Re: How can I conditionaly assign a node-set to my variable?

Use:

       channel[6 > id or id='P'] [6 > $n and $hasP]
   | 
       channel[6 > id] [not(6 > $n and $hasP)]


Of course, in XPath 2.0 one can simply use a conditional expression:

       if(expression)
         then expression 
         else expression
