public final class ASXFilter

extends XMLPlaylistFilter

ASXFilter -- transforms ASX playlist to ptarmigan playlist

Example source:

   <ASX version="3.0">
       <ABSTRACT>This is a sample asx file used as playlist</ABSTRACT>
       <TITLE>Windows Media Playlist Demo</TITLE>
       <AUTHOR>Reed Esau</AUTHOR>
       <COPYRIGHT>2002 Reed Esau</COPYRIGHT>
       <ENTRY>
               <REF href="File1.asf" />
               <ABSTRACT>Link to a local file on the same folder</ABSTRACT>
       </ENTRY>
       <ENTRY>
               <REF href="mms://media.phm.lu/File2.asf" />
               <ABSTRACT>a file streamed from a media server on the network</ABSTRACT>
       </ENTRY>
       <ENTRY>
               <REF href="File3.mp3" />
               <ABSTRACT>ASX can support any file type supported by WMP</ABSTRACT>
       </ENTRY>
       <ENTRY>
               <REF href="File4.avi" />
               <ABSTRACT>you can even mix audio files and video files in the same ASX</ABSTRACT>
       </ENTRY>
   </ASX>
 

The equivalent XSLT would appear thus:

   <xsl:template match="/ASX">
       <pl:playlist>
           <pl:properties>
               <pl:title><xsl:value-of select='TITLE'/></pl:title>
               <pl:author><xsl:value-of select='AUTHOR'/></pl:author>
               <pl:copyright><xsl:value-of select='COPYRIGHT'/></pl:copyright>
               <pl:summary><xsl:value-of select='ABSTRACT'/></pl:summary>
               <pl:entry-count><xsl:value-of select='count(ENTRY)'/></pl:entry-count>
           </pl:properties>
           <xsl:if test="$include_entries = 'true'">
               <xsl:apply-templates select="ENTRY"/>
           </xsl:if>
       </pl:playlist>
   </xsl:template>

   <xsl:template match="ENTRY">
       <pl:entry>
           <pl:path><xsl:value-of select='REF/@href'/></pl:path>
           <pl:title><xsl:value-of select='ABSTRACT'/></pl:title>
       </pl:entry>
   </xsl:template>
 

TODO: recursively scan all playlists found.
