How can I read a .atom file offline?
Google+ is eliminating some of its features, and is giving users a chance to archive their data until March 31, 2019. I did so, but, the downloaded .zip file contains .atom files, which, basically, are .xml, files. I tried openning them in my browsers, but, it shows the XML layout/tags along with the plain-text content; though I can see the plain-text, I don't want to see the XML. I searched the web and browser extensions for something that can read .atom (or .xml) files and display them without the XML layout/tags, but, none do what I want, which, to me, at least, seems awful simple! All .atom readers that I've found require logins or access to RSS feeds, which I don't want or need. Google gives no information about .atom files in its links/pages for the Google+ removal/archive; it doesn't even mention the fact, which will cause chaos among non-computer people who want to see their useless (to them) downloaded archived info.
All I want is to read the .atom files offline, in plain-text, formatted without XML, so that a human being can read it without having to figure out what's what. If there is such a thing, please give me the link.
P.S. I'm a computer programmer and webmaster, who can, probably, write a simple program to do what I want, but, I'm lazy, and figure somebody else has already done the grunt work. I can't believe I'm the only person who wants something like this!
