Answer 1

Smerny's answer is working well except that the HTML structure is like:

var s = '
Link Span
';
var $s = $(s);
$s.find("*").not("a,img,br").each(function() {
    $(this).replaceWith(this.innerHTML);
});
console.log($s.html());

The live code is here: http://jsfiddle.net/btvuut55/1/

This happens when there are more than two wrapper outside (two divs in the example above).

Because jQuery reaches the most outside div first, and its innerHTML, which contains span has been retained.

This answer $('#container').find('*:not(br,a,img)').contents().unwrap() fails to deal with tags with empty content.

A working solution is simple: loop from the most inner element towards outside:

var $elements = $s.find("*").not("a,img,br");
for (var i = $elements.length - 1; i >= 0; i--) {
    var e = $elements[i];
    $(e).replaceWith(e.innerHTML);
}
