jQuery how to get returned .ajax() element count ?

My attached code calls a Web Service. I am trying to determine if it returns any elements, if none found I can put out a suitable message.

Please check my code, the .size() keeps returning 0, where am I going wrong with this?

[ thanks ]
function fnGetDictDefinition() {

    $.ajaxSetup({ cache: false });

    $.ajax({
      type: "GET",
      url: "http://services.aonaware.com/DictService/DictService.asmx/Define",
      data: "word=" + $("#txtWord").val(),
      dataType: "xml",
      success: function(xml) {
        var name = "";
        var word_def = "";
        var buf = "";
        
        var found = $("xml").find("Definition");
        alert(found.size())

        
        $(xml).find("Definition").each(function() {
          name = $("Name", this).text();
          buf += "<b>Dictionary:</b>&nbsp;" + "<label>" + name + "</label>" + "<br />";
          word_def = $("WordDefinition", this).text();
          buf += "<b>Definition:</b>&nbsp;" + word_def + "<br />";
          buf += name + "<hr />";
        });
        $("#sec01").html(buf);
      },
      error: function(xhr, ajaxOptions, thrownError) {
        alert(xhr.status);
        alert(ajaxOptions);
        alert(thrownError);
      }
    });

}
