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>
