RE: [xsl] Repeated Recursion on different parts of a tree

[Peter Doggett <ee99ppd@xxxxxxxxxxxx>]

Ok thanks James.

I am aware of the call-template tag.

However the issue I have was with the fact that 
if I was to call the template by name, how would I deal 
with the fact that I want to use the first <bitfield> node, 
and then the next and then the next etc.. with each pass of 
recursion?

Below it is done by the select attribute, which 
<call-template> does not have?

Thanks for the book reference. I have just ordered 
Michael Kays XSLT Programmers reference, but I may add that 
to my shopping list to.


Thanks


PD
