-
- 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.
