XML wont parse???

[Nicksta]

Hi Guys.

A payment gateway needs me to post them information in exchange for an xml feed with the payment information.

So what I have done is the following :

$url = "http://www.setcom.com/secure/components/synchro.cfc?wsdl"; 
$ch = curl_init();    // initialize curl handle 
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 0); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable 
curl_setopt($ch, CURLOPT_TIMEOUT, 20); // times out after 4s 
curl_setopt($ch, CURLOPT_POST, 1); // set POST method 
curl_setopt($ch, CURLOPT_POSTFIELDS, "method=tnx_synchro&identifier=1234567890&usrname=[e-mail]&pwd=testseller&tnxid=B43DDDD3-BB5D-4CD4-8621-65FA4EE149F2&checksum=4F49DE1B953A71836AEA8D95424B3CE1&parity=9002344"); 
$result = curl_exec($ch);
curl_close($ch);  

print_r($result);

Now - the result that prints on the screen seems perfect

<?xml version="1.0" encoding="UTF-8"?><tnx_synchro><outcome><status>Complete</status><transaction_id>b43dddd3-bb5d-4cd4-8621-65fa4ee149f2</transaction_id></outcome><member><identifier>1234567890</identifier><username>[e-mail]</username><reference>1234568039</reference></member><buyer><username>[e-mail]</username><shipping_address><email_address/><street1/><street2/><city/><state/><zip/><country/></shipping_address><billing_address><email_address/><street1/><street2/><city/><state/><zip/><country/></billing_address></buyer><payment_instrument><type>Credit Card</type><brand>MasterCard</brand><card_name>Setcom Test Buyer</card_name><card_number>XXXX-XXXX-XXXX-5454</card_number></payment_instrument><financial><amount_total>200</amount_total><currency>ZAR</currency></financial><line_items count="1"><lid><sku>CODE</sku><description>Product Description</description><price>200</price><quantity>1</quantity><weight>0</weight><height>0</height><width>0</width><length>0</length><color/><size/><handling>0</handling><require_shipping>0</require_shipping><is_voucher>0</is_voucher></lid></line_items><transactions count="1"><transaction_id>b43dddd3-bb5d-4cd4-8621-65fa4ee149f2</transaction_id><type>funds_purchase</type><seller_reference>1234568039</seller_reference><buyer_reference/><statement row="1"><type>funds_received</type><date_added>20050726172021</date_added><reference>2831</reference><error_code>0</error_code><authorization_number/><transaction_key/><amount>200</amount><fee>-410</fee><tax>-57</tax><rolling_reserve>0</rolling_reserve><nett>-267</nett><balance>10504481</balance><rolling_reserve_balance>0</rolling_reserve_balance><funds_available>20050726172021</funds_available><rolling_reserve_available>20050726172021</rolling_reserve_available></statement></transactions></tnx_synchro>

Now the problem is decoding this information and putting it into variables.

I have tried to use RPCXML parser to parse the information, with no luck :

$response = $result;
		$data = XML_unserialize(substr($response, strpos($response, "\r\n\r\n")+4));

	$return = array();
	$return[0] = true;
	$return[1] = XMLRPC_adjustValue(&$data['tnx_synchro']['outcome']['status']);

Keeps on getting blank arranys. Tried a number of parsers and nothing seems to work. Would it be the way that I am getting the information from the gateway??

Please guys help me out if you know how - spend almost 2 weeks researching with no luck 🙁

Thanks,

Nick

Hi,

It seems that you are getting the information from the gateway correctly. I haven't checked, but that xml seems pretty valid.

I'm not familiar with the RPCXML parser, so I can't help you with that (or vouch for it for that matter... heh). However, I have found that the traditional XML parser functions tend to work fine most of the time. Search for the xml_parser_create() function on php.net and give that a try. There's some pretty decent example code in the "XML parser functions" section of the php manual.

For my current project, I ended up writing an XMLParser class to encapsulate all the nasty procedural callback paradigm into a nice OO package. Maybe you would want to do the same?

You mention you have tried a number of parsers. If you've tried this one, just disregard this... 😉
