Why not just:simplexml_import_dom(dom_import_simplexml($SimpleXmlNode))
(PHP 5, PHP 7, PHP 8)
simplexml_import_dom — Construye un objeto SimpleXMLElement a partir de un objeto XML o HTML
$node, ?string $class_name = SimpleXMLElement::class): ?SimpleXMLElementsimplexml_import_dom() toma un nodo de un documento DOM y lo transforma en nodo SimpleXML. Este nuevo objeto puede entonces ser utilizado como un objeto nativo SimpleXML.
nodeUn elemento DOM
class_nameEste parámetro opcional permite que simplexml_load_string() retorne un objeto de la clase especificada. Esta clase debe extender la clase SimpleXMLElement.
Retorna un objeto SimpleXMLElement o null en caso de fallo.
Lanza una TypeError cuando
un node no-XML o no-HTML es pasado.

Esta función ahora lanza una TypeError en lugar
de una ValueError cuando un
node no-XML o no-HTML es pasado.

Ejemplo #1 Importar un DOMDocument
<?php
$dom = new DOMDocument;
$dom->loadXML('<books><book><title>blah</title></book></books>');
if (!$dom) {
echo 'Error durante el análisis del documento';
exit;
}
$s = simplexml_import_dom($dom);
echo $s->book[0]->title;
?>El ejemplo anterior mostrará :
blah
Ejemplo #2 Importar un Dom\Document
<?php
$dom = Dom\XMLDocument::createFromString('<books><book><title>blah</title></book></books>');
$s = simplexml_import_dom($dom);
echo $s->book[0]->title;
?>El ejemplo anterior mostrará :
blah
Why not just:simplexml_import_dom(dom_import_simplexml($SimpleXmlNode))/*If tags in DOM have text and some part of this text is surrounded by other tag, simple_import_dom object doesn't contain position of child tag, so rendering it back to html/xml can be a problem. Printing such a node is also peculiar. Eg.*///////////////////////$text = "<body><p>Some text before <em>italic </em>and after text.</p></body>";$dom = new DOMDocument;$dom->loadHTML($text);$result = simplexml_import_dom($dom);echo $result->p;////////////////////////Prints ://Some text before and after text.print_r($result->p);//Prints://SimpleXMLElement Object ( [em] => italic )print_r($result->p->em)//does more or less the same://SimpleXMLElement Object ( [0] => italic )var_dump($result->p);//Prints://object(SimpleXMLElement)#8 (1) { ["em"]=> string(7) "italic " }var_dump($result->p->em)//object(SimpleXMLElement)#9 (1) { [0]=> string(7) "italic " }//butecho $result->p->em;//prints://italicsimplexml_import_dom() will accept DOMNodes or other SimpleXMLElements. This has a useful purpose if you are extending the SimpleXMLElement class and would prefer the xpath() method to return your class extension instead of basic SimpleXMLElements. For example:class MySimpleXML extends SimpleXMLElement{ public function xpath($xpath){ $return = array(); $simpleXmls = parent::xpath($xpath); // run SimpleXMLElement xpath, returning an array of SimpleXMLElements foreach($simpleXmls as $xml){ $return[] = simplexml_import_dom($xml,'MySimpleXML'); // copy SimpleXMLElement, returning as MySimpleXML instance } return $return; }}Now I can create an instance of MySimpleXML, run an xpath, and get my results back as an array of MySimpleXML elements instead of the native SimpleXMLElement:$mySimpleXml = new mySimpleXml('<root><node/></root>');$array = $mySimpleXml->xpath('/root/node'); // returns array with a single MySimpleXml object
