Re: [xsl] xsl recursion

[Norman Barker <normanb@xxxxxxxxxxxxx>]

My apologies, wasn't aware of the cross post, I waited all afternoon for
my message to appear in comp.text.xml, it didn't so I posted to mulberry
(check the times if you don't believe me!).  I was trying to do an
algorithm with an XML fragment (since I am using SAX withing Cocoon)
so /*/* won't work in my case, I will try with the stop position you
suggest.

Thanks for all your help, and apologies about the cross post.
