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

[Peter Doggett <ee99ppd at brunel dot ac dot uk>]

Ok cheers David.

I actually Have a template match to root '/' and then 
within this a <for-each> on all of the register nodes which 
calls the template .

To rule out the possibility of my template being called in 
the wrong place i did a few sanity checks when it was 
called -  like to display the current @name of the register
and also some details of the first Bitfield[1] etc...
(shifter has also been tested independantly and returns 
valid results).

I mean looking at the choose statement itself, should this 
behave as you can see -  by processing up to and including 
the last <bitfield> node, and then stopping displaying the 
results?

Is there any problems that spring to your mind that I can 
explore? The only conclusive problem that I can see is the 
<choose> statement is not valid, but again I have reviewed 
a lot of material and the conditional statement seems to be 
what I need?


Thankyou 

PD
