I'm pleased to announce that listparser 0.17 is available for immediate download! This release features support for Python 2.4 through 3.3, Jython 2.5.2 and 2.5.3, as well as PyPy 1.8.0. The codebase runs on all of these with no modification, and should still also run on IronPython 2.6.2 (although I'm currently not able to test this).
listparser is a Python library that parses subscription lists (also called reading lists) and returns all of the feeds, subscription lists, and "opportunity" URLs that it finds. It supports OPML, RDF+FOAF, and the iGoogle exported settings format.
