Populating XML Template

[ssimons]

@Aaron,

When you helped me earlier, you included this...

//modify the template to add apropriate values
$xml->merchantAuthentication->addChild('name',$loginId);
$xml->merchantAuthentication->addChild('transactionKey',$transactionKey);
//add the payment information from the information that was posted to this script
$xml->creditCard->addChild('cardNumber',$cardNumber);
$xml->creditCard->addChild('expirationDate',$expirationDate);
$xml->creditCard->addChild('cardCode',$cardCode);

Questions:

1.) Why do you have to use "addChild" to populate the XML template?

Why can't you just type in values like...

<merchantAuthentication>
  <name>$loginID</name>
  <transactionKey>$transactionKey</transactionKey>
</merchantAuthentication>


<creditCard>
  <cardNumber>$cardNumber</cardNumber>
  and so on...
</creditCard>

2.) Where do I find out which "tags" in the XML tree are required?

Is it just what I infer from your earlier explanation?

Thanks,

Sally

Whatever works for you. There's no "right" way, just whichever way ends up sending a valid XML request to our server.
