Hello,
I'm trying to figure out how to modify the content of an xml document
using the xml core library, but i don't succeed at appending the newly
created element at the root element. First of all, I have the
following structure of my xml file:
<?xml version="1.0" encoding="UTF-8"?>
<playlists>
<playlist id="1">
<song>
<title>A new song</title>
<filename>A_new_song.mp3</filename>
</song>
<song>
<title>A second song</title>
<filename>A_second_song.mp3</filename>
</song>
</playlist>
<playlist id="2">
<song>
<title>A new song</title>
<filename>A_new_song.mp3</filename>
</song>
</playlist>
</playlists>
And here's how i'm trying to append a new 'playlist' element to the
root element:
$xml = new Xml( 'playlists.xml' );
$new_playlist = $xml->createElement( 'playlist' );
$new_playlist->addAttribute( 'id', 123456 );
$song = $xml->createElement( 'song' );
$title = $xml->createElement( 'title' );
$title->append( $xml->createTextNode('New song title'));
$song->append($title);
$filename = $xml->createElement( 'filename' );
$filename->append( $xml->createTextNode('New song
filename') );
$song->append($filename);
$new_playlist->append( $song );
$xml->append($new_playlist);
Doing like this, the newly created element isn't added to the root
element (playlists), it is added after it. And I can't find a method
in the Xml library that would allow me to append (or in some cases
modify some element) this newly created element to the root element.
Does anyone of you know how can i obtain the result i want? Thanks.
