$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);

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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>
