  {
  $xml = simplexml_load_file('test.xml');
  var_dump($xml);
  }

else
  {
  exit('Error.');
  }
?>

输出：

{
["to"]=> string(4) "George"
["from"]=> string(4) "John"

在PHP语言中我们可以用以下方法取得我们想要的值：

$xmldata = simplexml_load_file("iciba.xml");

header("Content-Type: text/html; charset=UTF-8");
print_r($xmldata); //第一部分www.111com.net

$listcount = count($xmldata->sent);

for($i=0;$i<$listcount;$i++){ //第二部分
 $dictlist = $xmldata->sent[$i];
 echo "
例句：".$dictlist->orig;
 echo "
翻译：".$dictlist->trans;
}
?>“第一部分”将输出：
