Just thought it might be worth posting the code I have started to play around
with. Nothing special but I think it might be modifiable to work, and it
could serve as a reasonable starting point. The basic approach is as
described in my first post, open a document, get the numbering system
object, get the paragraphs and iterate through them. For each para, try to
get the numID. If that returns null then the paragraph is not in a list, if
a BigInteger object is returned then the para is in a list. If the para is
in a list, check to see that we are not already processing that list - if we
are then this is where concerns around levels and incrementing numbers can
be handled. Also, if the para is in a list and it is a 'new' list, get the
numbering system information. Lots of details to work out but it gets us
onto the first rung of the ladder I think.
