- '''Get the character encoding of the XML document
-
- http_headers is a dictionary
- xml_data is a raw string (not Unicode)
-
- This is so much trickier than it sounds, it's not even funny.
- According to RFC 3023 ('XML Media Types'), if the HTTP Content-Type
- is application/xml, application/*+xml,
- application/xml-external-parsed-entity, or application/xml-dtd,
- the encoding given in the charset parameter of the HTTP Content-Type
- takes precedence over the encoding given in the XML prefix within the
- document, and defaults to 'utf-8' if neither are specified. But, if
- the HTTP Content-Type is text/xml, text/*+xml, or
- text/xml-external-parsed-entity, the encoding given in the XML prefix
- within the document is ALWAYS IGNORED and only the encoding given in
- the charset parameter of the HTTP Content-Type header should be
- respected, and it defaults to 'us-ascii' if not specified.
-
- Furthermore, discussion on the atom-syntax mailing list with the
- author of RFC 3023 leads me to the conclusion that any document
- served with a Content-Type of text/* and no charset parameter
- must be treated as us-ascii. (We now do this.) And also that it
- must always be flagged as non-well-formed. (We now do this too.)
-
- If Content-Type is unspecified (input was local file or non-HTTP source)
- or unrecognized (server just got it totally wrong), then go by the
- encoding given in the XML prefix of the document and default to
- 'iso-8859-1' as per the HTTP specification (RFC 2616).
-
- Then, assuming we didn't find a character encoding in the HTTP headers
- (and the HTTP Content-type allowed us to look in the body), we need
- to sniff the first few bytes of the XML data and try to determine
- whether the encoding is ASCII-compatible. Section F of the XML
- specification shows the way here:
- http://www.w3.org/TR/REC-xml/#sec-guessing-no-ext-info
-
- If the sniffed encoding is not ASCII-compatible, we need to make it
- ASCII compatible so that we can sniff further into the XML declaration
- to find the encoding attribute, which will tell us the true encoding.
-
- Of course, none of this guarantees that we will be able to parse the
- feed in the declared character encoding (assuming it was declared
- correctly, which many are not). CJKCodecs and iconv_codec help a lot;
- you should definitely install them if you can.

-#REVISION HISTORY
-#1.0 - 9/27/2002 - MAP - fixed namespace processing on prefixed RSS 2.0 elements,
-# added Simon Fell's test suite
-#1.1 - 9/29/2002 - MAP - fixed infinite loop on incomplete CDATA sections
-#2.0 - 10/19/2002
-# JD - use inchannel to watch out for image and textinput elements which can
-# also contain title, link, and description elements
-# JD - check for isPermaLink='false' attribute on guid elements
-# JD - replaced openAnything with open_resource supporting ETag and
-# If-Modified-Since request headers
-# JD - parse now accepts etag, modified, agent, and referrer optional
-# arguments
-# JD - modified parse to return a dictionary instead of a tuple so that any
-# etag or modified information can be returned and cached by the caller
-#2.0.1 - 10/21/2002 - MAP - changed parse() so that if we don't get anything
-# because of etag/modified, return the old etag/modified to the caller to
-# indicate why nothing is being returned
-#2.0.2 - 10/21/2002 - JB - added the inchannel to the if statement, otherwise its
-# useless. Fixes the problem JD was addressing by adding it.
-#2.1 - 11/14/2002 - MAP - added gzip support
-#2.2 - 1/27/2003 - MAP - added attribute support, admin:generatorAgent.
-# start_admingeneratoragent is an example of how to handle elements with
-# only attributes, no content.
-#2.3 - 6/11/2003 - MAP - added USER_AGENT for default (if caller doesn't specify);
-# also, make sure we send the User-Agent even if urllib2 isn't available.
-# Match any variation of backend.userland.com/rss namespace.
-#2.3.1 - 6/12/2003 - MAP - if item has both link and guid, return both as-is.
-#2.4 - 7/9/2003 - MAP - added preliminary Pie/Atom/Echo support based on Sam Ruby's
-# snapshot of July 1 <http://www.intertwingly.net/blog/1506.html>; changed
-# project name
-#2.5 - 7/25/2003 - MAP - changed to Python license (all contributors agree);
-# removed unnecessary urllib code -- urllib2 should always be available anyway;
-# return actual url, status, and full HTTP headers (as result['url'],
-# result['status'], and result['headers']) if parsing a remote feed over HTTP --
-# this should pass all the HTTP tests at <http://diveintomark.org/tests/client/http/>;
-# added the latest namespace-of-the-week for RSS 2.0
-#2.5.1 - 7/26/2003 - RMK - clear opener.addheaders so we only send our custom
-# User-Agent (otherwise urllib2 sends two, which confuses some servers)
-#2.5.2 - 7/28/2003 - MAP - entity-decode inline xml properly; added support for
-# inline <xhtml:body> and <xhtml:div> as used in some RSS 2.0 feeds
-#2.5.3 - 8/6/2003 - TvdV - patch to track whether we're inside an image or
-# textInput, and also to return the character encoding (if specified)
-#2.6 - 1/1/2004 - MAP - dc:author support (MarekK); fixed bug tracking
-# nested divs within content (JohnD); fixed missing sys import (JohanS);
-# fixed regular expression to capture XML character encoding (Andrei);
-# added support for Atom 0.3-style links; fixed bug with textInput tracking;
-# added support for cloud (MartijnP); added support for multiple
-# category/dc:subject (MartijnP); normalize content model: 'description' gets
-# description (which can come from description, summary, or full content if no
-# description), 'content' gets dict of base/language/type/value (which can come
-# from content:encoded, xhtml:body, content, or fullitem);
-# fixed bug matching arbitrary Userland namespaces; added xml:base and xml:lang
-# tracking; fixed bug tracking unknown tags; fixed bug tracking content when
-# <content> element is not in default namespace (like Pocketsoap feed);
-# resolve relative URLs in link, guid, docs, url, comments, wfw:comment,
-# wfw:commentRSS; resolve relative URLs within embedded HTML markup in
-# description, xhtml:body, content, content:encoded, title, subtitle,
-# summary, info, tagline, and copyright; added support for pingback and
-# trackback namespaces
-#2.7 - 1/5/2004 - MAP - really added support for trackback and pingback
-# namespaces, as opposed to 2.6 when I said I did but didn't really;
-# sanitize HTML markup within some elements; added mxTidy support (if
-# installed) to tidy HTML markup within some elements; fixed indentation
-# bug in _parse_date (FazalM); use socket.setdefaulttimeout if available
-# (FazalM); universal date parsing and normalization (FazalM): 'created', modified',
-# 'issued' are parsed into 9-tuple date format and stored in 'created_parsed',
-# 'modified_parsed', and 'issued_parsed'; 'date' is duplicated in 'modified'
-# and vice-versa; 'date_parsed' is duplicated in 'modified_parsed' and vice-versa
-#2.7.1 - 1/9/2004 - MAP - fixed bug handling " and '. fixed memory
-# leak not closing url opener (JohnD); added dc:publisher support (MarekK);
-# added admin:errorReportsTo support (MarekK); Python 2.1 dict support (MarekK)
-#2.7.4 - 1/14/2004 - MAP - added workaround for improperly formed <br/> tags in
-# encoded HTML (skadz); fixed unicode handling in normalize_attrs (ChrisL);
-# fixed relative URI processing for guid (skadz); added ICBM support; added
-# base64 support
-#2.7.5 - 1/15/2004 - MAP - added workaround for malformed DOCTYPE (seen on many
-# blogspot.com sites); added _debug variable
-#2.7.6 - 1/16/2004 - MAP - fixed bug with StringIO importing
-#3.0b3 - 1/23/2004 - MAP - parse entire feed with real XML parser (if available);
-# added several new supported namespaces; fixed bug tracking naked markup in
-# description; added support for enclosure; added support for source; re-added
-# support for cloud which got dropped somehow; added support for expirationDate
-#3.0b4 - 1/26/2004 - MAP - fixed xml:lang inheritance; fixed multiple bugs tracking
-# xml:base URI, one for documents that don't define one explicitly and one for
-# documents that define an outer and an inner xml:base that goes out of scope
-# before the end of the document
-#3.0b5 - 1/26/2004 - MAP - fixed bug parsing multiple links at feed level
-#3.0b6 - 1/27/2004 - MAP - added feed type and version detection, result['version']
-# will be one of SUPPORTED_VERSIONS.keys() or empty string if unrecognized;
-# added support for creativeCommons:license and cc:license; added support for
-# full Atom content model in title, tagline, info, copyright, summary; fixed bug
-# with gzip encoding (not always telling server we support it when we do)
-#3.0b7 - 1/28/2004 - MAP - support Atom-style author element in author_detail
-# (dictionary of 'name', 'url', 'email'); map author to author_detail if author

-# dangerous markup; fiddled with decodeEntities (not right); liberalized
-# date parsing even further
-#3.0b12 - 2/6/2004 - MAP - fiddled with decodeEntities (still not right);
-# added support to Atom 0.2 subtitle; added support for Atom content model
-# in copyright; better sanitizing of dangerous HTML elements with end tags
-# (script, frameset)
-#3.0b13 - 2/8/2004 - MAP - better handling of empty HTML tags (br, hr, img,
-# etc.) in embedded markup, in either HTML or XHTML form (<br>, <br/>, <br />)
-#3.0b14 - 2/8/2004 - MAP - fixed CDATA handling in non-wellformed feeds under

-# (MarkMoraes); support for textinput/textInput
-#3.0b20 - 4/7/2004 - MAP - added CDF support
-#3.0b21 - 4/14/2004 - MAP - added Hot RSS support
-#3.0b22 - 4/19/2004 - MAP - changed 'channel' to 'feed', 'item' to 'entries' in
-# results dict; changed results dict to allow getting values with results.key
-# as well as results[key]; work around embedded illformed HTML with half
-# a DOCTYPE; work around malformed Content-Type header; if character encoding
-# is wrong, try several common ones before falling back to regexes (if this
-# works, bozo_exception is set to CharacterEncodingOverride); fixed character

-# from Unicode to raw strings before feeding data to sgmllib.SGMLParser;
-# convert each value in results to Unicode (if possible), even if using
-# regex-based parsing
-#3.0b23 - 4/21/2004 - MAP - fixed UnicodeDecodeError for feeds that contain
-# high-bit characters in attributes in embedded HTML in description (thanks
-# Thijs van de Vossen); moved guid, date, and date_parsed to mapped keys in

-# failed to parse utf-16 encoded feeds; made source into a FeedParserDict;
-# duplicate admin:generatorAgent/@rdf:resource in generator_detail.url;
-# added support for image; refactored parse() fallback logic to try other
-# encodings if SAX parsing fails (previously it would only try other encodings
-# if re-encoding failed); remove unichr madness in normalize_attrs now that
-# we're properly tracking encoding in and out of BaseHTMLProcessor; set
-# feed.language from root-level xml:lang; set entry.id from rdf:about;
-# send Accept header
-#3.0 - 6/21/2004 - MAP - don't try iso-8859-1 (can't distinguish between
-# iso-8859-1 and windows-1252 anyway, and most incorrectly marked feeds are

-# tried twice (even if it failed the first time)
-#3.0.1 - 6/22/2004 - MAP - default to us-ascii for all text/* content types;

-# digest auth or proxy support); add code to parse username/password
-# out of url and send as basic authentication; expose downloading-related
-# exceptions in bozo_exception (aaronsw); added __contains__ method to
-# FeedParserDict (aaronsw); added publisher_detail (aaronsw)
-#3.2 - 7/3/2004 - MAP - use cjkcodecs and iconv_codec if available; always
-# convert feed to UTF-8 before passing to XML parser; completely revamped
-# logic for determining character encoding and attempting XML parsing
-# (much faster); increased default timeout to 20 seconds; test for presence
-# of Location header on redirects; added tests for many alternate character
-# encodings; support various EBCDIC encodings; support UTF-16BE and
-# UTF16-LE with or without a BOM; support UTF-8 with a BOM; support

-# can add support for additional date formats at runtime; added support
-# for OnBlog, Nate, MSSQL, Greek, and Hungarian dates (ytrewq1); added
-# zopeCompatibilityHack() which turns FeedParserDict into a regular
-# dictionary, required for Zope compatibility, and also makes command-
-# line debugging easier because pprint module formats real dictionaries
-# better than dictionary-like objects; added NonXMLContentType exception,
-# which is stored in bozo_exception when a feed is served with a non-XML
-# media type such as 'text/plain'; respect Content-Language as default
-# language if not xml:lang is present; cloud dict is now FeedParserDict;
-# generator dict is now FeedParserDict; better tracking of xml:lang,
-# including support for xml:lang='' to unset the current language;
-# recognize RSS 1.0 feeds even when RSS 1.0 namespace is not the default
-# namespace; don't overwrite final status on redirects (scenarios:
-# redirecting to a URL that returns 304, redirecting to a URL that
-# redirects to another URL with a different type of redirect); add
-# support for HTTP 303 redirects
-#4.0 - MAP - support for relative URIs in xml:base attribute; fixed
