PHP中文网词条详解范例

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);
?>

以上例程会输出:

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>
