What'd be reliable perl lib / module to remove a certain html element located by its nth order from the top/start of file, e.g: 
<body>   

<nav a=b>   

 <div>   
 </div>   
</nav>   
  
<div>   
</div>   

<nav c=d>    
  <li> </li>      
</nav>   

</body>

[download]
so if input to that module function 1,nav will remove only first encountered <nav> ...</nav> wholly or if input 2,nav will remove only second encountered <nav> ...</nav> wholly etc
