previousElementSibling property

Browser support:
Returns a reference to the previous child element of the current element's parent.
Note: The previousElementSibling property is supported in Firefox from version 3.5 and Internet Explorer from version 9.
The previous sibling node and the previous sibling element can be different. A node is an element node if it's nodeType is 1 (Node.ELEMENT_NODE). Text nodes and comment nodes are not element nodes. If you need the previous sibling node of an element, use the previousSibling property.

The children collection contains all child elements of an element in source order. If you want to iterate through the child elements of an element, you can also use it.

Note: The children collection also contains the child comment nodes in Internet Explorer before version 9. In other browsers, it only contains the element nodes.
Similarly to the previousElementSibling property, the nextElementSibling property returns the next sibling element of an element, furthermore the firstElementChild and lastElementChild properties return the first and last child element of an element.

                    alert (child.innerHTML);
                    child = child.previousElementSibling;
            else {
                var child = list.lastChild;
                while (child) {
                    if (child.nodeType == 1 /*Node.ELEMENT_NODE*/) {
                        alert (child.innerHTML);
                    child = child.previousSibling;
    <ol id="myList">
    <button onclick="GetListItems ();">Get the list items backwards!</button>
