Peter,
thanks a lot for your quick and really effectual help. I have extended your
script with all required elements and I'm now able to produce valid XML
document without having:
pyxb.RequireValidWhenGenerating(False)
Thank you very much. Saved me a lot of time. May I have another two questions?
1. How can I add information about encoding, I'd like to have it utf8.
<?xml version="1.0" encoding="UTF-8"?>
2. How can I work with utf8 characters within my script? It doesn't work for
me. My test is:
ivh.text = 'Unicode test ěščřžýáíé'
which ends with error:
Traceback (most recent call last):
File "sf.py", line 20, in ?
ivh.text = 'Unicode test ěščřžýáíé'
File "/usr/lib/python2.4/site-packages/pyxb/binding/basis.py", line 62, in
__setattr__
return super(_TypeBinding_mixin, self).__setattr__(name, value)
File "/usr/lib/python2.4/site-packages/pyxb/binding/content.py", line 521, in
set
value = self.__elementBinding.compatibleValue(value,
is_plural=self.isPlural())
File "/usr/lib/python2.4/site-packages/pyxb/binding/basis.py", line 1339, in
compatibleValue
return self.typeDefinition()._CompatibleValue(value, **kw)
File "/usr/lib/python2.4/site-packages/pyxb/binding/basis.py", line 270, in
_CompatibleValue
return cls(value)
File "/usr/lib/python2.4/site-packages/pyxb/binding/basis.py", line 684, in

args = cls._ConvertArguments(args, kw)
File "/usr/lib/python2.4/site-packages/pyxb/binding/basis.py", line 662, in
_ConvertArguments
norm_str = unicode(cf_whitespace.normalizeString(args[0]))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 13:
ordinal not in range(128)
Thanks,
David Hrbac
