RSS/Atom parser

Parses an RSS 2.0 or Atom feed (XML text) and emits one record per feed item. Typically placed after an Http client that downloads the feed.

Summary	string	<description> / Atom summary.
Categories	string	Category names, comma-separated.

Configuration

None besides the common settings.

Behaviour

• For every input the whole feed is parsed and each item is emitted on Output in feed order, with the input's metadata.
• Empty feeds emit nothing. Invalid XML or a document that is neither RSS nor Atom raises an error handled by the flow's error handling.
• The plugin has no memory of earlier runs: every item is emitted on every poll. Filter already processed items yourself (e.g. by Id in a database or script).

Notes

• The plugin is marked "keep alive": a flow that contains it keeps running after its start components finish, as for a listener. Stop the flow explicitly if it is meant to run once.
• For Atom feeds authors are taken from <name>; RSS feeds usually only give an e-mail in <author>, which can end up empty.

Example

No configuration. Placement:

Timer (00:00:15:00) → Http client (GET https://example.com/feed.xml) → RSS/Atom parser → C# script (filter new items) → Mail client
