HTTP Post of an XML document - Help!

[getmea]

Has anyone coded the UPS Quantum XML code for your site? This api accepts a XML document request with source/destination zip codes and weight. It then sends back a response XML with the shipping cost.

Problem is you need to "post an XML document to their HTTPS site". I have already coded a PHP file which creates the XML request.

But how do I post the document to their site?

How do I parse the XML response back?

I searched but found very few examples I can code from.

Have a look at cURL http://uk2.php.net/curl it will easily allow you to post to and read data from an address. There's examples on that page.

The page contents returned from curl_exec will be the XML document (assuming no errors), this will just be one big string.

Depending on the document you can either extract the result with a regular expression or an XML parser.

Look at xml_parser_create and its related functions or PEAR if you need a XML parser.

Thanks, Speed...I found a functional curl example for posting to a credit card authorization site. All I'd have to do is to make sure to post the xml string as opposed to the example's edi string. Seems easy enough...thanks again.

Just in case someone needs it, I got the code to work. The following is the "guts"...

$url is the full url you need to call
$xmlrequest is the full formatted XML string the receiver needs
...
build your XML request string
...
$ch = curl_init(); // initialize
curl_setopt($ch, CURLOPT_URL, $url); // set the url
curl_setopt($ch, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response
curl_setopt($ch, CURLOPT_POST, 1); // not sure what this one does
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xmlrequest"); // use HTTP POST to send XML data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
### curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment this line if you get no gateway response. ###
$xmlresponse = curl_exec($ch); //execute post and get results
curl_close ($ch); //close the curl interface
...
process your XML response
