范例

Example#1 Creating a new element and inserting it as root

  <?php 
 
$dom   = new   DOMDocument  (  '1.0'  ,   'iso-8859-1'  ); 
 
  $element   =   $dom  ->  createElement  (  'test'  ,   'This is the root element!'  ); 
 
  // We insert the new element as root (child of the document) 
  $dom  ->  appendChild  (  $element  ); 
 
echo   $dom  ->  saveXML  (); 
  ?>

上例将输出：

<?xml version="1.0" encoding="iso-8859-1"?>
<test>This is the root element!</test>
