Python XML parser (xml.etree) does not seems to allow control characters that are invalid in XML 1.0, but valid in XML 1.1 [1] [2]


Considering the following sample:


import xml.etree.ElementTree as ET

bad = '<?xml version="1.1"?><foo>bar &#x19; baz</foo>'
print(ET.fromstring(bad))


The parser raises the following error:
ParseError: reference to invalid character number: line 1, column 30
