How do I view RSS feed data? I have an RSS source link: https://www.zhihu.com/rss
and I want to have a look at its data, so I type the link in the browser (Safari), but I get the error below: 




  No RSS reader is installed.
  
  Safari can't open "feed:https://www.zhihu.com/rss" because Safari can't display RSS feeds. You can search the Mac App Store for an RSS app.


How can I have a look at its feed data? I know the data is in an XML-like format, but I don't know how to take a look at it.
Open Terminal
cd Documents (or any other suitable directory)
curl -o feed.xml https://www.zhihu.com/rss
Use the text editor of your choice to open feed.xml
