Create script to use data from an XML

VERSION: SAMBAPOS V3.025
SQL server 2012
WANT TO MAKE A “SCRIP” TO USE DATA FROM A “XML” AND PUT THEM IN A BOX OF SAMBAPOS, GREAT IF I WOULD HELP
THANKS

SambaPOS does not support external input for orders as yet.
API, Twitter and other external inputs are on the to do list.

what I want is to put a button which when you press the button the customer record is automatically filled using information from this website “XML”:
