mimeparse - Basic functions for handling mime-types in Erlang, JavaScript, Perl, PHP, Python, Ruby, Java

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?

`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.

Usage

In Erlang

1> 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.

In JavaScript

Rhino 1.7 release 1 2008 03 06
js> load('mimeparse.js');
js> Mimeparse.bestMatch(['application/xbel+xml', 'text/xml'], 'text/*;q=0.5,*/*; q=0.1');
text/xml

This example uses the Rhino JavaScript shell but usage should be similar for other JavaScript environments.

In Perl

use MIMEParse qw( best_match );
print best_match(['application/xbel+xml', 'text/xml'], 'text/*;q=0.5,*/*; q=0.1');
# text/xml

In PHP

include_once 'mimeparse.php';

echo Mimeparse::best_match(array('application/xbel+xml', 'text/xml'),
  'text/*;q=0.5,*/*; q=0.1');
    ==>"text/xml"

In Python

>>> import mimeparse
>>> mimeparse.best_match(['application/xbel+xml', 'text/xml'], 
      'text/*;q=0.5,*/*; q=0.1')
'text/xml'

In Ruby

require "mimeparse"
    ==>true
MIMEParse.best_match(['application/xbel+xml', 'text/xml'],
  'text/*;q=0.5,*/*; q=0.1')
    ==>"text/xml"

In Java

List<String> mimeTypesSupported = Arrays.asList(StringUtils.split(
                "application/xbel+xml,text/xml", ','));
String bestMatch = MIMEParse.bestMatch(mimeTypesSupported, "text/*;q=0.5,*/*;q=0.1");

In Go

import "mimeparse"

bestmatch := mimeparse.BestMatch(["application/xbel+xml", "text/xml"], 
  "text/*;q=0.5,*/*; q=0.1");
