Subscribing
Now that Marty has discovered these two useful nodes, he will need to subscribe to them. This is done rather simply, using the following stanzas:
<iq type='set' id='sub1'
from='marty@mcfly.fam/street'
to='pubsub.hill.valley'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<subscribe node='storm-updates' jid='marty@mcfly.fam'/>
</pubsub>
</iq>
<iq type='set' id='sub2'
from='marty@mcfly.fam/street'
to='pubsub.hill.valley'>
<pubsub xmlns='http://jabber.org/protocol/pubsub'>
<subscribe node='doc-brown-weather-experiment'
jid='marty@mcfly.fam'/>
</pubsub>
</iq>
The subscription requests come back almost immediately:
<iq type='result' id='sub1'
from='pubsub.hill.valley'
to='marty@mcfly.fam/street'>
<pubsub xmlns='http://jabber.org/protocol/pubsub>
<subscription...
