If you know the format of the xml file that is needed then you can use php to generate the xml file for you.
PHP Code:
<?php
/*
This is a sample file that reads through a directory, filters the mp3/jpg/flv
files and builds a playlist from it. After looking through this file, you'll
probably 'get the idea' and'll be able to setup your own directory.
*/
// search for mp3 files. set this to '.flv' or '.jpg' for the other scripts
$filter = ".mp3";
// path to the directory you want to scan
$directory = "somedirectory";
// read through the directory and filter files to an array
@$d = dir($directory);
if ($d) {
while($entry=$d->read()) {
$ps = strpos(strtolower($entry), $filter);
if (!($ps === false)) {
$items[] = $entry;
}
}
$d->close();
rsort($items);
}
// third, the playlist is built in an xspf format
// we'll first add an xml header and the opening tags ..
header("content-type:text/xml;charset=utf-8");
echo "<playlist version='1' xmlns='http://xspf.org/ns/0/'>\n";
echo " <title>Sample PHP Generated Playlist</title>\n";
echo " <info>http://www.*******************/</info>\n";
echo " <trackList>\n";
// .. then we loop through the mysql array ..
for($i=0; $i<sizeof($items); $i++) {
echo " <track>\n";
echo " <title>".$filename."</title>\n";
echo " <location>$items[$i]</location>\n";
echo " </track>\n";
}
// .. and last we add the closing tags
echo " </trackList>\n";
echo "</playlist>\n";
/*
That's it! You can feed this playlist to the SWF by setting this as it's 'file'
parameter in your HTML page.
*/
?>
The above code IS the xml file so link to that as the playlist. Just change the directory to match where your mp3 files are stored at.
