XMPP - Retrieve last n messages from chat room

Question

Anyone know if there is a way to query the last n messages in a muc in xmpp (specifically ejabberd) without joining the room.

Thanks.

Answer 1

No, not without modifications to the server software.

If you do actually join, you can specify the amount of history you want with the <history/> element, see Managing Discussion History in XEP 45.
