LinearJSON Playlist - What is wrong? (Projekktor Core)

Hi,
I'm after using the playlist feature. I've got a playlist in a XML file:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<playlist>
<vid src="P_CULTURAL TV.f4v" />
<vid src="P_ANIMACION.f4v" />
</playlist>
It would be very useful for me to directly load the playlist from a XML file instead having to generate a JSON file, which would cause huge changes in my software. However, since the code for 'alternate-playlist.xml' shown at the end of the playlist docs is not published, I'm not able to adapt it (obviously I've already tried loading it directly).
Could anyone tell me how must I structure the XML file so the playlist can be loaded from the file? Or, if it's not possible, tell me why this doesn't work?:
[{"0":{"src":"video\/intro.mp4","type":"video\/mp4"},config: {
disablePause: true,
disallowSkip: true
}},{"0":{"src":"video\/intro.mp4","type":"video\/mp4"}}]I've written it as an adaptation of the server.php file.
This is my document.ready:
<script type="text/javascript">
$(document).ready(function() {
projekktor('#player_a', {
volume: 1,
enableFullscreen: true,
continuous: true,
playlist: [
{
0:{src:'playlist.php', type:'text/json'}
}
]
});
});
</script> JSON Playlist - What is wrong?

Okay needed a rest, I just realized the XML file doesn't point to.mp4 files and doesn't have a type attribute. Gonna edit and test.
EDIT: With that edit, it doesn't yet work. However now the 'play' button is displayed, but when pressedit disappears and then reappers (what I guess means that it detects an empty playlist). Here's the XML file now:
<?xml version=1.0" encoding="UTF-8" standalone="no"?>
<playlist>
<vid src="video/intro.mp4" type="video/mp4"/>
<vid src="video/intro.mp4" type="video/mp4"/>
</playlist>

Hi Stoyicker,
thanks for your interesting question. It´s a bit funny that the last XML test I did is a couple of month ago.
As I tried to answer your post I figured out that something is going wrong with the XML stuff and I´m currently investigating that. So: Please stay tuned, you have been heard =).

Thanks sascha. Anyway, since I did the post I've been working on a system for parsing the file and creating a JSON object to be used as playlist target, and I'll post it here when it's finished for public usage.
Here it is:
<!DOCTYPE HTML>
<html>
<head>
<title>Aron Multimedia</title>
<link rel="stylesheet" href="theme/style.css" type="text/css" media="screen" />
<script type="text/javascript" src="libs/jquery.min.js"></script>
<script type="text/javascript" src="libs/projekktor.min.js"></script>
<script type="text/javascript" src="libs/xml2json.js"></script>
</head>
<body>
<video id="player_a" class="projekktor fullscreen pphttp" title="Aron Multimedia" width="640" height="360" preload="auto" autoplay></video>
<script type="text/javascript">
$(document).ready(function() {
player = projekktor('#player_a', {
volume: 1,
enableFullscreen: true,
continuous: true,
disablePause: true,
disallowSkip: true,
playlist: loadJsonPlaylist()
}
});
function loadJsonPlaylist()
{
var xmlDoc;
var jsonPlaylist;
if (window.XMLHttpRequest){
xmlDoc = new window.XMLHttpRequest();
xmlDoc.open("GET", 'playlist.xml', false);
xmlDoc.send("");
jsonPlaylist = xmlToJson(xmlDoc.responseXML);
} else if (ActiveXObject("Microsoft.XMLDOM")){
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
xmlDoc.load('playlist.xml');
jsonPlaylist = xmlToJson(xmlDoc);
}
if(window.XMLHttpRequest || ActiveXObject("Microsoft.XMLDOM")){
var str1 = JSON.stringify(jsonPlaylist);
var str2 = str1.replace(/{(.*?)\[{"0":{"src"/,'[{"0":{"src"');
var cut = str2.substring(0,str2.length-2);
var ret = JSON.parse(cut);
return ret;
}
alert("Error while loading the playlist.xml file.");
return null;
}
function xmlToJson(xml){
var attr, child, attrs = xml.attributes, children = xml.childNodes, key = xml.nodeType, obj = {}, i = -1, o=0;
if (key == 1 && attrs.length){
obj[key = o] = {};
while (attr = attrs.item(++i)){
obj[key][attr.nodeName] = attr.nodeValue;
}
i = -1;
} else if (key == 3){
obj = xml.nodeValue;
}
while (child = children.item(++i)){
key = child.nodeName;
if (obj.hasOwnProperty(key)){
if (obj.toString.call(obj[key])!='[object Array]') {
obj[key] = [obj[key]];
}
obj[key].push(xmlToJson(child));
} else{
obj[key] = xmlToJson(child);
}
}
return obj;
}
