function in this code please


$("Item", xmlData).each(function(){
                                var title = $(this).find( "Text" ).text();
                                var url = $(this).find( "Url" ).text();
                                var desc = $(this).find( "Description" ).text();
                                $( '#wiki_article_list' ).append( '<li><a 
class="wikiLinks"
href="'+url+'">'+title+'</a></li>' )

                                        });
