返回值

错误／异常

DOM_HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of one of the passed nodes, or if the node to put in is one of this node's ancestors or this node itself.
DOM_WRONG_DOCUMENT_ERR: Raised if one of the passed nodes was created from a different document than the one that created this node.

更新日志

版本	说明
8.3.0	Calling this method on a node without an owner document now works. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.

示例

示例 #1 DOMDocumentFragment::replaceChildren() example

Replaces the children with new nodes.

<?php
$doc = new DOMDocument;
$doc->loadXML("<container><hello/></container>");
$fragment = $doc->createDocumentFragment();
$fragment->append("hello");

$fragment->replaceWith("beautiful", $doc->createElement("world"));

echo $doc->saveXML($fragment);
?>

以上示例会输出：

beautiful
<world/>
