In particular, parse comma-separated lists where the elements of the list may include quoted-strings. A quoted-string could contain a comma. A non-quoted string could have quotes in the middle. Quotes are removed automatically after parsing. It basically works like :func:`parse_set_header` just that items may appear multiple times and case sensitivity is preserved. The return value is a standard :class:`list`: >>> parse_list_header('token, "quoted value"') ['token', 'quoted value'] To create a header from the :class:`list` again, use the :func:`dump_header` function. :param value: a string with a list header. :return: :class:`list` :rtype: list Nr �"r_ r_ )�_parse_list_header�unquote_header_value�append)ro �result�itemr0 r0 r1 �parse_list_header8 s (ry c C s| i }xrt | �D ]f}d|kr$d||< q|jdd�\}} | dd� | dd� koVdkn rlt| dd� �} | ||< qW |S )a^ Parse lists of key, value pairs as described by RFC 2068 Section 2 and convert them into a python dict: >>> d = parse_dict_header('foo="is a fish", bar="as well"') >>> type(d) is dict True >>> sorted(d.items()) [('bar', 'as well'), ('foo', 'is a fish')] If there is no value for a key it will be `None`: >>> parse_dict_header('key_without_value') {'key_without_value': None} To create a header from the :class:`dict` again, use the :func:`dump_header` function. :param value: a string with a dict header. :return: :class:`dict` :rtype: dict �=Nr rs r_ r_ )rt r* ru )ro rw rx r\ r0 r0 r1 �parse_dict_headerX s ( r{ c C s^ | rZ| d | d ko dkn rZ| dd � } | sF| dd� dkrZ| j dd�j dd�S | S ) z�Unquotes a header value.
