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:
