Integration and Testing

[1MSC2020]

I am using the transactionCaller.php script in Laravel. It is giving me an error "

local.ERROR: simplexml_load_string(): namespace warning : xmlns: URI AnetApi/xml/v1/schema/AnetApiSchema.xsd is not absolute" 

I was getting the same error on the creation of the XML. If found an answer that to make the namespace absolute I had to add HTTP:// before it. That worked.

$transRequestXmlStr=<<<XML
        <?xml version="1.0" encoding="UTF-8"?>
        <createTransactionRequest xmlns="http://AnetApi/xml/v1/schema/AnetApiSchema.xsd">

However, when I receive the XML back it has the namespace without the HTTP:// so I get the error. It is not a warning in Laravel it is a 500 error.

Hello,

Authorize.Net uses a relative namespace path which the SDK's XML library complains about.

The solution is don't include the xmlns attribute in your construction of the SimpleXML element object and use SimpleXMLElement::addAttribute after the fact to add it.

Instead of this:

$element = new SimpleXMLElement('<createTransactionRequest xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd"/>');

Do this:

$element = new SimpleXMLElement('<createTransactionRequest/>');

$element->addAttribute('xmlns', 'AnetApi/xml/v1/schema/AnetApiSchema.xsd');

To avoid these errors when parsing the response, simply strip the xmlns attribute out of the response before parsing it with SimpleXML using the following:

$result = str_replace(' xmlns="AnetApi/xml/v1/schema/AnetApiSchema.xsd"', '', $result);

($result in this example is the raw XML as returned by Authorize.Net.)

I had the same problem on my website https://hoekstra-slotenmaker.nl/ by means of this code it is solved for me in any case:

$ transRequestXmlStr = <<< XML
<? xml version = "1.0" encoding = "UTF-8"?>
<createTransactionRequest xmlns = "http: //AnetApi/xml/v1/enschema/AnetApiSchema.xsd">

I do use a provider that automatically adjusts the XML code for the wordpress websites
