Voici mon code si ça vous dit qqch...

<?

if(!isset($_SESSION["langage"])){ $_SESSION['langage'] = "FR"; }

function fct_traduc($str) {
$file = "/translations.xml";
$xml_parser = xml_parser_create();

if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}

$data = fread($fp, filesize($file));
fclose($fp);
xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);

$params = array();
$level = array();
foreach ($vals as $xml_elem) {
if ($xml_elem['type'] == 'open') {
if (array_key_exists('attributes',$xml_elem)) {
list($level[$xml_elem['level']],$extra) = array_values($xml_elem['attributes']);
} else {
$level[$xml_elem['level']] = $xml_elem['tag'];
}
}
if ($xml_elem['type'] == 'complete') {
$start_level = 1;
$php_stmt = '$params';
while($start_level < $xml_elem['level']) {
$php_stmt .= '[$level['.$start_level.']]';
$start_level++;
}
$php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
eval($php_stmt);
}
}
print($params ['TRANSLATIONS'][$str][$_SESSION['langage']]);
}
?>
