Używam następującego kodu do konwersji mojego pliku XML do formatu CSV. Niestety, wydaje się, że nie rozpoznaje każdego wpisu w XML i dlatego plik XML jest pusty.

<?php
$filexml='test.xml';
if (file_exists($filexml)) {
  echo 'File Exists';
$xml = simplexml_load_file($filexml);
  $f = fopen('test.csv', 'w');
  foreach ($xml->Item as $item) {
        fputcsv($f, get_object_vars($item),',','"');
  }
  fclose($f);
}
?>

Przykład mojego pliku XML jest poniżej ...
