Delete a hidden field by its value

I have a page with some values that looks like this:

 <div id="productList" >
   <input type="hidden" name="product[0].id" value="21">
   <div id="21" >BeanCounter</div>
   <input type="hidden" name="product[1].id" value="22">
   <div id="22" >CallGate</div>
</div>

Now I want to delete the hidden field with value=21 and the div with id=21.

I have this:

function remove(id){
    var remove = $(id);
    $('productList').removeChild(remove);

But how do I delete the hidden field? Can you get an object by its value?

edit missed the mootools tag, not sure where the jquery tag came from. I guess mootools isn't that common but hopefully this could be done with plain javascript.

Hmm tag got changed back to jquery again?

Using plain javascript as mentioned in the edited post:

var checkVal = '21';

var parentDiv = document.getElementById('productList');
var inps = parentDiv.getElementsByTagName('input');
var inpRemove = null;

//Get the div to be removed
var divRemove = document.getElementById(checkVal);

for(var i=0; i<inps.length; i++)
{
   if(inps[i].value == checkVal)
   {
      //Get the input to be removed (Assuming only input with same value)
      inpRemove = inps[i];
      break;
   }
}

//Remove both here
parentDiv.removeChild(inpRemove);
parentDiv.removeChild(divRemove);

Mootools solution:

function remove(id){
    $('productList').getElements('input[value="' + id + '"], div[id="' + id + '"]').destroy();
}

jQuery solution:

function remove(id){
    $('input[value="' + id + '"], div[id="' + id + '"]').remove();
}
