Of course, its just show to you how to get feed by jQuery, then you can make improvement about those code to make it ALPHABETICAL, sort() is your friend. Here my answer, I use SO WordPress tag feed for example, and jQuery Ajax methode base on @haylem answer How to parse an RSS feed using JavaScript?

<script>
jQuery(document).ready(function($) {
        FEED_URL = 'https://stackoverflow.com/feeds/tag?tagnames=wordpress&sort=newest';//feed url
        $.ajax({
            url: document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(FEED_URL),
            dataType: 'json',
            success: function(data) {
                if (data.responseData.feed && data.responseData.feed.entries) {
                    var ul = $('<ul>'),
                        titles = data.responseData.feed.entries.map(function(item) {
                            return item.title;
                        }); //get the titles in array
                    $.each(titles.sort( case_insensitive_comp ) /* sort the titles */,
                    function(i, r) {
                        var li = $('<li/>', {
                                'text': r
                            })
                            .appendTo(ul);
                    });
                    $('#element').html(ul); //output at #element
                }
            }
        })
    });

    //case insensitive base on @Lekensteyn answer at https://stackoverflow.com/a/5286047/1562904
    function case_insensitive_comp( strA, strB ) {
        return strA.toLowerCase().localeCompare( strB.toLowerCase() );
    }
</script>
