simplexml_import_domGet a SimpleXMLElement object from a DOM node.


SimpleXMLElement simplexml_import_dom ( DOMNode $node [, string $class_name = "SimpleXMLElement" ] )

This function takes a node of a DOM document and makes it into a SimpleXML node. This new object can then be used as a native SimpleXML element.



A DOM Element node


You may use this optional parameter so that simplexml_import_dom() will return an object of the specified class. That class should extend the SimpleXMLElement class.

Return Values

Returns a SimpleXMLElement or FALSE on failure.


Example #1 Importing DOM

= new DOMDocument;
if (!
$dom) {
'Error while parsing the document';

$s simplexml_import_dom($dom);


The above example will output:

/*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;
$result = simplexml_import_dom($dom);
echo $result->p;

//Prints :
//Some text before and after text.

//SimpleXMLElement Object ( [em] => italic )

//does more or less the same:
//SimpleXMLElement Object ( [0] => italic )

//object(SimpleXMLElement)#8 (1) { ["em"]=> string(7) "italic " }

//object(SimpleXMLElement)#9 (1) { [0]=> string(7) "italic " }

echo $result->p->em;

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
