代码如下
George John Reminder Don't forget the meeting! PHP 代码： if (file_exists('test.xml')) { $xml = simplexml_load_file('test.xml'); var_dump($xml); } else { exit('Error.'); } ?> 输出： object(SimpleXMLElement)#1 (4) { ["to"]=> string(4) "George" ["from"]=> string(4) "John" ["heading"]=> string(8) "Reminder" ["body"]=> string(29) "Don't forget the meeting!" }

PHP 代码：

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

  }
?>

输出：

object(SimpleXMLElement)#1 (4)
{
["to"]=> string(4) "George"
["from"]=> string(4) "John"
["heading"]=> string(8) "Reminder"
["body"]=> string(29) "Don't forget the meeting!"

If there is a "iciba.xml" file, its content is as follows:

The code is as follows

Sky Array;Array; The church tower stood against the sky like a finger pointing towards heaven. The church spire looks like a finger pointing to the sky against the sky. A balloon floated across the sky. The balloon floats across the sky. A bolt of lightning lit up the sky. A flash of lightning lit up the sky. A bright moving object appeared in the sky at sunset. At sunset, a moving shiny object appeared in the sky. A bright rainbow arched above. A bright rainbow hangs in the sky. In PHP language we can use the following method to get the value we want: $xmldata = simplexml_load_file("iciba.xml"); header("Content-Type: text/html; charset=UTF-8"); print_r($xmldata); //The first part www.111cn.net $listcount = count($xmldata->sent); for($i=0;$i<$listcount;$i++){ //Part 2 $dictlist = $xmldata->sent[$i]; echo " Example:".$dictlist->orig; echo " Translation:".$dictlist->trans; } ?>"Part 1" will output: SimpleXMLElement Object ( [@attributes] => Array (                                                                           [num] => 219                                                                                                                   [id] => 219                                                                                                                     [name] => 219 ) [key] => sky [pos] => SimpleXMLElement Object ( ) [acceptation] => Array; Array; [sent] => Array (                                                                                                                   [0] => SimpleXMLElement Object (                                                                                                                  [orig] => The church tower stood against the sky like a finger pointing towards heaven. [Trans] = & GT; The pagoda of the church is like a finger at the sky against the sky. )            [1] => SimpleXMLElement Object ( [Orig] = & GT; a Balloon Floated across the sky.

Example: The church tower stood against the sky like a finger pointing towards heaven.

Translation: The church steeple looks like a finger pointing to the sky against the sky.

Example: A balloon floated across the sky.

Translation: Balloons float across the sky.

Example: A bolt of lightning lit up the sky.

The code is as follows
