Hi, I'm having trouble getting namespaced documents to work. I have this (test) schema:
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema xsd:targetNamespace="http://carfax.org.uk/namespace"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <xsd:complexType name="sthType"> <xsd:attribute name="foo" type="xsd:string"/> </xsd:complexType> <xsd:element name="something" type="sthType"/> </xsd:schema> and this XML document, which should, I believe, conform to the schema: <?xml version="1.0" encoding="UTF-8"?> <something xmlns="http://carfax.org.uk/namespace"; foo="bar"> </something> I've generated a module (PyXB 1.2.4): $ pyxbgen -u schema.xsd -m sth Python for AbsentNamespace0 requires 1 modules and I'm now trying to open the document: #!/usr/bin/python3 import sth doc = sth.CreateFromDocument(open("doc.xml", "r").read()) print(doc) This gives me: $ ./test Traceback (most recent call last): File "/usr/local/lib/python3.4/dist-packages/pyxb/namespace/__init__.py", line 307, in categoryMap return self.__categoryMap[category] KeyError: 'elementBinding' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "./test", line 5, in <module> doc = sth.CreateFromDocument(open("doc.xml", "r").read()) File "/home/hrm/rostercare/temp/sth.py", line 62, in CreateFromDocument saxer.parse(io.BytesIO(xmld)) File "/usr/lib/python3.4/xml/sax/expatreader.py", line 107, in parse xmlreader.IncrementalParser.parse(self, source) File "/usr/lib/python3.4/xml/sax/xmlreader.py", line 123, in parse self.feed(buffer) File "/usr/lib/python3.4/xml/sax/expatreader.py", line 207, in feed self._parser.Parse(data, isFinal) File "/usr/lib/python3.4/xml/sax/expatreader.py", line 341, in start_element_ns AttributesNSImpl(newattrs, qnames)) File "/usr/local/lib/python3.4/dist-packages/pyxb/binding/saxer.py", line 324, in startElementNS element_binding = name_en.elementBinding() File "/usr/local/lib/python3.4/dist-packages/pyxb/namespace/__init__.py", line 104, in __getattr__ category_value = ns.categoryMap(name).get(self.localName()) File "/usr/local/lib/python3.4/dist-packages/pyxb/namespace/__init__.py", line 309, in categoryMap raise pyxb.NamespaceError(self, '%s has no category %s' % (self, category)) pyxb.exceptions_.NamespaceError: http://carfax.org.uk/namespace has no category elementBinding Now, I'm guessing that the problem is indicated with the "Python for AbsentNamespace0 requires 1 module" message from pyxbgen, but I'm at a loss to see what the problem is. The only concern I have, which is more likely to be a basic XML question than a PyXB-specific one, is that only the elements in the schema are namespaced, not the attributes, with the exception of the xsd:targetNamespace attribute. I can't get pyxbgen to run with xsd: namespaces on the attributes of the schema, nor with the xsd: namespace missing from the xsd:targetNamespace attribute. This confuses me somewhat, in my primitive understanding of XML Schema. What am I doing wrong in all of this? Thanks, Hugo. -- Hugo Mills | The problem with programmers and the law is not that hugo@... carfax.org.uk | they treat laws as code, but that they don't http://carfax.org.uk/ | understand the VM it runs on.
