我从ajax和onsuccess函数中获取css,我的代码如下：

$(xml).find('item').each(function() {
 var title = $(this).find('title').eq(0).text();
 var url   = $(this).find('content').attr('url');

 // Printing url as undefined
 alert(url);
 console.log($(this).find('content');

});

我想得到的内容url属性我得到项目子项(标题,描述,内容,commentRSS和评论)
但是当我试图获得$(this).find(‘content’)它并没有给我任何东西
任何人都可以弄清楚我做错了什么？
谢谢
