simplexml_import_dom

(PHP 5, PHP 7, PHP 8)

simplexml_import_domConstruit un objet SimpleXMLElement à partir d'un objet DOM

Description

simplexml_import_dom(SimpleXMLElement|DOMNode $node, ?string $class_name = SimpleXMLElement::class): ?SimpleXMLElement

simplexml_import_dom() prend un nœud d'un document DOM et la transforme en nœud SimpleXML. Ce nouvel objet peut alors être utilisé comme un objet natif SimpleXML.

Liste de paramètres

node

Un élément DOM

class_name

Vous pouvez utiliser ce paramètre optionnel afin que simplexml_load_string() retourne un objet de la classe spécifiée. Cette classe doit étendre la classe SimpleXMLElement.

Valeurs de retour

Retourne un objet SimpleXMLElement ou null en cas d'échec.

Exemples

Exemple #1 Import DOM

<?php
$dom
= new DOMDocument;
$dom->loadXML('<books><book><title>blah</title></book></books>');
if (!
$dom) {
echo
'Erreur durant l\'analyse du document';
exit;
}

$s = simplexml_import_dom($dom);

echo
$s->book[0]->title;
?>

L'exemple ci-dessus va afficher :

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 " }

//but
echo $result->p->em;
//prints:
//italic

simplexml_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
