DOMDocumentFragment::appendXML()

(PHP 5 >= 5.1.0, PHP 7)

Append raw XML data

说明

publicDOMDocumentFragment::appendXML(string $data): bool

Appends raw XML data to a DOMDocumentFragment.

This method is not part of the DOM standard. It was created as a simpler approach for appending an XML DocumentFragment in a DOMDocument.

If you want to stick to the standards, you will have to create a temporary DOMDocument with a dummy root and then loop through the child nodes of the root of your XML data to append them.

参数

$data

XML to append.

返回值

成功时返回TRUE，或者在失败时返回FALSE。

范例

Example #1 Appending XML data to your document

<?php
$doc = new DOMDocument();
$doc->loadXML("<root/>");
$f = $doc->createDocumentFragment();
$f->appendXML("<foo>text</foo><bar>text2</bar>");
$doc->documentElement->appendChild($f);
echo $doc->saveXML(); 
?>

以上例程会输出：

<?xml version="1.0"?>
<root><foo>text</foo><bar>text2</bar></root>

Here is (maybe) a better example:
/** 
* Helper function for replacing $node (DOMNode) 
* with an XML code (string) 
* 
* @var DOMNode $node 
* @var string $xml 
*/ 
public function replaceNodeXML(&$node,$xml) { 
 $f = $this->dom->createDocumentFragment(); 
 $f->appendXML($xml); 
 $node->parentNode->replaceChild($f,$node); 
}
