Re: [xsl] for-each loop question

["Mukul Gandhi" <gandhi.mukul@xxxxxxxxx>]

There is a good explanation about Piez method at
http://www.dpawson.co.uk/xsl/sect2/muench.html (topic number 7).
//node() is one node-set which I mentioned. As mentioned in the FAQ,
you can use the expression / | //node() | //@* | //namespace::* to
increase the number of nodes.
