[ERROR] 2018-10-13 07:30:11.771 [[main]\<rss] rss - Invalid RSS feed {:exception=\>#\<RSS::MissingTagError: tag is missing in tag \>}

Hello, folks,

I'm just using ELK, but I'm already totally excited.

However, I already encountered a problem:  
The problem is already known, there is a solution ready, but I can't find the required files on my Ubuntu 18.04!?

Continuing the discussion from [Logstash-input-rss undefined method author](https://discuss.elastic.co/t/logstash-input-rss-undefined-method-author/56916/2):

I'm trying to log RSS feeds, but in some feeds the tag is missing and that's already in the source, it's ATOM and not RSS.

How do I do that? I would add the author myself, but I won't get that far.

Please help!
