Remove hyperlink properties from inside <i> etc

[mufc]

I know this:

Small piece of code to convert all links to text:

def preprocess_html(self, soup):
for alink in soup.findAll('a'):
if alink.string is not None:
tstr = alink.string
alink.replaceWith(tstr)
return soup

BUT how do you convert links to text that are hidden in 'h2', 'strong' 'i' etc

<h2>

</h2>

OR like this

I use regular expressions. If you just want to remove hyperlink properties, then it is possible to do, for example, this way:

preprocess_regexps = [
        (re.compile(r'<a.*?>'), lambda h1: ''),
        (re.compile(r'</a>'), lambda h2: '')]

<h2>
In Theaters
</h2>

If you want to preserve a link as a text, then you can do smth like this:

preprocess_regexps = [
        (re.compile(r'(<a href=")([^"]+)(">)(.*)(</a>)'), 
           lambda h: '%s (%s)' % (h.group(4), h.group(2))]

This is my the DogHouseDiaries webcomics recipe with something similar I wrote above:

Spoiler:

import time, re
from calibre.web.feeds.news import BasicNewsRecipe

class DogHouse(BasicNewsRecipe):
title = 'DOGHOUSEDIARIES'
description = 'The comic is simply a commentary on the love life of sandwiches by Ray, Raf & Will'
__author__ = 'thearr'
language = 'en'

use_embedded_content = False
oldest_article = 0
max_articles_per_feed = 4
keep_only_tags = [dict(name='div', attrs={'class':'object'}),
dict(name='div', attrs={'class':'entry'})]
remove_tags = [dict(name='div', attrs={'class':'sociable'})]
no_stylesheets = True

preprocess_regexps = [
(re.compile(r'<a.*?>'),
lambda h1: ''),
(re.compile(r'</a>'),
lambda h2: ''),
(re.compile(r'(<img.*title=")([^"]+)(".*>)'),
lambda m: '%s%s<p><i><font color="grey">%s</font></i></p>' % (m.group(1), m.group(3), m.group(2)))
]

def parse_index(self):
soup = self.index_to_soup('http://www.thedoghousediaries.com/?p=34')
book = []
for comic in soup.findAll('option'):
if comic['value'] != '0':
book.append({
'date': '2011-02-15',
'url': comic['value'],
'title': self.tag_to_string(comic),
'description': '',
'content': ''
})
return [('DOGHOUSEDIARIES', book)]
