What is a .opml file?
text/x-opml
OPML (Outline Processor Markup Language, .opml) is an XML format for nested outlines. Its most common use is exchanging feed subscription lists between RSS readers, where each outline element carries a feed title and xmlUrl, but it also serves for mind maps and document outlines.
How to use a .opml file
Use an example .opml file to test feed-reader import and export, OPML parsers, and outline tooling, or to move a subscription list between podcast and RSS apps.
