Print friendly url unrelated to regular url (and javascript)

[sleepless]

The url of the print friendly version is not contained anywhere in the url of the article. Instead the print-friendly url looks like: http://url.com/article_print.html?id=94148

Now there is an id tag in the original article but how do I extract that id tag and then direct calibre to the new url that contains this id?

I tried using br.follow_link and url_regex but the link to the print friendly page is actually javascript and it apparently it does not work with javascript.

(I am also very new to python)

Any help would be appreciated. This is my first post and I tried to find the answer in the forums but could not. If it has been posted many times already I apologize.

If you are interested here is the link to my feed:

and here is an article:

http://www.christianitytoday.com/ct/...isability.html

and here is that article's print friendly page:

http://www.christianitytoday.com/ct/....html?id=94467

I don't know if there's a better way to do this but it seems to work

    def print_version(self, url):
        soup = self.index_to_soup(url)
        regex = re.compile(r'javascript:printPage\((\d+?)\)',re.I)
        atag = soup.find('a',attrs={'href':regex})
        if atag is not None:
            m = regex.search(atag['href'])
            if m:
                url = 'http://www.christianitytoday.com/ct/article_print.html?id='+m.group(1)
        return url

this load the original page and find the article id by parsing the file

Note: add

import re

to the start of your recipe

That is a perfectly correct way to do it

Wow. That works perfectly. Thanks so much. I definitely could not have thought of that. Really thanks a lot.
