[XML-SIG] c14n.py bug: _IN_XML_NS = lambda n: n.namespaceURI == XMLNS.XML
Thu, 23 Jan 2003 22:30:48 -0500
A bug is fixed if I comment out present line and include the subsequent:
# _IN_XML_NS = lambda n: n.namespaceURI == XMLNS.XML
_IN_XML_NS = lambda n: n.name[:5] == "xmlns"
_IN_XML_NS is used if an element is being inclusively canonicalized. (This
is *not* a full dom tree being tested against a XPath node-set) It's the
test to see whether the ancestors need to be crawled for the namespaces. As
'n' is typically an attribute node, in pyxml DOMs they don't even have a
namespaceURI attribute, so they are never included.
I noted this bug becaue I use xml.dom.ext.Canonicalize in .
