This is the Python equivalent of the Java question How to output a CDATA section from a Sax XmlHandler
Neither xml.sax.saxutils.XMLGenerator or lxml.sax.ElementTreeContentHandler says anything about CDATA sections. How can I get it to output CDATA?

You could do it straight in your code using
from xml.sax.saxutils import XMLGenerator
xml = XMLGenerator()
xml.startDocument()
xml.startElement('item', {})
content = '<p>Stuff</p>'
cdata = '<![CDATA[{}]]>'.format(content)
xml.ignorableWhitespace(cdata)
xml.endElement('item')
xml.endDocument()
Or extend the XMLGenerator class with a new function
from xml.sax.saxutils import XMLGenerator
class _XMLGenerator(XMLGenerator):
def cdata(self, content):
cdata = '<![CDATA[{}]]>'.format(content)
self.ignorableWhitespace(cdata)
xml = _XMLGenerator()
xml.startDocument()
xml.startElement('item', {})
content = '<p>Stuff</p>'
xml.cdata(content)
xml.endElement('item')
xml.endDocument()
The reason I don't use xml.characters(content) is because it calls the xml.sax.saxutils.escape function, which in turns escapes &, < and >.

You can use xml.dom.minidom like this:
doc = xml.dom.minidom.Document()
article = doc.createElement('article')
content = doc.createCDATASection('<p>Any CDATA</p>')
article.appendChild(content)

Yes, the
Document.createCDATASection() method works, but it is missing from the documentation: docs.python.org/3/library/xml.dom.html#document-objects.
