XMPPFramework - Retrieve Archived Messages From Openfire Server
I am developing a chat app for iPhone using XMPP and openfire server,OpenFire server is storing all the chat history between users but When I try to retrieve the chat history for a particular user I get only the date and the number of chat messages but not the actual text messages
I have already installed open archive plugin for message archiving on openfire
This is the stanza which I have passed to Openfire Server
<iq type='get' id='pk1'>
<list xmlns='urn:xmpp:archive'
with='piyush@openfire'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>30</max>
</set>
</list>
</iq>
This is the result which I received from server
<iq type="result" id="pk1" to="vivek@openfire/iphone">
<list xmlns="urn:xmpp:archive">
<chat with="piyush@openfire" start="2012-07-04T13:16:12.291Z"/>
<chat with="piyush@openfire" start="2012-07-05T08:25:31.555Z"/>
<chat with="piyush@openfire" start="2012-07-05T12:38:24.098Z"/>
<set xmlns="http://jabber.org/protocol/rsm">
<first index="0">15</first>
<last>25</last>
<count>3</count>
</set>
</list>
</iq>
This is the result which I want and which I expected
<iq type='result' to='vivek@openfire/iphone' id='page1'>
<chat xmlns='urn:xmpp:archive'
with='piyush@openfire'
start='2012-07-04T13:16:12.291Z'
subject='She speaks!'
version='4'>
<from secs='0'><body>Art thou not Romeo, and a Montague?</body></from>
<to secs='11'><body>Neither, fair saint, if either thee dislike.</body></to>
.
[98 more messages]
.
<from secs='9'><body>How cam'st thou hither, tell me, and wherefore?</body></from>
<set xmlns='http://jabber.org/protocol/rsm'>
<first index='0'>0</first>
<last>99</last>
<count>217</count>
</set>
Please Help me out to get the desired result
Thanks

You have to do a request with <retrieve> (see http://xmpp.org/extensions/xep-0136.html) then you can take a specific time from the received <list> result. For example:
Send:
<iq type='get' id='pk1'>
<list xmlns='urn:xmpp:archive'
with='piyush@openfire'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>30</max>
</set>
</list>
</iq>
Receive:
<iq type="result" id="pk1" to="vivek@openfire/iphone">
<list xmlns="urn:xmpp:archive">
<chat with="piyush@openfire" start="2012-07-04T13:16:12.291Z"/>
<chat with="piyush@openfire" start="2012-07-05T08:25:31.555Z"/>
<chat with="piyush@openfire" start="2012-07-05T12:38:24.098Z"/>
<set xmlns="http://jabber.org/protocol/rsm">
<first index="0">15</first>
<last>25</last>
<count>3</count>
</set>
</list>
</iq>
Now you choose one of starts and send (date and hour must be exacts):
<iq type='get' id='pk1'>
<retrieve xmlns='urn:xmpp:archive'
with='piyush@openfire''
start='2012-07-04T13:16:12.291Z'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>100</max>
</set>
</retrieve>
</iq>
You will receive something like this (depends the max value -> max=30, bodies=30):
<iq type='result' to='vivek@openfire/iphone' id='page1'>
<chat xmlns='urn:xmpp:archive'
with='piyush@openfire'
start='2012-07-04T13:16:12.291Z'
subject='She speaks!'
version='4'>
<from secs='0'><body>Art thou not Romeo, and a Montague?</body></from>
<to secs='11'><body>Neither, fair saint, if either thee dislike.</body></to>
.

<from secs='9'><body>How cam'st thou hither, tell me, and therefore? </body>
</from>
