Probably. Also each of Element.attributes if there are any attributes
in the object, and Node.namespaceURI if the document uses namespaces.

DOM Level 3 Core defines the method Node.isEqualNode:

  http://www.w3.org/TR/DOM-Level-3-Core/core.html#Node3-isEqualNode

Which would do such a comparison. minidom doesn't support it yet, but
pxdom does. Otherwise, it's not too much work to write a recursive
comparator such as the above.

(The Python == operator does the same as DOM3's Node.isSameNode, or
'is'.)
