Building a XML Document with PHP

[hellonoko]

I am trying to build a XML document like this one dynamically:

 

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
    <trackList>
        <track><location>file:///mp3s/song_1.mp3</location></track>
        <track><location>file:///mp3s/song_2.mp3</location></track>
        <track><location>file:///mp3s/song_3.mp3</location></track>
    </trackList>
</playlist>

 

My code so far:

 

<?php
// create doctype
$dom = new DOMDocument("1.0");

// display document in browser as plain text
// for readability purposes
header("Content-Type: text/plain");

// create root element
$root = $dom->createElement("playlist");
$dom->appendChild($root);

// create child element
$item = $dom->createElement("track");
$root->appendChild($item);

// create text node
$item = $dom->createElement("location");
$root->appendChild($item);

// save and display tree
$dom->save("playlist.xml");
?>

 

 

For some reason the createElement location tag is not working.

But I am very new to XML so I am not sure what I am doing.

 

Thanks,
