  Examples
   
Example 1. Saving a DOM tree into a string 
<?php
  $doc = new DOMDocument('1.0'); // we want a nice output $doc->formatOutput = true;
  $root = $doc->createElement('book'); $root = $doc->appendChild($root);
  $title = $doc->createElement('title'); $title = $root->appendChild($title);
  $text = $doc->createTextNode('This is the title'); $text = $title->appendChild($text);
  echo "Saving all the document:\n"; echo $doc->saveXML() . "\n";
  echo "Saving only the title part:\n"; echo $doc->saveXML($title);
  ?>
 |  
 The above example will output: Saving all the document:
<?xml version="1.0"?>
<book>
  <title>This is the title</title>
</book>
Saving only the title part:
<title>This is the title</title>  |
