How to download generated xml file by a php script

Question

I am using opencart with a module for generating xml feeds of products in real time, so I created option in account of each client to generate the xml file by accessing a link

My question is how can I add download button for the client to be prompted to download the file in computer not to be opened in a new window.

Thanks
