New submission from Denis S. Otkidach <denis.otkid...@gmail.com>:
ElementTree and minidom allow creation of not well-formed XML, that
can't be parsed:
>>> from xml.etree import ElementTree
>>> element = ElementTree.Element('element')
>>> element.text = u'\0'
>>> xml = ElementTree.tostring(element, encoding='utf-8')
>>> ElementTree.fromstring(xml)
[...]
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 1,
column 9
>>> from xml.dom import minidom
>>> doc = minidom.getDOMImplementation().createDocument(None, None, None)
>>> element = doc.createElement('element')
>>> element.appendChild(doc.createTextNode(u'\0'))
<DOM Text node "">
>>> doc.appendChild(element)
<DOM Element: element at 0xb7ca688c>
>>> xml = doc.toxml(encoding='utf-8')
>>> minidom.parseString(xml)
[...]
xml.parsers.expat.ExpatError: not well-formed (invalid token): line 1, colum
I believe they should raise some exception when there are characters
not allowed in XML (http://www.w3.org/TR/REC-xml/#NT-Char) are used in
attribute values, text nodes and CDATA sections.
