Summary: PrettyPrint with UTF-16 encoding produces invalid XML.
Initial Comment:
Every string written to the output stream by
PrettyPrint() has the default BOM prefixed to it.
Using the UTF-16LE encoding stops any BOM from
appearing in the output stream, including before the
XML declaration. This means that the resultant XML is
not valid (section 4.3.3 XML 1.0 3e).
Element attribute output is also invalid. The =" and
final " are not encoded so end up pairing up with bytes
from the BOM codepoint. Using UTF-16LE does not
correct the output for similar reasons.
I assume UTF-32 output will suffer from the similar
problems.
PyXML version 0.8.4 and Python version 2.4.1
Example code:
dom = Document.Document(None)
element = dom.createElement('HelloWorld')
element.setAttribute('Language', 'English')
dom.appendChild(element)
PrettyPrint(dom, stream=file('./pp.xml', 'w+b'),
encoding='UTF-16')
