PHP XML converter response - php

Question

im quite new on XML, i am currently work in PHP and i have a request to other server which normaly and always return the callback with XML
In any case i would not talk about how i get the response, but how to convert the XML reponse.
They are two type of the XML response, we could call it as $response
first :
<BASEELEMENT SCHEMA="RESULT" METHOD="ADD-MBX">
<RETURN_VALUE>4</RETURN_VALUE>
<ERROR_DESCRIPTION>
<![CDATA[Error (7004): Login name already exists. Please use another login name.]]>
</ERROR_DESCRIPTION>
</BASEELEMENT>
and the second one is :
<baseelement schema="TIMEOUT" method="ADD-MBX"></baseelement>
i have searched and i got how to convert the xml reponse to obejct or array, which is
$response = new \SimpleXMLElement($response);
after convert :
object(SimpleXMLElement)#256 (3) {
["#attributes"]=>
array(2) {
["SCHEMA"]=>
string(6) "RESULT"
["METHOD"]=>
string(7) "ADD-MBX"
}
["RETURN_VALUE"]=>
string(1) "4"
["ERROR_DESCRIPTION"]=>
object(SimpleXMLElement)#257 (0) {
}
}
as we can see the ERROR_DESCRIPTION become 0.
So i would like to ask, is there any xml converter else simplexml_load_string() or new \SimpleXMLElement()
i cant use that function because i could not get the ERROR_DESCRIPTION
thank you :)

Loading it as you are with -
$response = new \SimpleXMLElement($response);
You can fetch the value quite simply as...
echo (string)($response->ERROR_DESCRIPTION).PHP_EOL;
If you want the full content (as in an XML version)...
echo $response->ERROR_DESCRIPTION->asXML().PHP_EOL;
Using XPath, you can fetch the values by...
echo (string)$response->xpath("//ERROR_DESCRIPTION")[0].PHP_EOL;
The output you are seeing shows that ERROR_DESCRIPTION is an object of SimpleXMLElement type, not that it isn't loaded.
