simpelXMLElement attribute namespaces - php

Question

I looking into this problem for a few days now and need some help with it.
I want to access the namespaced attributes for the 'inhoud' element.
In this case, for example, I want the attribute value from the contentType attribute. So I want to grab the 'text/plain' value.
<inhoud p10:contentType="text/plain" p6:bestandsnaam="hallo 2.txt" xmlns:p10="http://www.w3.org/2005/05/xmlmime">aGFsbG8gZGFhciB4DQoNCg0K</inhoud>
It's prefixed with the p10 namespace.
Below the XML:
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<updateZaakdocument_Di02 xmlns="http://www.egem.nl/StUF/sector/zkn/0310">
<edcLk02 p6:entiteittype="EDC" p6:functie="update" xmlns:p6="http://www.egem.nl/StUF/StUF0301">
<parameters>
<p6:mutatiesoort>W</p6:mutatiesoort>
</parameters>
<object p6:entiteittype="EDC" p6:sleutelVerzendend="934087" p6:verwerkingssoort="W">
<inhoud p10:contentType="text/plain" p6:bestandsnaam="hallo 2.txt" xmlns:p10="http://www.w3.org/2005/05/xmlmime">aGFsbG8gZGFhciB4DQoNCg0K</inhoud>
</object>
</edcLk02>
</updateZaakdocument_Di02>
</s:Body>
</s:Envelope>
I have tried this:
<?php
$sxe = new SimpleXMLElement($xml);
$namespaces = $sxe->getNamespaces(true);
$body = $sxe->xpath('//s:Body')[0];
$inhoud = $body->updateZaakdocument_Di02->edcLk02->object->inhoud->children($namespaces["p10"]);
print_r($inhoud);
the result is:
SimpleXMLElement Object
(
[#attributes] => Array
(
[contentType] => text/plain
)
)
I tried from there:
echo (string) $inhoud >attributes($namespaces["p10"], true)->contentType;
But never get the value out of it.

Can someone point me to the right solution here?
Thanks in advance (-:

Answer 1

I think when your fetching the $inhoud value, your fetching the children in the p10 namespace. What instead you need to do is fetch the attributes in the p10 namespace...
$inhoud = $body->updateZaakdocument_Di02->edcLk02->object->inhoud;
print_r($inhoud);
echo "contentType=".(string)$inhoud->attributes($namespaces["p10"])->contentType;
This outputs...
SimpleXMLElement Object
(
[0] => aGFsbG8gZGFhciB4DQoNCg0K
)
contentType=text/plain
Also when using the various methods using namespaces, the second parameter is to flag that your using the prefix. When using $namespaces["p10"] this is the URI and so you should leave the second parameter out.
