someone know about .tmpl file and the syntax of it?

i have something like that and i never saw something similar

<td width="250">
<div class="value"><if:test:yes:no></div>
</td>
<td class="right" width="144">
<div class="value"><var:test2></div>
</td>

now i need to proceed to refactor this code and write foreach loop and i could not find anything in google.

can someone know how to deal with that and there is any documentation in the internet about that?? TNX
