OPMLHeader Event
Fired for each value in the Header section of the current OPML document.
Syntax
rss.on('OPMLHeader', listener: (e: {readonly field: string, readonly value: string}) => void )
Remarks
This event is fired when the class is parsing an OPML document after a call to ReadOPML is made. The class parses each header field and value from the OPML document and fires OPMLHeader once for each header present.
