To edit an online on-demand playlist

In the console tree, click the on-demand publishing point associated with the playlist you want to edit.
In the details pane, click the Source tab.
The path and file name in Location correspond to the playlist that is currently online.
In the playlist tree, expand the playlist, and then expand the smil element to show the elements in the playlist.
Click the element you want to modify.

Use the toolbar above the playlist to perform any of the following steps:

To add a container, click the Add Element arrow, and then do one of the following:

Click this	To do this
Sequence	Add a seq element to the playlist. A seq element is a container for content items, which are played in the order in which they are listed. For more information, see seq element.
Switch	Add a switch element to the playlist. A switch element provides alternate content in case a user is unable to access the intended content. For more information, see switch element.
Exclusive	Add an excl element to the playlist. An excl element is a container for content items that are played only if they are triggered by an event or if a begin attribute is specified and its criteria is met. For more information, see excl element.
priorityClass	Add a priorityClass element to the playlist. A priorityClass element must be an immediate child of an excl element. A priorityClass element enables you to specify what happens when one media element interrupts playback of another. For more information, see priorityClass element.

If you have enabled the WMS Playlist Transform plug-in, you can change the way the playlist is streamed by clicking the following toolbar buttons:
- To have the playlist repeat its content until the publishing point is stopped, click the Loop button.
- To have the playlist stream its content in random order, click the Shuffle button.
