I'm dealing with a third party XSD schema to generate python classes. The application will parse XML files to extract data. It's not about creating xml files. The generated code works fine when parsing any valid `xml` data file.
Anyway the results differ somewhat than expected. I got about 50 class names which look like CTD_ANON... I guess this is due to the extensive use of anonymous types in the schema. In turn I can not bind them because I don't know how to. On the other hand perhaps everything is because of my own ignorance. Well, I can not deny that either. In case someone is interested the complete xsd schema and other details here. https://bitbucket.org/emezeta/pyefuy So to generate the classes: $~ pyxbgen -u EnvioCFE_entreEmpresas.xsd -m eceelib produces three files: _ds.py _xenc.py eceelib.py then: $~ python Python 2.7.9 (default, Jun 29 2016, 13:08:31) [GCC 4.9.2] on linux2 >>> >>> import eceelib >>> with open("./xml/Sob_111111111111_20161207_99999.xml") as f: ... xml_str = f.read() ... >>> xml_doc = eceelib.CreateFromDocument(xml_str) results in: Python 2.7.9 (default, Jun 29 2016, 13:08:31) [GCC 4.9.2] on linux2 >>> >>> import eceelib >>> with open("./xml/Sob_111111111111_20161207_99999.xml") as f: ... xml_str = f.read() ... >>> xml_doc = eceelib.CreateFromDocument(xml_str) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "eceelib.py", line 71, in CreateFromDocument saxer.parse(io.BytesIO(xmld)) File "/usr/lib/python2.7/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/usr/lib/python2.7/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/usr/lib/python2.7/xml/sax/expatreader.py", line 210, in feed self._parser.Parse(data, isFinal) File "/usr/lib/python2.7/xml/sax/expatreader.py", line 351, in end_element_ns self._cont_handler.endElementNS(pair, None) File "/usr/local/lib/python2.7/dist-packages/pyxb/binding/saxer.py", line 388, in endElementNS binding_object = this_state.endBindingElement() File "/usr/local/lib/python2.7/dist-packages/pyxb/binding/saxer.py", line 226, in endBindingElement self.__constructElement(self.__delayedConstructor, self.__attributes, args) File "/usr/local/lib/python2.7/dist-packages/pyxb/binding/saxer.py", line 116, in __constructElement self.__bindingInstance = new_object_factory(*content, **kw) File "/usr/local/lib/python2.7/dist-packages/pyxb/binding/basis.py", line 1613, in __call__ args = [ self.compatibleValue(args[0], **kw) ] File "/usr/local/lib/python2.7/dist-packages/pyxb/binding/basis.py", line 1635, in compatibleValue raise pyxb.ElementChangeError(self, value) pyxb.exceptions_.ElementChangeError: Value 2 for element {http://cfe.dgi.gub.uy}TipoDocRecep incompatible with fixed content >>> full ipython trace image http://bit.ly/2kSoRVa Then I slightly modified the "CFEType.xsd" file to deal with this issue despite '2' being the proper `fixed` value in both xsd schema and xml data file. My workarround on "CFEType.xsd" file was: < <xs:element name="TipoDocRecep" type="DGICFE:DocType" fixed="2"> --- > <xs:element name="TipoDocRecep" type="DGICFE:DocType"> # this line works Now the xml file is parsed smoothly. >>> xml_doc = eceelib.CreateFromDocument(xml_str) >>> As far as I can get things seems to go fine, This is a small experience with pyxb, hopefully useful. I'll be glad receiving any suggestion, insights, fixes to improve and learn or simply find a better way doing so. Thanks, emezeta ps: pyxb.exceptions_.ElementChangeError: exception as an issue can be seen here http://bit.ly/2kSQAoV
