js:

function get_past_issues(year,month) {  
    $.ajax({ url: './demo/Headline/PublicationList.xml', 
         async: false,
         success: function(xml) {
            //$("#dialog").append("<div class = 'issues'>");    
            $(xml).find("Publications").find($("PubYear[Year='" + year + "']")).each(function() {
                //alert ($(this).attr ('Year'));
                    $(xml).find("Publications").find($("PubMonth[Month='" + month + "']")).find("Publication").each(function() {
                        alert ($(this).attr ('ThumbnailPath'));
                    });
            });
            //$("#dialog").append("</div>");    
        }
    });

Na przykład podałem, że rok funkcji to 2012, a miesiąc 12, jednak fliter $ („PubYear [Year =” ”+ rok +” ”)”) nie działa z funkcją find? Jak rozwiązać problem? dzięki
