Ravi,
The reason that I want to use the EVDB feed is that the EVDB provide the Postal Address that the CNN does not.
The CNN provides only the <title>, <link>, <description>
While EVDB provides <title>, <link>, <geo Point>, <PostalAddress> and ...
Therefore using the EVDB XML will allow us to put the marker on the map and we can show the detail of the event on the marker.
However this is just an idea. I am not sure if we have enough time.
Thanks,
Nattakorn
