Dynamically Creating an XML File

[patrickdaly]

Please bear with me. I'm a novice, but I really need to resolve this problem today. Thanks!

I'm creating an XML file via PHP using the following code:

$playlist = array();
    $playlist [] = array(
        'creator' => 'Example Creator',
        'title' => 'Example Title',
        'location' => 'http://example.com/example.flv'
    );
    $playlist [] = array(
        'creator' => 'Example Creator 2',
        'title' => 'Example Title 2',
        'location' => 'http://example.com/example2.flv'
    );
   
    $doc = new DOMDocument("1.0");
    $doc->formatOutput = true;
   
    // create root element
    $p = $doc->createElement( "playlist" );
    $doc->appendChild( $p );
   
    // create child element
    $t = $doc->createElement("tracklist");
    $p->appendChild($t);
       
    foreach( $playlist as $track )
    {
        $b = $doc->createElement( "track" );
       
        $creator = $doc->createElement( "creator" );
        $creator->appendChild(
            $doc->createTextNode( $track['creator'] )
        );
        $b->appendChild( $creator );
       
        $title = $doc->createElement( "title" );
        $title->appendChild(
            $doc->createTextNode( $track['title'] )
        );
        $b->appendChild( $title );
       
        $location = $doc->createElement( "location" );
        $location->appendChild(
            $doc->createTextNode( $track['location'] )
        );
        $b->appendChild( $location );
       
        $t->appendChild( $b );
        $p->appendChild( $t ); 
       
    }
           
    $doc->save("write.xml"); 

Despite my best efforts I can't seem to get the XML to output exactly what I need, which is this:

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
    <trackList>
        <track>
            <creator>Example Creator</creator>
            <title>Example Title</title>
            <location>http://example.com/example.flv</location>
        </track>
 
        <track>
            <creator>Example Creator</creator>
            <title>Example Title</title>
            <location>http://example.com/example2.flv</location>
        </track>
    </trackList>
 
</playlist>

My code isn't writing the encoding (encoding="UTF-8") or the namespace (xmlns="http://xspf.org/ns/0/").

How can I add those attributes to the corresponding nodes?

Thanks for your help!

I've made some progress, but I'm not there yet...

In the previous code, lines 16-18, where I'm creating the root element, I replace it with the following code:

// create root element
$p = $doc->createElementNS( "http://xspf.org/ns/0/","playlist" );
$doc->appendChild( $p ); 

Now I'm getting the namespace to show up. Now I need to add the version attribute to the same line so that the XML output should be:

<playlist version="1" xmlns="http://xspf.org/ns/0/">

I've tried my hand with createAttritbute(), but just can't get it. Remember, I'm a novice!
