Re: RE: [xsl] sequence numbering.

["william locksman" <vsd18 at rediffmail dot com>]

Hi the solution Michael Suggested seems to fit my purpose, But 
Since i am a newbie to XSL , I do not know how to form a temporary 
tree that contains sorted sequence.
Michael's explaination made me pretty much clear of what has to be 
done. But i do not know how it has to be done.
If any one can please suggest me how to go about doing it or give 
me a link to any reference document, It should be of much help to 
me
Thanks
William
