说明

public DOMElement::replaceWith(DOMNode|string ...$nodes): void

Replaces the element with new nodes.

参数

nodes: The replacement nodes. Strings are automatically converted to text nodes.

返回值

没有返回值。

错误／异常

DOM_HIERARCHY_REQUEST_ERR: Raised if the parent 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 a parent is now a no-op to align the behaviour with the DOM specification. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.

示例

示例 #1 DOMElement::replaceWith() example

Replaces the element with new nodes.

<?php
$doc = new DOMDocument;
$doc->loadXML("<container><hello/></container>");
$cdata = $doc->documentElement->firstChild;

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

echo $doc->saveXML();
?>

以上示例会输出：

<?xml version="1.0"?>
<container>beautiful<world/></container>
