See: http://www.rexx.com/~dkuhlman/generateDS.html#user-methods Make the following change to generateDS.py. Then, I believe that it will give you what you are asking for: # ----------------------------------------------------------------- --- Tmp/generateDS.py 2009-07-09 08:42:22.000000000 -0700 +++ generateDS.py 2009-07-09 08:41:05.000000000 -0700 @@ -3085,7 +3085,7 @@ else: s1 = 'class %s%s(GeneratedsSuper):\n' % (prefix, name) wrt(s1) - if UserMethodsModule: + if True: generateMemberSpec(outfile, element) wrt(' subclass = None\n') superclass_name = 'None' # ----------------------------------------------------------------- Here is a comment that explains a bit about what that change will cause generateDS.py to produce: # # Generate a class variable whose value is a list of tuples, one # tuple for each member data item of the class. # Each tuble has 3 elements: (1) member name, (2) member data type, # (3) container/list or not (maxoccurs > 1). OK, so actually, it generates a list of instances that are effectively 3-tuples. Here is an example -- Something like the following is added to each generated class: _member_data_items = [ _MemberSpec('Size', 'xs:integer', 0), _MemberSpec('Code', 'xs:string', 0), _MemberSpec('Name', 'xs:string', 0), o o o ] Would a dictionary in which you could do a look-up by member name be more convenient? If this is what you need and you think this might be generally useful, I'll add a command line option so that you can generate this even when you do not want the user methods stuff. > Hope that makes some kinda sense. ;-) Hope my reply does, too. - Dave -- Dave Kuhlman http://www.rexx.com/~dkuhlman ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
