Surround 2 sibling elements with a span

Suppose I have this HTML

<div class="parent">
    <span class="foo">Some text</span>
    <span class="foo">FROM HERE</span>
    <span class="foo">some text</span>
    <span class="foo">TO HERE</span>
    <span class="foo">some text</span>
</div>

Now I'll already have the target elements as $(start) and $(end). I want to make this html on a say a mouseup

<div class="parent">
    <span class="foo">Some text</span>
    <span class="highlight">
        <span class="foo">FROM HERE</span>
        <span class="foo">some text</span>
        <span class="foo">TO HERE</span>
    </span>
    <span class="foo">some text</span>
</div>

and this I want to revert back.

This is related to this question where I already have the 'target elements'.

If it makes it easier, the structure will likely be always as above. A collection of spans within a div. I feel that jQuery nextUntil may be the best approach but I can't quite work it out.

You can wrap a collection of elements in jQuery, by using .wrapAll() and .unwrap():

Fiddle Demo

Adding highlight:

var $wrapped = highlight($start, $end, '.foo'); // highlight and get the highlighted items collection

Removing highlight:

$wrapped.unwrap(); // use unwrap on the collection to remove highlight

Highlight func:

function highlight($start, $end) {
    /** return the wrapped collection **/
    return $start
        .nextUntil($end) // get elements between $start and $end
        .addBack() // add $start back
        .add($end) // add $end
        .wrapAll("<span class='highlight' />"); // wrap them with highlight
}
