cElementTree implements the interfaces described here:
http://www.effbot.org/zone/element.htm
Comment support may be added in a future release. In the meantime,
you can work around this limitation by creating a cElementTree node,
and setting the "tag" attribute to ElementTree.Comment:
>>> import cElementTree
>>> from elementtree.ElementTree import Comment
>>> x = cElementTree.Element(Comment)
>>> x.text = "hello"
>>> cElementTree.tostring(x)
'<!-- hello -->'
I recommend wrapping this functionality in a helper function that looks
for cElementTree.Comment, and only uses the workaround if necessary:
def makecomment(text):
try:
elem = cElementTree.Comment(text)
except AttributeError:
elem = cElementTree.Element(ElementTree.Comment)
elem.text = text
return elem
</F>
