Re: [xsl] Help to construct a loop

[henry human <henry_human@xxxxxxxx>]

I know doXslTransform and because of that I tried to
ask in this XSL list. 
I changed my idea and will use however doXslTransform
but there are some obstacle to use it in my bpel
process..

I am agreeing with you that it is rather an xPath and
xQuery issue than the XSL.
I mixed both together!
Thank you
