范例
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);

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>
