It provides methods and Pythonic idioms that make -it easy to navigate, search, and modify the tree. - -A well-formed XML/HTML document yields a well-formed data -structure. An ill-formed XML/HTML document yields a correspondingly -ill-formed data structure. If your document is only locally -well-formed, you can use this library to find and process the -well-formed part of it. - -Beautiful Soup works with Python 2.2 and up. It has no external -dependencies, but you'll have more success at converting data to UTF-8 -if you also install these three packages: - -* chardet, for auto-detecting character encodings - http://chardet.feedparser.org/ -* cjkcodecs and iconv_codec, which add more encodings to the ones supported - by stock Python. - http://cjkpython.i18n.org/ - -Beautiful Soup defines classes for two main parsing strategies: - - * BeautifulStoneSoup, for parsing XML, SGML, or your domain-specific - language that kind of looks like XML. - - * BeautifulSoup, for parsing run-of-the-mill HTML code, be it valid - or invalid. This class has web browser-like heuristics for - obtaining a sensible parse tree in the face of common HTML errors. - -Beautiful Soup also defines a class (UnicodeDammit) for autodetecting -the encoding of an HTML or XML document, and converting it to -Unicode. Much of this code is taken from Mark Pilgrim's Universal Feed Parser. - -For more than you ever wanted to know about Beautiful Soup, see the -documentation: -http://www.crummy.com/software/BeautifulSoup/documentation.html - -Here, have some legalese: - -Copyright (c) 2004-2010, Leonard Richardson - -All rights reserved. - -Redistribution and use in source and binary forms, with or without -modification, are permitted provided that the following conditions are -met: - - * Redistributions of source code must retain the above copyright - notice, this list of conditions and the following disclaimer. - - * Redistributions in binary form must reproduce the above - copyright notice, this list of conditions and the following - disclaimer in the documentation and/or other materials provided - with the distribution. - - * Neither the name of the the Beautiful Soup Consortium and All - Night Kosher Bakery nor the names of its contributors may be - used to endorse or promote products derived from this software - without specific prior written permission. - -THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS -"AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT -LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR -A PARTICULAR PURPOSE ARE DISCLAIMED.

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).
