local http = require("socket.http")
local feedparser = require("feedparser")

local feed_url = "https://mitjafelicijan.com/index.xml"

local response, status, _ = http.request(feed_url)
if status == 200 then
  local parsed = feedparser.parse(response)

  -- Print out feed details.
  print("> Title   ", parsed.feed.title)
  print("> Author  ", parsed.feed.author)
  print("> ID      ", parsed.feed.id)
  print("> Entries ", #parsed.entries)
