This module provides basic functions for parsing mime-type names and matching them against a list of media-ranges.

See section 14.1 of RFC 2616 (the HTTP specification) for a complete explanation. More information on the library can be found in the XML.com article Just use Media Types?

Contents

parse_mime_type() Parses a mime-type into its component parts. parse_media_range() Media-ranges are mime-types with wild-cards and a 'q' quality parameter. quality() Determines the quality ('q') of a mime-type when compared against a list of media-ranges. quality_parsed() Just like quality() except the second parameter must be pre-parsed. fitness_and_quality_parsed() Just like quality_parsed() but also returns the fitness score. best_match() Choose the mime-type with the highest fitness score and quality ('q') from a list of candidates.

UsageIn Erlang1> mimeparse:best_match(["application/xbel+xml", "text/xml"], "text/*;q=0.5,*/*; q=0.1").
"text/xml"Note that neither quality_parsed() nor fitness_and_quality_parsed() are exported from the Erlang version.

text/xmlThis example uses the Rhino JavaScript shell but usage should be similar for other JavaScript environments.
