XMPPFramework - XEP-0048: Bookmark Storage
In my app, I have implemented creating XMPPRoom and inviting users. Now, I am searching for a way to store these groups (my created or the groups i have been invited to) so that i can easily retrieve it back in my app when I want. I came across bookmark XEP-0048 however, I can't find any example of using this online. Has anyone used this before? Can you please share some examples?

According to XEP-0048: Bookmarks, to upload bookmarks to server, you have to send a iq request like this:
-
JC http://jabber.org/protocol/pubsub#publish-options true whitelist In Objective-C using NSXMLElement class, above XML can be written as this:
NSXMLElement *pubsub = [[NSXMLElement alloc] initWithName:@"pubsub" xmlns:@"http://jabber.org/protocol/pubsub"]; NSXMLElement *publish = [[NSXMLElement alloc] initWithName:@"publish"]; [publish addAttributeWithName:@"node" stringValue:@"storage:bookmarks"]; NSXMLElement *item = [[NSXMLElement alloc] initWithName:@"item"]; [item addAttributeWithName:@"id" stringValue:@"current"]; NSXMLElement *storage = [[NSXMLElement alloc] initWithName:@"storage" xmlns:@"storage:bookmarks"]; NSXMLElement *conference = [[NSXMLElement alloc] initWithName:@"conference"]; [conference addAttributeWithName:@"name" stringValue:@"The Play's the Thing"]; [conference addAttributeWithName:@"autojoin" stringValue:@"true"]; [conference addAttributeWithName:@"jid" stringValue:@"theplay@conference.shakespeare.lit"]; NSXMLElement *nick = [[NSXMLElement alloc] initWithName:@"nick" stringValue:@"JC"]; [conference addChild:nick]; [storage addChild:conference]; [item addChild:storage]; [publish addChild:item]; NSXMLElement *publish_options = [[NSXMLElement alloc] initWithName:@"publish-options"]; NSXMLElement *x = [[NSXMLElement alloc] initWithName:@"x" xmlns:@"jabber:x:data"]; [x addAttributeWithName:@"type" stringValue:@"submit"]; NSXMLElement *field1 = [[NSXMLElement alloc] initWithName:@"field"]; [field1 addAttributeWithName:@"var" stringValue:@"FORM_TYPE"]; [field1 addAttributeWithName:@"type" stringValue:@"hidden"]; NSXMLElement *value1 = [[NSXMLElement alloc] initWithName:@"value" stringValue:@"http://jabber.org/protocol/pubsub#publish-options"]; [field1 addChild:value1]; [x addChild:field1]; NSXMLElement *field2 = [[NSXMLElement alloc] initWithName:@"field"]; [field2 addAttributeWithName:@"var" stringValue:@"pubsub#persist_items"]; NSXMLElement *value2 = [[NSXMLElement alloc] initWithName:@"value" stringValue:@"whitelist"]; [field2 addChild:value2]; [x addChild:field2]; [publish_options addChild:x]; [pubsub addChild:publish]; [pubsub addChild:publish_options]; XMPPIQ *iq = [[XMPPIQ alloc] initWithType:@"set" child:pubsub]; [iq addAttributeWithName:@"from" stringValue:@"juliet@capulet.lit/balcony"]; [iq addAttributeWithName:@"id" stringValue:@"pip1"]; Of course it could be written with only one NSXMLElement, something like
NSXMLElement *iq = [NSXMLElement alloc] initWithName:@"iq" stringValue:[NSString stringWithFormat:@"all xml code from first paragraph with %@ to add your dynamic data...", data1, data2, ...]; [iq addAttributeWithName:@"from" stringValue:@"juliet@capulet.lit/balcony"]; [iq addAttributeWithName:@"id" stringValue:@"pip1"]; After iq has been created it is time to send it to the server like
[xmppStream sendElement:iq]; and this is the way bookmarks are sent to server. You listen for server response in in XMPPStream delegate - (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq and server response should be something like this:
or in objective-c code:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq { if([iq isResultIQ]) { if([[iq attributeStringValueForName:@"id"] isEqualToString:@"pip1"]) { NSLog(@"Bookmarks with id %@ succesfully uploaded", [iq attributeStringValueForName:@"id"]); } } } Now, based on example from above create objective-c code for xml with which clinet is requesting bookmarks from server (XEP-0048: Bookmarks 3.3 Retrieving Data):
objective-c code:
NSXMLElement *pubsub = [[NSXMLElement alloc] initWithName:@"pubsub" xmlns:@"http://jabber.org/protocol/pubsub"]; NSXMLElement *items = [[NSXMLElement alloc] initWithName:@"items"]; [items addAttributeWithName:@"node" stringValue:@"storage:bookmarks"]; [pubsub addChild:items]; XMPPIQ *iq = [[XMPPIQ alloc] initWithType:@"get" child:pubsub]; [iq addAttributeWithName:@"from" stringValue:@"juliet@capulet.lit/balcony"]; [iq addAttributeWithName:@"id" stringValue:@"retrive1"]; send it to the server like before:
[xmppStream sendElement:iq]; and listen for server response like before:
-
JC or objective-c code:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq { if([iq isResultIQ]) { if([[iq attributeStringValueForName:@"id"] isEqualToString:@"retrive1"]) { NSXMLElement *pubsub = [iq elementForName:@"pubsub"]; NSArray *items = [pubsub elementsForName:@"items"]; NSLog(@"Bookmarks for id %@ are: %@", [iq attributeStringValueForName:@"id"], items); } } } Answer by PETER for XMPPFramework - XEP-0048: Bookmark Storage
Whenever you create a group or accepts a chatroom invitation, store the group to local database with the necessary information. Delete it from db while exiting the group.
Answer by TMD for XMPPFramework - XEP-0048: Bookmark Storage
You very easy to doing this way. Please try this. you can add to bookmark in server using this method.
-(void)bookMark :(NSString *)roomName{ XMPPIQ *iq = [[XMPPIQ alloc]init]; [iq addAttributeWithName:@"type" stringValue:@"set"]; NSString *from = [NSString stringWithFormat:@"%@/ResouseName",[[AppDelegate instance] xmppStream].myJID.bare]; [iq addAttributeWithName:@"from" stringValue: from]; NSXMLElement *query =[NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:private"]; NSXMLElement *storage = [NSXMLElement elementWithName:@"storage" xmlns:@"storage:bookmarks"]; NSXMLElement *conference_s = [NSXMLElement elementWithName:@"conference"]; [conference_s addAttributeWithName:@"autojoin" stringValue:@"true"]; [conference_s addAttributeWithName:@"jid" stringValue:roomName]; [storage addChild:conference_s]; [query addChild:storage]; [iq addChild:query]; NSLog(@"print eml log %@:",iq); [xmppStream sendElement:iq]; } Answer by TMD for XMPPFramework - XEP-0048: Bookmark Storage
Get User groups from jabber server.
XMPPIQ *iq = [[XMPPIQ alloc]init]; [iq addAttributeWithName:@"type" stringValue:@"get"]; NSString *from = [NSString stringWithFormat:@"%@/ResouseName",[[AppDelegate instance] xmppStream].myJID.bare]; [iq addAttributeWithName:@"from" stringValue:from]; NSXMLElement *query =[NSXMLElement elementWithName:@"query" xmlns:@"jabber:iq:private"]; NSXMLElement *storage = [NSXMLElement elementWithName:@"storage" xmlns:@"storage:bookmarks"]; [query addChild:storage]; [iq addChild:query]; [xmppStream sendElement:iq]; Answer by TMD for XMPPFramework - XEP-0048: Bookmark Storage
Finally you can get your group list.
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq { NSXMLElement *pubsub = [iq elementForName:@"query"]; NSXMLElement *storage = [pubsub elementForName:@"storage"]; NSArray *conferenceName = [storage elementsForName:@"conference"]; for (NSXMLElement *conference in conferenceName) { NSString *jid = [[conference attributeForName:@"jid"]stringValue]; NSLog(@"print conference jid=====%@",jid); } NSLog(@"Bookmarks for id are: %@", conferenceName); Fatal error: Call to a member function getElementsByTagName() on a non-object in D:\XAMPP INSTALLASTION\xampp\htdocs\endunpratama9i\www-stackoverflow-info-proses.php on line 72
