Hello! I have a Windows phone, and the playlist extension is .zpl, what I want to do is to make a new playlist and add my own files to it.

This is what it looks like:

<?zpl version="2.0"?>
<smil>
<head>
<guid>{0205EBCA-12CF-458D-BCD5-B1AF6A421940}</guid>
<meta name="autoRefreshInterval" content="5" />
<meta name="autoRefresh" content="FALSE" />
<meta name="creatorId" content="{E9F04267-F937-1EBC-615D-64DD6C3CD144}" />
<meta name="averageRating" content="9" />
<meta name="totalDuration" content="49548 (In seconds)" />
<meta name="itemCount" content="" />
<meta name="generator" content="Zune -- 4.8.2345.0" />
<title>SummerNstuff</title>
</head>
<body>
<seq>
<media src="Searchway" serviceId="{FBDE3507-0100-11DB-89CA-0019B92A3933(what is this?)}" albumTitle="Albumtitle" albumArtist="Artist" trackTitle="Trackname" trackArtist="TrackArtist" duration="In Millisecond" />
</seq>
</body>
</smil>



What should I use? An XML writer or some sort of writer?
And, how should I do it? Thanks in advance!!
