great palces to get you started on XML parseing
try the second one first as it jumps right into it with xpat.

Subject: [PHP] XML Parsing
> I am posting information to a credit card processing server. This is done
> over HTTPS (with cURL) and seems to work fine. I get the response that I
> want from the server, which consists of an XML doc with about 20 tags and
> their corresponding values. I have gone through the mailing list and
> manuals, yet I still can't seem to figure out how to get each piece of the
> XML doc into their own variables.

> Here is the code I am using:

> $server = "https://www.creditcard.com";;
> $path = "xmlhttps/xtrans.asp";
> $ch = curl_init();
> $requestedurl = "$server" . "/$path";
> curl_setopt($ch, CURLOPT_URL, "$requestedurl");
> curl_setopt($ch, CURLOPT_POST, 1);
> curl_setopt($ch, CURLOPT_POSTFIELDS, "$xmlstring");
> curl_setopt($ch, CURLOPT_RETURNTRANSFER,0);

> curl_close ($ch);
