OK, lets try to get a position of the first occurrence when var2 = max node.
As I said, I don't want to change the order of the nodes in a tree with sort.
What would be a correct syntax ?

<xsl:for-each select=mystruct/myarray1[1]/myvar>
  <xsl:if var2=*[last()]>
    <xsl:value-of select="position()">
  </xsl:if>
</xsl:for-each>

The goal is to trim the table [see my previous post],
get rid of multiple identical occurrences of rebate1 & rebate2.

Do you understand me ?

Thank you,
Oleg.
