问题描述
我尝试使用jfeed提取的RSS能够获得成功的响应，但是，我真正想要的是内容. [内容:已编码]我需要这个，这样我就可以从每个帖子中获取第一张图片.
I can get a successful response with the RSS I am trying to pull using jfeed, however, the thing I really want is the content. [content:encoded] I need this so I can grab the first image from each post.
我认为更新jfeed可以很容易地做到这一点，但是我尝试的一切似乎都没有.最明显的尝试是添加:
I figured it would be easy to update jfeed to do this, but nothing I try seems to get it. The most obvious attempt was to add:
item.content = jQuery(this).find('content\:encoded').eq(0).text();
但是这将返回一个空字符串.非常感谢朝正确方向的推动，谢谢大家！
but this returns an empty string. I'd really appreciate a push in the right direction, thanks all!
推荐答案
注意:不了解jfeed，但是我已经使用了很多feed解析器.
Caveat: Don't know jfeed, but I've used lots of feed parsers.
有了这个警告，为什么还要在冒号前面加一个斜线?您不需要这样做.
With that caveat, why do you prefix the colon with a slash? You should not need to do that.
此外，某些提要解析器不支持名称空间.由于content是名称空间前缀，因此jfeed可能无法在其上进行find().在这种情况下，您需要尝试.find('encoded')，省略名称空间前缀.
Also, some feed parsers are not namespace aware. Since content is a namespace prefix, it's possible that jfeed is not able to find() on that. In that case, you would need to try .find('encoded'), omitting the namespace prefix.
该提要(或该提要中的某些项目)也可能没有content:encoded元素.那是RSS的扩展，不是必需的元素.
It's also possible that that feed (or certain items in that feed) don't have the content:encoded element. That's an extension of RSS and not a required element.
