Re: [xsl] Way to print the current context?

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hello,

Just adding the obvious point that if you write yourself a function or set
of templates to write an XPath (as Dmitre has done) you can also tune it to
write better paths ('better' being relative to your case).

Templates make this pretty easy too and a nice exercise for
beginner-intermediates.

Regards, Wendell
