Base/Template fo XML

Hi everyone,
I am just getting into the roots/sage system and I am trying to create a custom XML template. Basically I want 4-6 custom XML feeds to be displayed using one base file. Right now I have each XML feed as the following:
[first file is in root of theme] / [2nd file is in templates folder]
base-xmlfeed1.php / xmlfeed1.php
base-xmlfeed2.php / xmlfeed2.php
base-xmlfeed3.php / xmlfeed3.php

This works, but seems like overkill for just running php on each blank base so there is no header and footer.

Any help would be appreciated.
Thank you!
