Class Method Details

.parse(xml, opts = {}) ⇒ Object

Parses the given xml and attempts to return a normalized Feed object. Setting forced parser to a suitable parser will mean that parser is used first, and if try_others is false, it is the only parser used, otherwise all parsers in the ParserRegistry are attempted next, in order of priority.
