The following third-party Python packages are not included in WebHelpers due to their size or dependencies, but are often used in WebHelpers applications.
A robust HTML/XML parser that can make sense of bad markup.
Clean up and pretty print HTML. This is a C library. There are several Python bindings to it.
Convert Unicode characters to ASCII equivalents. Accented letters and symbols are converted to a visual approximation, and non-Latin letters are converted to their standard Latin pronounciation. Several of the convert_\* functions in webhelpers.text will use Unidecode if it's installed.
An object-oriented alternative to the path functions in os, os.path, and shutil. Similar packages include path.py.
