[pyxb-users] validation errors not as described

[<py...@ra...>]

hi,

i've just installed pyxb-1.2.3 into python-2.7
(via macports) on macosx-10.6.8 to validate xml
documents against an xsd file but the validation
errors that i'm seeing are not the nice informative
ones as described in:

  http://pyxb.sourceforge.net/userref_validating.html

instead of seeing line/column numbers and element names,
i'm seeing:

  pyxb.exceptions_.SimpleFacetValueError:
  Type <class 'sampleschema.STD_ANON_12'> minLength constraint violated by value

btw, the code supplied in the url above assumes that the exception
will be pyxb.UnrecognizedContentError but pyxb.exceptions_.SimpleFacetValueError
doesn't seem to be a subclass of that.

any idea what i've done wrong?

i generated the module with:

  $ pyxbgen -u sample-schema.xsd -m sampleschema
  Python for AbsentNamespace0 requires 1 modules

and the client code is:

  import sys, pyxb, sampleschema
  if len(sys.argv) != 2:
      print('usage: %s sample.xml' % sys.argv[0])
      exit(0)
  xmlbytes = open(sys.argv[1]).read()
  xmlparsed = None
  try:
      xmlparsed = sampleschema.CreateFromDocument(xmlbytes)
  except pyxb.UnrecognizedContentError as e:
      print('Error validating XML\n%s' % e.details())
  except Exception as e:
      print('Unknown XML validation error\n%s\n%s' % (type(e), e.details()))

which outputs:

  Unknown XML validation error
  <class 'pyxb.exceptions_.SimpleFacetValueError'>
  Type <class 'sampleschema.STD_ANON_12'> minLength constraint violated by value 

also, am i right in thinkng that there is no way to obtain
a list of all validation errors in a document (like xmllint)?

thanks,
raf
