Question

1.i published a content to a node then use "spark" try to retrieve the message. in spark, i suppose to add user "admin@userx" right? i cannot get any message. below message showed, i sucessfully published the content to 'thenode'

<iq id="ySmn5-0" to="userx/3f3ae10c" type="result"><bind xmlns="urn:ietf:params:xml:ns:xmpp-bind"><jid>admin@userx/Smack</jid></bind></iq>
<iq id="ySmn5-1" to="admin@userx/Smack" type="result"></iq>
<iq id="ySmn5-2" to="admin@userx/Smack" type="result"><query xmlns="jabber:iq:roster"><item jid="test" name="test" subscription="none"></item><item jid="test@userx" subscription="from"></item></query></iq>
<message id="admin@userx__admin@userx__WIgPe" to="admin@userx" from="admin@userx"><event xmlns='http://jabber.org/protocol/pubsub#event'&gt;&lt;items node='null'><item id='thenode'/></items></event></message>
