Example#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();

?>

上例将输出：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE graph SYSTEM "graph.dtd">
