Im new to XML and my job needs me to communicate with a web site. I received the interface specifications for communicating with the particular web site. Here is the first paragraph of the manual.

"This document contains the interface specifications for communicating with the Rx.com SBMO System. This system uses version 1.0 XML for all messages. All communication is performed via https, using SSL and certificates. All messages are initiated by the store system and Rx.com SBMO system responds real-time to each request"

That being said, the manual gives all the examples needed for each task. My basic questions are:

Once I have created the .XML documents what do I do with them? How do I run them? Am I missing a basic component to using these .XML files?

Sorry if these are really obvious questions, but Im quite stuck.

Thx for any information
