我试图检索图像（与其他内容一起） media:content为每个岗位在一个RSS feed： http://bits.blogs.nytimes.com/feed/
我试过此链接（与许多人一起） jQuery的XML解析如何获取元素的属性 ，但我仍然得到错误。
有一个PHP文件以及（参见下图），但我不认为这是问题。
我已尝试若干变化和我正在与结束了<img src="undefined" alt="image">
这就是日志说TypeError: 'undefined' is not an object (evaluating '$item.find('media\\:content').attr('url').text')
这里是（我想要抓住什么是URL =“此值”）从RSS提要的XML的例子<media:content url="http://graphics8.nytimes.com/images/2011/11/30/technology/bits-daily-report/bits-daily-report-thumbStandard.jpg" medium="image" width="75" height="75"></media:content>
这是我与jQuery嵌入式HTML。 感谢您所有的解决方案，指针和建议。 我现在正在打一个路障。
