Newbie confusion with xml

[<dale@qc.aira.com>]

 

 

  Ok, I have a million and one questions for you guys but I'm going to take it step by step. The company I work for has an account on Ariba and orders are placed and sent to us through e-mail. We have the option of receiving it in cXML if we specify a URL to send it to. Our overall goal is to convert the info into csv format. We then need to be able to send back an order confirmation and order updates back to Ariba in response to the orderRequest.

 

This is an example of what we would be receiving in the orderRequest.xml, please take a look and I have a few question at bottom...

 

  <?xml version="1.0" encoding="UTF-8" ?>
- <!--

    after the order date).

 

  -->

Now, I'm sure you can see how confusing this can seem to a beginner trying to teach himself.
How would I receive something like this?
What kind of page would I need to catch this information?
How would I send the response?
How can confidential information like this be sent to a URL and be secure from everyone else?

 

Hopefully one of you were once in my situation and can help. Whether you can help with one or all of the questions it would be appreciated because I have alot more than that.

Thank you
