Talk:XMBML Coding

Tips and tools

• An usefull trick to help documenting xml strings is to drag-and-drop all PS3 .xml files (from path dev_flash/vsh/resource/explore/xmb/) to notepad++. Then use the search function in notepad++ (ctrl+F) to search for a text string and click in "find all in all opened documents"

Suggestions, etc

• The <View id>'s "root", "root_for_dex", "root_for_BDU", "tool_root", "shop_root", "shop_guest_root", "shop_staff_root", "root_arcade" refered as XMB enviroments is not an accurate definition, is an invented name, i have no idea if there is a more accurate definition in other parts of the firmware, documentation, whatever... if someone has a better idea please update the frontpage and erase this section here in talkpage --Sandungas (talk) 23:42, 23 January 2014 (EST)

• The View ID "root" usually is refered as the identifyer of a group of items that will be loaded by retail XMB, but not always, e.g:
  • Retail XMB network column is built loading the "root" items of the file "category_network.xml" (there are no debug items in this file)
  • Debug XMB network column is built loading the "root" items of the file "category_network_tool2.xml" (there are no retail items in this file)

Automated XMB/XML navigation

Is posible to automatize the navigation of the cursor in XMB by sending commands from a plugin.sprx (and maybe other alternative ways)

This "navigation sequences" can be seen inside some plugins.sprx, and seems to be direct references to the structure of the XML files, is not clear where is the complete list of functions so by now this is only a messy list to take some notes

• focus_category can be used with game, photo, video, etc... any XMB column
• wait (e.g: 1000, 2000)
• focus_segment_index seg_newvmc 0 (loads a segment from a .xml, then sets the value 0)
• focus_segment_index seg_sdpsp 0.scroll_list -1 1000 (this is a complex sequence of actions)
• open_list
• yield

XML structure levels

The table is ok but it has a problem, is not posible to represent where is located <String> (chldren of <Pair>)... so this probably needs to be replaced by something better

XML tag levels					Common tags
lv1	lv2	lv3	lv4	lv5	version	id	class	key	attr	src	include
XMBML					Yes	No	No	No	No	No	No
	View				No	Yes	No	No	No	No	No
		Attributes	Table		No	No	No	Yes	No	No	Opt
				Pair	No	No	No	Yes	No	No	No
		Items	Query		No	No	Yes	Yes	Opt	Opt	No
			Item		No	No	Yes	Yes	Opt	Opt	No

• This is the last unknown, seems to be used to specify a class by its ID (used as replacement of type:), is unknown if it can be used with Query classes, Item classes, or with both

 <Query class="clsid:unknown_id"/>
 <Item class="clsid:unknown_id"/>

#include Table

In old firmwares there seems to be a way to include attribute tables inside other attribute tables, it works in the same way like in some coding languages, the included stuff needs to be loaded before the tag that includes it, and the names used are the same than the table keys, as example, using the minimalistic example of front page:

	<View id="example">
		<Attributes>
			<Table key="PS3_cover_size">
				<Pair key="icon_fixed_width"><String>170</String></Pair>
				<Pair key="icon_fixed_height"><String>200</String></Pair>
 			</Table>
			<Table key="game_001" include="PS3_cover_size">
				<Pair key="icon"><String>...game_001_cover.jpg</String></Pair>
 			</Table>
			<Table key="game_002" include="PS3_cover_size">
				<Pair key="icon"><String>...game_002_cover.jpg</String></Pair>
 			</Table>
			<Table key="game_003" include="PS3_cover_size">
				<Pair key="icon"><String>...game_003_cover.jpg</String></Pair>
 			</Table>
		</Attributes>
		<Items>
			<Item key="game_001" attr="game_001"/>
			<Item key="game_001" attr="game_002"/>
			<Item key="game_001" attr="game_003"/>
		</Items>
	</View>

In the example the attribute tables named "game_xxx" are going to load the contents of the table named "PS3_cover_size", this can be used when there are several items that uses the same attributes, is posible to create some common groups of attributes that defines a group (for restrictions or shared features), and then create more items or querys that loads an small attribute table specific for the icon + additionally the included attributes common for this kind of item. This is specially useful to make custom .xml files much smaller by removing duplicated lines (like webman)

Music lists

In category_music.xml firmware 0.83

	<View id="root">
		<Attributes>
			<Table key="attr_hdd_contents">
				<Pair key="view0"><String>xcb://localhost/query?sort=+Music:MusicServed.playerForSort+Music:MusicServed.listTitleForSort+Music:MusicServed.trackNumber&cond=Aa+Music:Music.codec</String></Pair>
				<Pair key="view1"><String>xcb://localhost/query?sort=+Music:MusicServed.listTitleForSort&cond=Aa+Music:MusicServed.listTitleForSort_lst</String></Pair>
				<Pair key="view2"><String>xcb://localhost/query?sort=+Music:MusicServed.playerForSort&cond=Aa+Music:MusicServed.playerForSort_lst</String></Pair>
				<Pair key="view3"><String>xcb://localhost/query?sort=+Music:MusicServed.genre&cond=Aa+Music:MusicServed.genre_lst</String></Pair>
			</Table>
		</Attributes>

		<Items>
			<Query 
				class="type:x-xmb/folder-pixmap" 
				key="seg_hdd_contents" 
				attr="attr_hdd_contents"
				src="xcb://localhost/query?sort=+Music:MusicServed.playerForSort+Music:MusicServed.listTitleForSort+Music:MusicServed.trackNumber&cond=Aa+Music:Music.codec"
				/>
		</Items>
	</View>

• Non-standard/unknown:
  • Attribute keys: view0, view1, view2, view3
  • XMB database field names terminated with _lst: (listTitleForSort_lst, playerForSort_lst, genre_lst)
