[jdev] questions using pubsub

[Orion]

Hi,

I am new to jabber, using ejabberd 0.9.1 and Psi.

I am able to create a node and publish an item.
for example: 
=======================================================
<iq type="set"
    from="admin at localhost"
    to="pubsub.localhost"
    id="publish1">
  <pubsub xmlns="http://jabber.org/protocol/pubsub">
    <publish node="home/localhost/admin/egw">
      <item id="current">
        <tune xmlns="http://jabber.org/protocol/tune">
          <artist>Ralph Vaughan Williams</artist>
          <title>Concerto in F for Bass Tuba</title>
          <source>Golden Brass: The Collector's Edition</source>
        </tune>
      </item>
    </publish>
  </pubsub>
</iq>
=======================================================

I found that subscribers can only view the message in XML console. My question
is: How can the subscribers get the published item like normal chat
message(signal the subscriber for incoming message)?

Thanks.

Orion
