So, I'm not much of a Python programmer, but I wrote this Planet Venus filter that looks at each entry, and if it detects that it's a Jaiku presence update, it only includes it if it originated via Jaiku. In other words, it filters out all the duplicates.

If you understood any of that, you may find this helpful. If not, nevermind.


"""
For jaiku presence entries, only retain entries that originate from jaiku
(as opposed to grabbed via web feeds)
"""
import sys, xml.dom.minidom
entry = xml.dom.minidom.parse(sys.stdin).documentElement
entry_id = entry.getElementsByTagName('id')[0].firstChild.data
for node in entry.getElementsByTagName('link'):
if node.getAttribute('rel') == 'alternate':
entry_link = node.getAttribute('href')
break
if entry_id.find('jaiku.com/presence') > 0 and (entry_id != entry_link):
sys.exit(1)
print entry.toxml('utf-8')
