Subject: Get Items from PubSub Subscription

I'm looking the best way to get the items after I've subscribed to a pub sub node. I'm receiving the message in the pubSubManager OnEvent, but there is no data in the MessageEventArgs e, Message, Body Property.

Do I have to walk through the nodes, or should I use some object that is already in the SDK to get the data?

Any quick code examples would be helpful in C#.

Thanks,

Morgan

A pubsub notification message with payload look like the following:

<message from='pubsub.shakespeare.lit' to='francisco@denmark.lit' id='foo'>
  <event xmlns='http://jabber.org/protocol/pubsub#event'>
    <items node='princely_musings'>
      <item id='ae890ac52d0df67ed7cfdf51b644e901'>
        <entry xmlns='http://www.w3.org/2005/Atom'>
          <title>Soliloquy</title>
          <summary>
To be, or not to be: that is the question:
Whether 'tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing end them?
          </summary>
          <link rel='alternate' type='text/html'
                href='http://denmark.lit/2003/12/13/atom03'/>
          <id>tag:denmark.lit,2003:entry-32397</id>
          <published>2003-12-13T18:30:02Z</published>
          <updated>2003-12-13T18:30:02Z</updated>
        </entry>
      </item>
    </items>
  </event>
</message>

You should be able to loop over the items with the following code:

foreach (var item in e.Message.Element<Event>().Items.GetItems())
{
                
}
