Improve the BBC News RSS feed by (a) filtering out sport, iplayer links, and BBC sounds links; and (b) stripping the anchor (#0, #1, #2 etc.) off <guid>s so "republished to front page" stories don't re-appear in your feed reader

# Dependencies:
# * open-uri - load remote URL content easily
# * nokogiri - parse/filter XML
gemfile do
  source 'https://rubygems.org'

# Regular expression describing the GUIDs to reject from the resulting RSS feed
# We want to drop everything from the "sport" section of the website, also any iPlayer/Sounds/Ideas links
REJECT_GUIDS_MATCHING = /^https:\/\/www\.bbc\.(co\.uk|com)\/(sport|iplayer|sounds|ideas|news\/videos|programmes)\//

REJECT_TITLES_MATCHING = /^(BBC News app)$/

# Load and filter the original RSS
rss = Nokogiri::XML(open('https://feeds.bbci.co.uk/news/rss.xml?edition=uk'))
rss.css('item').select{|item|
  item.css('guid').text =~ REJECT_GUIDS_MATCHING ||
  item.css('title').text =~ REJECT_TITLES_MATCHING
}.each{|item| item.swap("<!-- [REJECTED] #{item.to_s.gsub(/--/, '[hyphen][hyphen]')} -->")}

# Strip the anchors off the <guid>s: BBC News "republishes" stories by using guids with #0, #1, #2 etc, which results in duplicates in feed readers
rss.css('guid').each{|g|g.content=g.content.gsub(/#.*$/,'')}

# Now there might be duplicate <guid>s, which is usually harmless but isn't pretty (and violates the spec). Let's remove the dupes.
rss.css('guid').map(&:text).each do |guid|
  matching_items = rss.css('item').select{|item| item.css('guid').text == guid }
  duplicate_items = matching_items[1..-1]
  duplicate_items.each{|item| item.swap("<!-- [DUPLICATE] #{item.to_s.gsub(/--/, '[hyphen][hyphen]')} -->")}
end

# Tag us as the generator
generator = rss.css('generator')[0]
generator.content = "Dan Q's 'BBC News without the crap' <https://danq.me/2024/03/09/bbc-news-without-the-crap/> generator. Was: #{generator.content}"

# Update the src to us:
rss.xpath('//atom:link').attr('href', 'https://fox.q-t-a.uk/bbc-news-no-sport.xml')

Updated today after the Beeb started injecting ads for iPlayer and the BBC News app into their "news" RSS feed.
