[Python-bugs-list] [Bug #116677] minidom:Node.appendChild() has wrong semantics

[noreply@sourceforge.net]

Bug #116677, was updated on 2000-Oct-11 19:24
Here is a current snapshot of the bug.

Project: Python
Category: Library
Status: Open
Resolution: None
Bug Group: None
Priority: 7
Summary: minidom:Node.appendChild() has wrong semantics

Details: Consider this test program:

from xml.dom import minidom
doc = minidom.Document()
root = doc.createElement('root') ; doc.appendChild( root )

elem = doc.createElement('leaf')
root.appendChild( elem )
root.appendChild( elem )

print doc.toxml()
print root.childNodes

It prints:
<root><leaf/><leaf/></root>
[<DOM Element: leaf at 135586476>, <DOM Element: leaf at 135586476>]

'elem' is now linked into the DOM tree in two places, which is wrong; according to the DOM Level 1 spec, 
"If the newChild is already in the tree, it is first removed."
