I suggest you have a quick read of the Tamino documentation.
But I have a few pointers.
Your XML document should conform to the schema you have defined.
You can load this document various ways
Using the Tamino Explorer using the Instance Tab
Using the Tamino Interactive Interface
Using the Tamino Loader
Writing a program in Java VB Jscript etc and using the Tamino apis
