wp_nav_menu to output shortcode

Hi forumers,

For a specific project, I am trying to output shortcode via the wp_nav_menu.

<?php

$defaults = array(
	'theme_location'  => '',
	'menu'            => '',
	'container'       => 'div',
	'container_class' => '',
	'container_id'    => '',
	'menu_class'      => 'menu',
	'menu_id'         => '',
	'echo'            => true,
	'fallback_cb'     => 'wp_page_menu',
	'before'          => '',
	'after'           => '',
	'link_before'     => '',
	'link_after'      => '',
	'items_wrap'      => '<ul id="%1$s" class="%2$s">%3$s</ul>',
	'depth'           => 0,
	'walker'          => ''
);

wp_nav_menu( $defaults );

?>

Above is the default wp_nav_menu

The output that is required would be:
[button text="%3$s" link="MenuItemLink" size="large" style="default" target="_self"]

I will have to remove the container as WP only allows ul or div. But how do I go about adding the link for that specific menu item ?

Any help is much appreciated.

Thanks.
