Pynzb is a unified API for parsing NZB files, with several concrete implementations included.

NZB is an XML-based file format for retrieving posts from NNTP (Usenet) servers. Since NZB is XML-based, it's relatively easy to build one-off parsers to parse NZB files. This project is an attempt to consolidate those many one-off NZB parsers into one simple interface.

This package includes three implementations (listed in order of compatibility): one based on expat, another based on ElementTree, and a final implementation based on lxml. The expat version should work on all versions of Python > 2.0. The ElementTree implementation will work on Python > 2.5. The lxml version will work as long as lxml is installed.

Simply import nzb_parser from the pynzb package. It's an instantiated version of the fastest available parser that your system can support.
