I am parsing some XML using Pyxb and a required attribute is not available in the XML. I catch the MissingAttributeError exception which tells me:

Instance of <class 'TestXML.TEST.CTD_ANON_27'> lacks required attribute how

My question is, even though a required attribute is missing from the XML data, is there a way to still parse this XML data even though this attribute is missing? The rest of the XML data is valid and still useful.

You can disable validation. Something like the following (excerpt from the test suite):

xmls = '<Element/>'
pyxb.RequireValidWhenParsing(True)
self.assertRaises(MissingAttributeError, CreateFromDocument, xmls)
pyxb.RequireValidWhenParsing(False)
self.assertFalse(pyxb._ParsingRequiresValid)
instance = CreateFromDocument(xmls)

Note that PyXB is not intended to support processing invalid documents, so the generated binding may not fully reflect the content of the XML.
