SimpleXMLElement->xpath
Something that surprised me, any changes made to the SimpleXML object obtained from the imported DOMDocument also change the original DOMDocument.
e.g.
<?php
$string = '<root><foo>abc</foo></root>';
$domxml = DOMDocument::loadXML($string);
$simplexml = simplexml_import_dom($domxml);
$simplexml->foo = "xyz";
$simplexml->bar = "123";
echo $domxml->saveXML();
?>
Outputs:
--START--
<?xml version="1.0"?>
<root><foo>xyz</foo><bar>123</bar></root>
simplexml_import_dom
(PHP 5)
simplexml_import_dom — Obtiene un objeto SimpleXMLElement a partir de un nodo DOM.
Descripción
Esta función toma un nodo de un documento DOM y crea un nodo SimpleXML a partir de él. Este nuevo objeto puede usarse como un elemento SimpleXML nativo. Si ocurre algún error se devolverá FALSE.
Example #1 Importar DOM
<?php
$dom = new domDocument;
$dom->loadXML('<books><book><title>blah</title></book></books>');
if (!$dom) {
echo 'Error al parsear el documento';
exit;
}
$s = simplexml_import_dom($dom);
echo $s->book[0]->title; // blah
?>

Please note that a valid SimpleXMLElement is typecasted to false.
<?php
$string = '<root><foo>abc</foo></root>';
$xml = DOMDocument::loadXML($string);
$xml = simplexml_import_dom($xml);
echo 'simplexml_import_dom';
var_dump($xml);
var_dump((bool)$xml);
$xml = simplexml_load_string('<root><foo>abc</foo></root>');
echo 'simplexml_load_string';
var_dump($xml);
var_dump((bool)$xml);
$xml = simplexml_load_file('test.xml');
echo 'simplexml_load_file';
var_dump($xml);
var_dump((bool)$xml);
?>
Outputs:
--START--
simplexml_import_dom
object(SimpleXMLElement)[2]
public 'foo' => 'abc'
false
simplexml_load_string
object(SimpleXMLElement)[1]
public 'foo' => 'abc'
false
simplexml_load_file
object(SimpleXMLElement)[2]
public 'foo' => 'abc'
