Payment Gateway

[HolyCow]

Hi

I have setup a payment gateway on my client site and its working fine.

Now the gateway company has changed their setting which i am supposed to implement in my existing gateway.

The new gateway is based on XML Schema Definition language (XSD).

My question is i send the data to the gateway in there specified XML XSD format and they send me a response packet in the same XML XSD format.
I want to know how can i read the response packet. Bocz if i put this response in a variable i cannot read the whole thing.
This gateway also takes care if the customer’s credit card is enrolled for 3D Secure transactions.
So firstly i check if the customer is enrolled for 3D Secure transactions, if yes than redirect to bank website, if not that than redirect to gateway.

I cannot paste the code here as the gateway ppl say its confidential.

<tns:OperationResultSet resultSetName="fthct" oprState="0" oprName="hello">
<tns:ResultSet>
<tns:Result>
<tns:ResultName>helloId</tns:ResultName>
<tns:ResultType>Integer</tns:ResultType>
<tns:ResultValue>41</tns:ResultValue>
</tns:Result>
<tns:Result>
<tns:ResultName>mailId</tns:ResultName>
<tns:ResultType>Long</tns:ResultType>
<tns:ResultValue>10814</tns:ResultValue>
</tns:Result>
<tns:Result>
<tns:ResultName>GatewayTime</tns:ResultName>
<tns:ResultType>Date</tns:ResultType>
<tns:ResultValue>2008-01-01 00:12:25.105</tns:ResultValue>
</tns:Result>

simplexml_load_string() is not supported on my hosting server.
I get error message Call to undefined function: simplexml_load_string()
I am not sure which php version in there on the server.

phpinfo(); will tell you the version

Don't know if any of this will help.

This is something I've used.
PHP: XML Parser - Manual
And a thread with a little demo
xsd xml free class


And this is a nonstandard way I did for something. I knew what was coming in and it was pretty standard all the time so I could manually parse it.

PHP Code:

                $body= htmlspecialchars($body);
                $start=false;
                $start=strpos($body,htmlspecialchars('<Expiration>'));
                  //todo -  update sql
                if ($start!=0)
                   {
                   $date=substr($body,$start+18,10);
                   $da=explode('/',$date);

Php code:

$XML='<tns:Request>
<tns:MsgHeader>
<tns:Gateway></tns:Gateway>
<tns:Credentials>
<tns:LoginId>/tns:LoginId>
<tns:Password></tns:Password>
</tns:Credentials>
</tns:MsgHeader>
<tns:MsgBody>
<tns:Operations>
<tns:Operation>
<tns:ParameterList>
	<tns:ParameterDef parameterName="posId" parameterType="String" parameterValue="41"/>
	<tns:ParameterDef parameterName="transactionId" parameterType="String" parameterValue="$rand"/>
	<tns:ParameterDef parameterName="cardNo" parameterType="String" parameterValue="$cardnumber"/>
	

</tns:ParameterList>
</tns:Operation>
</tns:MsgBody>
</tns:Request>';

This is my request message.
Now if i parse or display this $xml i see all the details leaving details inside parameterdef, why is that?
Do i have to write this parameterdef message in a diff way.

Sorry, I don't understand your question.
