Hi all,
YAQ (Yet Another Question):
Following the general pattern, I end up with a Body object which has
an attribute .nodes that consists of a list of Node objects.
So, something like:
My Example Body
Node List
Node the first
Node the second
Is there any way to make methods of the Node class access attributes
of `parents' of instances? I would like a Node instance such as Node
the first above to be aware just what it is a node of and what its
siblings are.
Does this make sense?
Best to all,
Brian vdB
PS Thanks for the reply to my venting question, Kent.
