示例 #1 DOMParentNode::replaceChildren() example
<?php
$dom = new DOMDocument();
$dom->loadHTML('<!DOCTYPE HTML><html><p>hi</p> test <p>hi2</p></html>');
$dom->documentElement->replaceChildren('foo', $dom->createElement('p'), 'bar');
echo $dom->saveXML();
?>
以上示例会输出:
<?xml version="1.0" standalone="yes"?> <!DOCTYPE HTML> <html>foo<p/>bar</html>
