3 个解决方案

#1

$.get('officers.xml', function(grade){     
  var officer = $(grade).find('officer');

  officer.sort(function(a, b){
     return (parseInt($(a).attr('rank')) - parseInt($(b).attr('rank')));
  });

  officer.each(function(i,v){
    alert($(v).attr('rank'));
  });
});

In case you generate dynamically your xml file on the server the best way is to sort data on the server side. Some discussion is here.

如果您在服务器上动态生成xml文件，最好的方法是在服务器端对数据进行排序。一些讨论在这里。

Something like this should work

这样的事情应该有效

var officers = $('officer'); // unsorted

function matchRank(a, b) {
    return (int)a.attr('rank') - (int)b.attr('rank');
};

officers.sort(matchRank); // sorted

$.get('officers.xml', function(grade){     
  var officer = $(grade).find('officer');

  officer.sort(function(a, b){
     return (parseInt($(a).attr('rank')) - parseInt($(b).attr('rank')));
  });

  officer.each(function(i,v){
    alert($(v).attr('rank'));
  });
});
