Hi BRGriff!!
First of all, I want to say a big "Thank you!!".
Considering your first reply, I made a new recipe (below).
Now, that new version takes around 4 minutes to fetch and create MOBI output. That is really better than first version.
So, I believe this new recipe can be usefull for all friends that are able to read in Brazilian Portuguese (not Spanish

).
The RSS source is a brazilian, well known, news portal called R7.com.
It belongs to a broadcasting corporation called "Rede Record".
Code:
import re
class PortalR7(BasicNewsRecipe):
title = 'Noticias R7'
__author__ = 'Diniz Bortolotto'
description = 'Noticias Portal R7'
oldest_article = 2
max_articles_per_feed = 20
encoding = 'utf8'
publisher = 'Rede Record'
category = 'news, Brazil'
language = 'pt_BR'
publication_type = 'newsportal'
use_embedded_content = False
no_stylesheets = True
remove_javascript = True
remove_attributes = ['style']
feeds = [
(u'Brasil', u'http://www.r7.com/data/rss/brasil.xml'),
(u'Economia', u'http://www.r7.com/data/rss/economia.xml'),
(u'Internacional', u'http://www.r7.com/data/rss/internacional.xml'),
(u'Tecnologia e Ci\xeancia', u'http://www.r7.com/data/rss/tecnologiaCiencia.xml')
]
reverse_article_order = True
keep_only_tags = [dict(name='div', attrs={'class':'materia'})]
remove_tags = [
dict(id=['espalhe', 'report-erro']),
dict(name='ul', attrs={'class':'controles'}),
dict(name='ul', attrs={'class':'relacionados'}),
dict(name='div', attrs={'class':'materia_banner'}),
dict(name='div', attrs={'class':'materia_controles'})
]
preprocess_regexps = [
(re.compile(r'<div class="materia">.*<div class="materia_cabecalho">',re.DOTALL|re.IGNORECASE),
lambda match: '<div class="materia"><div class="materia_cabecalho">')
]
What do you think about my new recipe?
