{{website|XPSF|http://www.xspf.org/}}
'''XSPF''', pronounced "spiff", is a [[playlist]] in [[XML]] format, which is supported by [[Xiph]]. It is a free and open format so can be easily, freely used for sharing playlists.

== Sample ==
A very simple document looks like this:
 <?xml version="1.0" encoding="UTF-8"?>
  <playlist version="1" xmlns="http://xspf.org/ns/0/">
     <trackList>
         <track><location>file:///mp3s/song_1.mp3</location></track>
         <track><location>file:///mp3s/song_2.mp3</location></track>
         <track><location>file:///mp3s/song_3.mp3</location></track>
     </trackList>
  </playlist>

== VLC Extensions ==
XSPF supports extensions to allow applications to add special data. These extensions can appear in the following entries:
* playlist
* track

The extension format is defined in the namespace <code>xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/"</code>:
 <playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/">
  ...
  <extension application="http://www.videolan.org/vlc/playlist/0">
   ...
  </extension>
 </playlist>

Currently, extensions support the following elements:
* vlc:node
* vlc:item
* vlc:id
* vlc:option

The extensions vlc:node and vlc:item are used to specify how to display the playlist tree, which is not supported by standard XSPF.

=== vlc:node ===
This element will be displayed as a node in the playlist. It appears as an extension of the '''playlist''' block (under playlist/extension). Only its name can be specified:
 <vlc:node title="Node title">
  [list of vlc:item or vlc:node]
 </vlc:node>

=== vlc:item ===
This element represents a playlist item (not a node). It appears as an extension of the '''playlist''' block (under playlist/extension). It contains only a track id (see below, vlc:id):
 <vlc:item tid="42" />

=== vlc:id ===
This element specifies a track's id. It appears as an extension of the '''track''' block (under playlist/trackList/track/extension).
 <vlc:id>42</vlc:id>
The value of the id corresponds to the value of the attribute tid of vlc:item.

=== vlc:option ===
This element allows you to add options to the input item. It appears as an extension of the '''track''' block (under playlist/trackList/track/extension).
 <vlc:option>option-name</vlc:option>
Or, if the option has a value:
 <vlc:option>option-name=option-value</vlc:option>

=== Example of XSPF with VLC extensions ===
Let's summarize these as an example:
 <?xml version="1.0" encoding="UTF-8"?>
 <playlist version="1" xmlns="http://xspf.org/ns/0/" xmlns:vlc="http://www.videolan.org/vlc/playlist/ns/0/">
     <title>Playlist</title>
     <location>D:/media/example.xspf</location>
     <trackList>
         <track>
             <title>Track 1</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>0</vlc:id>
             </extension>
         </track>
         <track>
             <title>Track 2</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>1</vlc:id>
             </extension>
         </track>
         <track>
             <title>Track 3</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>2</vlc:id>
             </extension>
         </track>
         <track>
             <title>Track 4</title>
             ...
             <extension application="http://www.videolan.org/vlc/playlist/0">
                 <vlc:id>3</vlc:id>
                 <vlc:option>my-option=42</vlc:option>
             </extension>
         </track>
     </trackList>
     <extension application="http://www.videolan.org/vlc/playlist/0">
         <vlc:node title="Node 1">
             <vlc:item tid="0" />
             <vlc:item tid="1" />
             <vlc:node title="Node 2">
                 <vlc:item tid="2" />
                 <vlc:item tid="3" />
             </vlc:node>
         </vlc:node>
     </extension>
 </playlist>

This playlist example will be displayed as:
 Playlist
 `- Node 1
    |- Track 1
    |- Track 2
    `- Node 2
       |- Track 3
       `- Track 4

The input for ''Track 4'' will be created with the option ''my-option'' set to 42.

There are many advantages to using XML as the format.
