HTTP::Headers::Util - Header value parsing utility functions
use HTTP::Headers::Util qw(split_header_words); @values = split_header_words($h->header("Content-Type"));
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:
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");
[foo=>'bar', port=>'80,81', discard=> undef], [bar=>'baz' ] ['text/html' => undef, charset => 'iso-8859-1']
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"]);
