[lxml-dev] lxml.objectify.deannotate refuses to clean nil nodes

[Robert Pierce]

The nil node <Fubar/> is not deannotated as I would expect in the following
snippet.  I could not find a reference to this behaviour in the archives or
documentation.  Is this a design feature for which there is a work around,
or a bug?  I'm using lxml-2.2-py2.5-linux-i686.

Thanks!

#### CODE ####

import lxml.etree
import lxml.objectify

x = lxml.objectify.fromstring('<root><Bar/></root>')
x.Foo = ''
x.Fubar = None
lxml.objectify.deannotate(x)
lxml.etree.cleanup_namespaces(x)
print lxml.etree.tostring(x)

#### END CODE ###

<root><Bar/><Foo></Foo><Fubar xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/></root>
