Yapps (Yet Another Python Parser System) is an easy to use parser generator that is written in Python and generates Python code. There are several parser generator systems already available for Python, including PyLR, kjParsing, PyBison, and mcf.pars, but I had different goals for my parser. Yapps is simple, is easy to use, and produces human-readable parsers. It is not fast, powerful, or particularly flexible. Yapps is designed to be used when regular expressions are not enough and other parser systems are too much: situations where you may write your own recursive descent parser.
Everyone's got their data in XML these days. You need to read it. You've looked at the other XML APIs and they all contain miles of crud that's only necessary when parsing the most arcane documents. Wouldn't it be nice to have an easy-to-use API for the normal XML documents you deal with? That's xmltramp:
a publish/subscribe and point to point 100% Java based MOM server (message-oriented middleware) which exchanges messages between publishers and subscribers. The message is described with XML-encoded meta information. Messages may contain everything, GIF i
an extensible HTML/XML generator written in Python. XIST is also a DOM parser (built on top of SAX2) with a very simple and pythonesque tree API. Every XML element type corresponds to a Python class and these Python classes provide a conversion method to
