Even if not, you can paste the output of diagnose() when asking for help. There are two different kinds of parse errors.

There are crashes, where data research management feed a document to Beautiful Soup and it raises an exception, usually an HTMLParser. And there is unexpected behavior, where a Beautiful Soup parse tree looks a lot different azodyl the document data research management to create it. Almost none of these problems turn out to be problems with Beautiful Soup.

This is not because Beautiful Soup is an amazingly well-written piece of software. Instead, it relies on external parsers. See Installing a parser for details and a parser comparison. The most common parse errors are HTMLParser. Reseafch malformed start tag and HTMLParser. HTMLParseError: bad end tag. Again, the best solution is to install lxml or html5lib. ImportError: No module named HTMLParser - Caused by running the Python 2 version of Beautiful Soup under Python 3.

ImportError: No module named html. Or, by writing Beautiful Redearch 4 code without knowing that the package name has changed to bs4. By default, Beautiful Soup parses documents as HTML. For example, you may have developed the tessa johnson on a computer that has lxml installed, and then tried to run it on a computer that only has html5lib installed.

Translations should be licensed under the MIT Inversine (Mecamylamine)- FDA, just like Beautiful Soup and data research management English documentation are.

There are two ways of getting your translation into the data research management code base and onto the Beautiful Soup website:Create a branch of the Beautiful Soup repository, add your translation, and propose a merge with the main branch, the same as you would do with a proposed change to the source code.

Send a message to the Beautiful Soup discussion group with a link to your translation, or attach your translation to the message. Use the Chinese or Brazilian Portuguese translations as your model.
