PyKHTML is...

A Python module for writing website scrapers/spiders. Whereas traditional methods focus on writing the code to parse HTML/forms themselves, PyKHTML uses the excellent KHTML engine to do all the trudge work. It therefore handles webpages very well (even the severely crufty ones) and is pretty darn fast (implemented in C++). As a bonus the module handles JavaScript and cookies transparently. Hurrah!

How?

PyKHTML requires PyKDE 3 (and hence in turn PyQt 3 + KDE libs). If you would like to run PyKHTML on servers without an X display then Xvfb is required. Fortunately these requirements should come bundled with most modern Linux distributions, and support for Windows/Mac should appear in the next few months.
