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
"Retrieving all the document:\n";
echo
$doc->saveXML() . "\n";

echo
"Retrieving only the title part:\n";
echo
$doc->saveXML($title);

?>

The above example will output:

Retrieving all the document:
<?xml version="1.0"?>
<book>
  <title>This is the title</title>
</book>

Retrieving only the title part:
<title>This is the title</title>
