php-reading xml child node value

本文关键字：子节点 XML 读取 php | 更新日期: 2023-09-27

试图在PHP中获取ds:X509Certificate的节点值。我能够导航到IDPSSODescriptor标签，任何关于如何访问子节点值的指针。

<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代码运行至今，

$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.

$childNode = $idp_xml->IDPSSODescriptor->children();
