PythonElementClassLookup
PythonElementClassLookup(self, fallback=None)
Element class lookup based on a subclass method.
To use it, inherit from this class and override the lookup method to
lookup the element class for a node:
lookup(self, document, node_proxy)
The first argument is the opaque document instance that contains the
Element. The second arguments is a lightweight Element proxy
implementation that is only valid during the lookup. Do not try to keep a
reference to it. Once the lookup is done, the proxy will be invalid.
If you return None from this method, the fallback will be called.
