You said that the block 'top' needs to contain multiple 'item's and multiple
'block's. I am leaving out the 'top' block because you didn't say anything
about looping through multiple tops - if you need to do that it works the
same way.

##### template.html #####

<!-- this was a block named top -->
<!-- BEGIN item -->
<!-- BEGIN links -->
	{link}
<!-- END links -->
<!-- END item -->
<!-- BEGIN block -->
	(block_links)
<!-- END block -->
<!-- this was a block named top -->


###### page.php ######

$t = new Template;
$db = $db2 = new DB_Whatever;

$t->set_file("file", "template.html");

$t->set_block("file", "item", "items");
$t->set_block("item", "links", "item_links");
$t->set_block("file", "block", "blocks");

// dummy queries - you've got your data retrieval figured out

// get all of the 'item's

$db->query("select item from some_table");
while($db->next_record()) {
	
	// get all of the 'item' links
	
	$db2->query(sprintf("select link from item_links_table where item =
'%s'", $db->f("item")));
	while($db2->next_record()) {
		$t->set_var($db2->Record);
		$t->parse("item_links", "links", true);
	}
	
	$t->parse("items", "item", true);
	$t->set_var("item_links", "");
}


// now get all of the 'block's

$db->query("select block from some_table");
while($db->next_record()) {
	
	// get all of the 'block' links
	
	$db2->query(sprintf("select link from block_links_table where block
= '%s'", $db->f("block")));
	while($db2->next_record()) {
		$t->set_var($db2->Record);
		$t->parse("block_links", "links", true);
	}
	
	$t->parse("blocks", "block", true);
	$t->set_var("block_links", "");
}

$t->pparse("file");
