Is there a reason why UNL's don't keep the number of nodes with the
same node inside its string?
Same way as xPath does? "Node name [number]->> Node
name[Number]-->"
Only that multiple same name nodes hasn't come up enough for it to get
implemented, but it's a good idea. I'm thinking it's not worth trying
to find a syntax which avoids breaking with nodes called "foo[7]", they
can't be that common and we don't avoid breaking on nodes called
"foo-->bar", so might as well keep it simple.
So I would propose the syntax is simply [N] appended immediately after
the node number
so
import re
pos_pattern = re.compile(r'\[(\d+)]$')
and then while processing each level of the UNL
unl_part = 'test[22]'
pos = pos_pattern.search(unl_part) or 0
if pos:
pos = int(pos.group(1))
unl_part = pos_pattern.sub('', unl_part)
and search the current node for the pos'th child called unl_part

Perhaps an even more uncommon character could be chosen? Such as ‡N‡ ?
Just a thought.
