Tei*_*eiv 17 html php dom append prepend
这是我的HTML代码
<html>
<body>
<div>A sample block <div>and child block</div></div>
</body>
</html>
如何使用DOM在不伤害其兄弟姐妹的情况下将文本节点附加到文本节点并将其添加到BODY元素中？
$dom = new DOMdocument();
@$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$body = $xpath->query('//body')->item(0);
像这样
<html>
<body>
Newly prepended text
<div>A sample block <div>and child block</div></div>
Newly appended text
</body>
</html>

您可以使用DOMText(或使用DOMDocument::createTextNode)创建文本节点:
$before = new DOMText('Newly prepended text');
// $before = $dom->createTextNode('Newly prepended text');
$after = new DOMText('Newly appended text');
// $after = $dom->createTextNode('Newly appended text');
现在,追加只是:
$body->appendChild($after);
对于前置,我们可以DOMNode::firstChild用来获得身体的第一个孩子,并且DOMNode::insertBefore:
$body->insertBefore($before, $body->firstChild);
