don't display shortcode attribute if empty… easier way?

Hello,

I have a shortcode… that I have been using.. So my issue is that if one of the attributes is empty.. i don’t want it to display the html once the page is published ( when viewsource or other methods are used)

Question is:

1. is there a way or check to do it for all the attributes at once? instead of writing if else if statements?

2 if not is there a proper method that doesn’t require lots of if statements?

Basically in the code I have posted..

if type is empty , not to display any part of the
<i class="fa fa-"'.$type.'"></i>

function demo_item_box( $atts, $content = null )
{
	extract(shortcode_atts(array(
		'image' => '',
		'title' => '',
		'type' => '',
		'link' => '',
		'linktitle' => 'Read more',
		'target' => '_blank',
	), $atts));

	$output = '<div class="test_box">';
	if( $link )  $output .= '<a href="'. $link .'">';
	$output .= '<img src="'. $image .'" alt="'. $title .'" />';
	if( $link )  $output .= '</a>';
	$output .= '</div>';
	$output .= '<div class="desc">';
	$output .= '<i class="fa fa-"'.$type.'"></i>'.'<h4>' .  $title .'</h4>';
	$output .= '<p>'. do_shortcode( $content ) .'</p>';
	$output .= '</div>';
	$output .= '</div>';
	return $output;
}
add_shortcode("test", "demo_test_box");
