I'm looking to integrate EFSnet's payment gateway interface into a client application. I haven't done much work with XML (although I understand the basics), so I'm looking for suggested XML modules to get this work done.

A sample HTTPS POST would go like this: 
<Request StoreID="myStoreID" StoreKey="myStoreKey" ApplicationID="EFSn
+et samples 1.0">
<CreditCardAuthorize>
<ReferenceNumber>1234</ReferenceNumber>
<TransactionAmount>1.00</TransactionAmount>
<AccountNumber>4111111111111111</AccountNumber>
<ExpirationMonth>12</ExpirationMonth>
<ExpirationYear>99</ExpirationYear>
</CreditCardAuthorize>
</Request>

And the reply: 
<Reply>
<TransactionReply>
<ResponseCode>0</ResponseCode>
<ResultCode>00</ResultCode>
<ResultMessage>APPROVED</ResultMessage> 
<TransactionID>100000182165</TransactionID>
<AVSResponseCode />
<CVVResponseCode />
<ApprovalNumber>123456</ApprovalNumber>
<AuthorizationNumber>123456</AuthorizationNumber>
<TransactionDate>021112</TransactionDate>
<TransactionTime>110544</TransactionTime>
<ReferenceNumber>1234</ReferenceNumber>
<AccountNumber>XXXXXXXXXXXX1111</AccountNumber>
<TransactionAmount>1.00</TransactionAmount> 
</TransactionReply>
</Reply>

Any suggestions on what I might use to a) markup and send the HTTPS POST (XML) connection, and b) accept/parse the reply?

Thanks in advance,
