Removing Dynamically Created Elements

I am creating textboxes dynamically using the following code:

[Code]...

I want to have a function that will remove textboxes and the newline that is created. I have the following function to remove the text boxes but I cant remove the new lines that were created so an empty space is left on the page.function RemoveElement() {

var d = document.getElementById('spanManualInput');
var oldbox = document.getElementById('Value'+i);
d.removeChild(oldbox);
d.removeChild('br');
}
