xalan xsl:sort does not sort!

Hi

 

            I’m using Xalan and trying to sort blocks of element but without success.

 

            I’m trying to sort each block of NetPrice element by the attribute NetAmount.  In each ProductOption, I have multiple NetPrice element

 

            Check my example below.

 

Thanks for your help

Stephane
