[Twisted-Python] domish.Element.__getattr__() or xpath.XPathQuery

[Gabriel Rossetti]

Hello everyone,

I was wondering what you would recommend, accessing nodes via 
domish.Element.__getattr__()
(e.g. el.node1.node1_1, where el is /msg) or via xpath.XPathQuery()
(e.g. xpath.XPathQuery("/msg/node1/node1_1").queryForNodes(el)[0])?

I was wondering which would be faster, the __getattr__() is O(n) (in my 
example there are 2 calls) but what about xpath.XPathQuery()?

Thank you,
Gabriel
