+'''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 &quot; and &apos;.  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
+#  contains name + email address
+#3.0b8 - 1/28/2004 - MAP - added support for contributor
+#3.0b9 - 1/29/2004 - MAP - fixed check for presence of dict function; added
+#  support for summary
+#3.0b10 - 1/31/2004 - MAP - incorporated ISO-8601 date parsing routines from
+#  xml.util.iso8601
+#3.0b11 - 2/2/2004 - MAP - added 'rights' to list of elements that can contain
+#  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

+#  name was in parentheses; removed ultra-problematic mxTidy support; patch to
+#  workaround crash in PyXML/expat when encountering invalid entities
+#  (MarkMoraes); support for textinput/textInput

+#  results dict; changed results dict to allow getting values with results.key
+#  as well as results[key]; work around embedded illformed HTML with half

+#  works, bozo_exception is set to CharacterEncodingOverride); fixed character
+#  encoding issues in BaseHTMLProcessor by tracking encoding and converting
+#  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

+#  my blink tag tests
+#3.0fc3 - 6/18/2004 - MAP - fixed bug in _changeEncodingDeclaration that
+#  failed to parse utf-16 encoded feeds; made source into a FeedParserDict;
+#  duplicate admin:generatorAgent/@rdf:resource in generator_detail.url;

+#  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

+#  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
