Newbie Question: can this snippet be optimized?
 

Hi Pythonians,

The underlying snippet is copied from minidom.py which is in the XML
package which I am currently using. Cloning nodes seem to take a
considerable amount of time, hence I went looking in the code whether
optimizations could be made. The following snippet contains a for
loop:

def cloneNode(self, deep):
clone = Node.cloneNode(self, deep)
clone._attrs = {}
clone._attrsNS = {}
for attr in self._attrs.values():
node = attr.cloneNode(1)
clone._attrs[node.name] = node
clone._attrsNS[(node.namespaceURI, node.localName)] = node
node.ownerElement = clone
return clone

I just wondered if this could be optimized (mao, array, whatever) and
if so, how? I do not have much experience with Python, hence the
question.

Thanks for suggestions,

Hedr

Try applying psyco.bind() to see if you can
get a substantial speed-up.
