First good job setting up such a nice tool.

I have an issue with the schema for ubl invoices, it works for ubl 2.0 but not ubl 2.1

here you have the schema

and I have this exception when I try to import the module generated by pyxbgen

  File "/home/malik/fteam_project/Fteam/utils/ubl/", line 1, in <module>
    from utils.ubl.ubl21 import invoice as ubl_invoice
  File "/home/malik/fteam_project/Fteam/utils/ubl/ubl21/", line 27, in <module>
    import utils.ubl.ubl21._cac as _ImportedBinding_utils_ubl_ubl21__cac
  File "/home/malik/fteam_project/Fteam/utils/ubl/ubl21/", line 27, in <module>
    import utils.ubl.ubl21._cbc as _ImportedBinding_utils_ubl_ubl21__cbc
  File "/home/malik/fteam_project/Fteam/utils/ubl/ubl21/", line 28, in <module>
    import utils.ubl.ubl21._udt as _ImportedBinding_utils_ubl_ubl21__udt
  File "/home/malik/fteam_project/Fteam/utils/ubl/ubl21/", line 27
    import utils.ubl.ubl21._ccts-cct as _ImportedBinding_utils_ubl_ubl21__ccts_cct
SyntaxError: invalid syntax

I generated this module this way:

pyxbgen -u ../extra/ -m invoice --module-prefix=utils.ubl.ubl21
WARNING:pyxb.binding.generate:Complex type {urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2}ContractingPartyType renamed to ContractingPartyType_
Python for urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 requires 13 modules

is it safe to just rename the module ?
if yes how does it impact the rest of the generated code ?


ps: I renamed it with an underscore instead of the dash and it seems to work fine

Yes, if you rename the module in the file system and in all import statements it should work fine. Next time I'm working PyXB I'll get a patch in to do this automatically. Thanks for reporting the problem.

For my reference when replicating:

wget -r -l2

@pabigot fix #48: invalid import syntax
Ensure that all components of a module path are valid as Python
identifiers so that the module can be imported.
