I’m having trouble finding some node on WSDL (XML) document with DOMDocument PHP. When I use getElementsByTagName it always return NULL. what I’m about to find is xsd:complexType but when I try different node, let say types, it’s return a object.

This is my WSDL (XML) Document

<definitions xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="urn:routeDx2" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="urn:routeDx2">

   <xsd:element name="terminal" type="xsd:string"/>
   <xsd:element name="merchantNumber" type="xsd:string"/>
   <xsd:element name="transactionType" type="xsd:string"/>
   <xsd:element name="recipientNumber" type="xsd:string"/>
   <xsd:element name="recipientName" type="xsd:string"/>
   <xsd:element name="amount" type="xsd:string"/>
   <xsd:element name="feeAmount" type="xsd:string"/>
   <xsd:element name="verifyingCode" type="xsd:string"/>
   <xsd:element name="traxId" type="xsd:string"/>
   <xsd:element name="timeStamp" type="xsd:string"/>
  </xsd:all>
 </xsd:complexType>
</xsd:schema>
</types>
<definitions>

what I’m about to find is xsd:complexType or if that’s possible, how to find by attribute name that has unique value (verifyingCode or else), how do I accomplish this via PHP and DOMDocument?

    Besides your incorrect closing tag for <definitions> (last line), I don’t see a problem.

    $doc = new DOMDocument();
$doc->loadXML($xml);
$complexTypes = $doc->getElementsByTagName('complexType');
printf('<p>Found %d complexType elements</p>', $complexTypes->length);
foreach ($complexTypes as $complexType) {
    echo $complexType->getAttribute('name'), '<br>';
}

    You’re probably including the xsd namespace in your tag name query. If you read the docs, you will see the argument to getElementsByTagName() specifies

    The local name (without namespace) of the tag to match on
