a filter to the PSIBS 
value.




Most likely you just need to do the filter before you use position.




<xsl:for-each
select="expensys:Lines/expensys:Line/expensys:Accruals/expensys:Accrual[some
filter goes here">

<txn:PSIBS>
<xsl:value-of select="position()"/>
</txn:PSIBS>
