Note, Jarno, the sorting that the original poster is doing.

Using xsl:for-each you don't; if you process the txns using a recursive template construct, you can always pass the previous currCpmBI, but not using xsl:for-each - it's *not* a for-loop like in, say, Java. Instead just do

<xsl:if test="cpmMemBI = previous-sibling::txns[1]/cpmMemBI">

This will visit the source node tree in document order, and not in sorted order.

Unless I'm missing something (easily possible early on a Monday morning), I'm not convinced a recursive template addressing nodes in document order is going to quite address the poster's needs to know the "previous" node in sorted order.

I hope this helps.
