quasilxml -- an lxml API compatible pure-python XML library

The goal of this library is to provide some API compatibility with the lxml library using pure Python only.

The original motivation for creating this library was to try out a largish Django project in PyPy 1.7. Unfortunately some parts of the project depended heavily on the XPath functionality in lxml. The easiest work-around was to use the pure Python py-dom-xpath library and build a compatibility layer on top of it.

Status

Currently the library doesn't implement any real functionality but only provides some empty modules and dummy classes to prevent import failures in the Django project on PyPy.

Beginnings for really bare-bones implementations of the Element class and the fromstring function are provided.
