XSPF Playlist

I've made this XSPF template, because I haven't found a proper other template in the forum.

$filename(%_workingpath%%_workingdir%.xspf,utf-8)<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
	<title>$replace(%_workingdir%,&,&amp;)</title>
	<trackList>
	$loop(%fieldname%)	<track>
			<title>$replace(%title%,&,&amp;)</title>
			<duration>%_length_seconds%000</duration>
			<trackNum>%track%</trackNum>
			<album>$replace(%album%,&,&amp;)</album>
			<creator>$replace(%artist%,&,&amp;)</creator>
			<annotation>%comment%</annotation>
			<location>$replace(%_filename_rel%,&,&amp;)</location>
		</track>
	$loopend()</trackList>
</playlist>

I only need somthing like %_length_miliseconds% to complete this template.
