我想将XML树添加到另一个XML中,我尝试使用以下不起作用的代码:
<?php
$str1 = '<parent>
<name>mrs smith</name>
</parent>';
$xml1 = simplexml_load_string($str1);
print_r($xml1);
$str2 = '<tag>
<child>child1</child>
<age>3</age>
</tag>';
$xml2 = simplexml_load_string($str2);
print_r($xml2);
$xml1->addChild($xml2);
print_r($xml1);
?>
期望输出XML:
<parent>
<name>mrs smith</name>
<tag>
<child>child1</child>
<age>3</age>
</tag>
</parent>
请帮助我。

$tagDoc = new DOMDocument;
$tagDoc->loadXML($str2);
$tagNode = $tagDoc->getElementsByTagName("tag")->item(0);
//echo $tagDoc->saveXML();
$newdoc = new DOMDocument;
$newdoc->loadXML($str1);
$node = $newdoc->importNode($tagNode, true);
$newdoc->documentElement->appendChild($node);
echo $newdoc->saveXML();die;
