No need for all that complication since guardian feeds contain complete text of every article:

class Guardian_uk(BasicNewsRecipe):
    title                 = 'The Guardian'
    oldest_article        = 2
    max_articles_per_feed = 100
    no_stylesheets        = True
    use_embedded_content  = True
    encoding              = 'utf-8'
    language              = _('English')
    
    feeds              = [(u'News: Main Section', u'http://www.guardian.co.uk/theguardian/mainsection/rss')]

    remove_tags        = [dict(name='div', attrs={'class':['related','guRssAdvert','terms']})]

Just add more feeds you need
