Beispiel #1 Creating a document with an attached DTD
<?php
// Creates an instance of the DOMImplementation class
$imp = new DOMImplementation;
// Creates a DOMDocumentType instance
$dtd = $imp->createDocumentType('graph', '', 'graph.dtd');
// Creates a DOMDocument instance
$dom = $imp->createDocument("", "", $dtd);
// Set other properties
$dom->encoding = 'UTF-8';
$dom->standalone = false;
// Create an empty element
$element = $dom->createElement('graph');
// Append the element
$dom->appendChild($element);
// Retrieve and print the document
echo $dom->saveXML();
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
<?xml version="1.0" encoding="UTF-8" standalone="no"?> <!DOCTYPE graph SYSTEM "graph.dtd"> <graph/>
