It looks like this:
Code:
class AdvancedUserRecipe1295262156(BasicNewsRecipe):
title = u'kath.net'
__author__ = 'Bobus'
description = u'Katholische Nachrichten'
oldest_article = 7
language = 'de'
max_articles_per_feed = 100
no_stylesheets = True
encoding = 'iso-8859-1'
preprocess_regexps = [
(re.compile(r'A', re.DOTALL),
lambda match: 'B'),
Edit: No, by inserting into the CODE the last two lines went two spaces forward.
Edit': The missing square bracket is, in fact, there (fault at copy/paste).
