PHP simplexml_load_string not loading XML

I'm busy with an EPP registration module which returns XML via a stream service. The XML returns fine but I am unable to get PHP simplexml_load_string or new SimpleXMLElement to correctly load the XML so that I can use the data as an object.

I am however able to return the XML back using asXML() so it would appear that the XML is loaded, I am just not able to get access to any of the values within the object. A print_r() of the object also returns an empty object (from what I understand this is correct).

Here is a sample of a login result:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<epp:epp xmlns:epp="urn:ietf:params:xml:ns:epp-1.0">
<epp:result code="1000">
<epp:msg>Access granted</epp:msg>

What I need to get access to is the result code above.

Here is sample PHP I have tried:

// Note that the $var property contains the XML exactly as it is above.
$result = simplexml_load_string($var);
echo $result->response->msg; // Nothing
echo $result->asXML(); // Returns the XML correctly.
$result = new SimpleXMLElement($var);
print_r($result); // Returns an empty object.
echo $result->response->msg; // Nothing
echo $result->toXML(); // Returns the XML correctly.

Any ideas would greatly be appreciated :)


According to the manual simplexml_load_string has the following parameters:

SimpleXMLElement simplexml_load_string ( string $data [, string $class_name = "SimpleXMLElement" [, int $options = 0 [, string $ns = "" [, bool $is_prefix = false ]]]] )

Therefore, I believe that you can load your XML this way :

simplexml_load_string($var, "SimpleXMLElement", 0, "epp", true);

I hope this works for you.
