NAME
Parse::MIME - Parse mime-types, match against media ranges
VERSION
version 1.003
SYNOPSIS
use Parse::MIME qw( best_match ); print best_match( [ qw( application/xbel+xml text/xml ) ], 'text/*;q=0.5,*/*; q=0.1' ); # text/xml
DESCRIPTION
This module provides basic functions for handling mime-types. It can handle matching mime- types against a list of media-ranges. See section 14.1 of the HTTP specification [RFC 2616] for a complete explanation: <http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1>
INTERFACE
None of the following functions are exported by default. You can use the ":all" tag to import all of them into your package: use Parse::MIME ':all'; parse_mime_type Parses a mime-type into its component parts and returns type, subtype and params, where params is a reference to a hash of all the parameters for the media range: parse_mime_type 'application/xhtml;q=0.5' # ( 'application', 'xhtml', { q => 0.5 } ) parse_media_range Media-ranges are mime-types with wild-cards and a "q" quality parameter. This function works just like "parse_mime_type", but also guarantees that there is a value for "q" in the params hash, supplying the default value if necessary. parse_media_range 'application/xhtml' # ( 'application', 'xhtml', { q => 1 } ) parse_media_range_list Media-range lists are comma-separated lists of media ranges. This function works just like "parse_media_range", but accepts a list of media ranges and returns for all of media- ranges. my @l = parse_media_range_list 'application/xhtml, text/html;q=0.7' # ( 'application', 'xhtml', { q => 1 }, 'text', 'html', { q => 0.7 } ) fitness_and_quality_parsed Find the best match for a given mime-type (passed as the first parameter) against a list of media ranges that have already been parsed by "parse_media_range" (passed as a flat list). Returns the fitness value and the value of the "q" quality parameter of the best match, or "( -1, 0 )" if no match was found. # for @l see above fitness_and_quality_parsed( 'text/html', @l ) # ( 110, 0.7 ) quality Determines the quality ("q") of a mime-type (passed as the first parameter) when compared against a media-range list string. F.ex.: quality( 'text/html', 'text/*;q=0.3, text/html;q=0.7, text/html;level=1, text/html;level=2;q=0.4, */*;q=0.5' ) # 0.7 quality_parsed Just like "quality", except the second parameter must be pre-parsed by "parse_media_range_list". best_match Choose the mime-type with the highest quality ("q") from a list of candidates. Takes an array of supported mime-types as the first parameter and finds the best match for all the media-ranges listed in header, which is passed as the second parameter. The value of header must be a string that conforms to the format of the HTTP "Accept" header. F.ex.: best_match( [ qw( application/xbel+xml text/xml ) ], 'text/*;q=0.5,*/*; q=0.1' ) # 'text/xml'
