NAME

HTTP::Headers::Util - Header value parsing utility functions

SYNOPSIS

use HTTP::Headers::Util qw(split_header_words);
@values = split_header_words($h->header("Content-Type"));

DESCRIPTION

This module provide a few functions that helps parsing and construction of valid header values. None of the functions are exported by default.

The following functions are provided:

split_header_words( @header_values )

This function will split the header values given as argument into a list of anonymous arrays containing key/value pairs. The function know how to deal with ",", ";" and "=" as well as quoted values. Multiple values are treated as if they were separated by comma.

This is easier to describe with an example:

split_header_words('foo="bar"; port="80,81"; discard, bar=baz')
split_header_words('text/html; charset="iso-8859-1");

will return

[foo=>'bar', port=>'80,81', discard=> undef], [bar=>'baz' ]
['text/html' => undef, charset => 'iso-8859-1']

join_header_words( @arrays )

This will do the opposite convertion of what split_header_words() does. It takes a list of anonymous arrays as argument and produce a single header value. Attribute values are quoted if needed. Example:

join_header_words(["text/plain" => undef, charset => "iso-8859/1"]);
