Re: [bdbxml] XmlManager.openContainer

Just a thought...

container = manager.openContainer("rssfeeds.dbxml")

Make sure you're being explicit as to the location of your dbxml file.
 The openContainer() method is probably looking in the current working
directory for your dbxml file.

I was having symptoms like yours but fixed it with something like:

container = manager.openContainer("/xmldata/containers/rssfeeds.dbxml")

or where ever your dbxml containers are.
