RSS Filter

A friend wanted to filter an rss feed and extract all the items in one category from it, here is the script. The category in particular was "Anime"

• filter-cgi.pl
• filter-pipe.pl
• filter-entity.pl -- filter to remove entities that break XML::Twig, add more to the list as they are found
• filter-pipe-args.pl -- field to filter and values to match are given as command line arguments
