php-reading xml child node value [duplicate]

Question

Trying to get the node value of ds:X509Certificate in PHP. I am able to navigate till IDPSSODescriptor tag, any pointers on how to access child node values.

<EntityDescriptor>
      <IDPSSODescriptor>
        <ds:Signature >
             <ds:SignedInfo>..</ds:SignedInfo>
             <ds:SignatureValue>..</ds:SignatureValue>
              <ds:KeyInfo>
                 <ds:X509Data>
                   <ds:X509Certificate/>
                 </ds:X509Data>
               </ds:KeyInfo>
         <test>
         <test2>
      </IDPSSODescriptor>
</EntityDescriptor>

php code working so far,

$data = $idp_xml->IDPSSODescriptor->attributes()->ID;

I tried,

$xml = new SimpleXMLElement($idp_xml->IDPSSODescriptor);
$data = (string) $xml->ds:Signature[0]->ds:KeyInfo->ds:X509Data->ds:X509Certificate.

Hi just read your request but xml file does not seemed to be well formed can you supply more details of your xml files — Artful_dodger

Error in your XML, ds is a namespace-prefix, and it is not defined in your snippet, see xmlvalidation.com This is probably the reason why you cannot access it. — michi
