The Template class is designed for substituting text, not handling logic.
Asking Template to search all variables for valid blocks and then remove
them is going to be _extremely_ inefficient. Instead, when you have multiple
possible blocks where only one block will show, do _not_ set the block that
will show - set and clear the unused block(s).


----- search_results.tpl -----

<h1>Search Results</h1>

<!-- BEGIN list -->
<table>
<!-- BEGIN row -->
<tr>
	<td>{some_data}</td>
</tr>
<!-- END row -->
</table>
<!-- END list -->

<!-- BEGIN no_list -->
<p>No items matched your query.</p>
<!-- END no_list -->


----- search_results.php -----

$t = new Template;
$t->set_file("results", "search_results.tpl");

// do a query here

if(count($results)) {
	$t->set_block("results", "row", "rows");
	// build the list here

	$t->set_block("results", "no_list");
	$t->set_var("no_list", "");
} else {
	$t->set_block("results", "list");
	$t->set_var("list", "");
}
