Answer 1

- (void)getAllRegisteredUsers {

    NSError *error = [[NSError alloc] init];
    NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@""
                                                            error:&error];
    XMPPIQ *iq = [XMPPIQ iqWithType:@"get"
                                 to:[XMPPJID jidWithString:@"DOMAIN"]
                          elementID:[xmppStream generateUUID] child:query];
    [xmppStream sendElement:iq];
}

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
    NSXMLElement *queryElement = [iq elementForName: @"query" xmlns: @"http://jabber.org/protocol/disco#items"];

    if (queryElement) {
        NSArray *itemElements = [queryElement elementsForName: @"item"];
        NSMutableArray *mArray = [[NSMutableArray alloc] init];
        for (int i=0; i<[itemElements count]; i++) {

            NSString *jid=[[[itemElements objectAtIndex:i] attributeForName:@"jid"] stringValue];
            [mArray addObject:jid];
        }



    }
