#013331: Renaming a node when using ezcTreeXml corrupts the XML

This might be a misusage from myself, but the way i found to rename a node results in a corrupted XML Format. Find below the code snippet used to reproduce this.

The <etd:data>Non-Metals renamed</etd:data> tag of the renamed node was moved after its children <node> elements, which seems not to be valid.

Run the following piece of code, and then inspect the output XML. You will additionnally get the exception reported below the code snippet.

$store = new ezcTreeXmlInternalDataStore();
// $tree = ezcTreeMemoryXml::create( '', $store );
$tree = ezcTreeXml::create( '/tmp/test.xml', $store );
$tree->autoId = true;

$rootNode = $tree->createNode( null, 'Elements' );
$tree->setRootNode( $rootNode );

$nonMetal = $tree->createNode( 'NonMetals', 'Non-Metals' );
$rootNode->addChild( $nonMetal );
$nobleGasses = $tree->createNode( null, 'Noble Gasses' );
$rootNode->addChild( $nobleGasses );

$nonMetal->addChild( $tree->createNode( null, 'Hydrogen' ) );
$nonMetal->addChild( $tree->createNode( null, 'Carbon' ) );
$tree->saveFile();
echo '<pre>';
echo file_get_contents( '/tmp/test.xml' );
echo '</pre>';

echo '<hr />'; 

$NonMetals = $tree->fetchNodeById( 'NonMetals' );
$NonMetals->dataFetched = true;
$NonMetals->data = "Non-Metals renamed";
$tree->saveFile();

$NonMetals = $tree->fetchNodeById( 'NonMetals' );

echo '<pre>';
echo file_get_contents( '/tmp/test.xml' );
echo '</pre>';

$tree = new ezcTreeXml( '/tmp/test.xml', $store );
