Issue with Recipe

raijinfolly · 10-26-2011, 10:07 PM

This recipe was working a few weeks ago, but suddenly stopped. I thought I'd figured out the issue, but it still gives the same error every time I run it.

I know just enough Python to get myself in trouble, but I'm having issues debugging this issue deep enough to figure out what the issue is.

Code:

from calibre.web.feeds.recipes import BasicNewsRecipe
from calibre.web.feeds import Feed

import re

class PaizoWebFictionRecipe(BasicNewsRecipe):
  def get_feeds(self):
    feeds = []
    soup = self.index_to_soup('http://paizo.com/store/byCompany/p/paizoPublishingLLC/pathfinder/tales/serial')
    for alink in soup.findAll("span", {"class" : "productCategory"}):
      url = alink.a
      name = '{}'.format(url.string)
      if url.string != None:
        feeds.append((name, 'http://paizo.com' + url['href'] + '&xml=atom'))
    if not feeds:
      raise NotImplementedError
    return feeds
  
  title = u'Pathfinder Web Fiction v2.0.1'
  oldest_article = 1000000
  max_articles_per_feed = 10
  reverse_article_order = True
  cover_url = 'http://paizo.com/image/content/Logos/PathfinderTales_500.jpeg'
  remove_tags_after = [dict(name='a', text='Tags')]
  preprocess_regexps = [ (re.compile(r'src="', re.DOTALL|re.IGNORECASE), lambda match: 'src="http://www.paizo.com'), ]

Here's the error code:

Figured out the issue. It was reading the title attribute of the link instead of the text within it. This caused the issue of processing things like registered trademark symbols as control codes instead of the symbols they were in the feed names.

I split out those parts and ended up with the following code:

Code:

from calibre.web.feeds.recipes import BasicNewsRecipe
from calibre.web.feeds import Feed

import re

class PaizoWebFictionRecipe(BasicNewsRecipe):
  def get_feeds(self):
    feeds = []
    soup = self.index_to_soup('http://paizo.com/pathfinder/tales/serial')
    for alink in soup.findAll("span", {"class" : "productCategory"}):
      url = alink.a
      name = '{}'.format(url.string)
      name = name.split('>').pop()
      print 'Story name is : ', name
      if url.string != None:
        feeds.append((name, 'http://paizo.com' + url['href'] + '&xml=atom'))
    if not feeds:
      raise NotImplementedError
    print 'Feeds are: ', feeds
    return feeds
  
  title = 'Pathfinder Web Fiction v2.0.1'
  oldest_article = 1000000
  max_articles_per_feed = 10
  reverse_article_order = True
  cover_url = 'http://paizo.com/image/content/Logos/PathfinderTales_500.jpeg'
  remove_tags_after = [dict(name='a', text='Tags')]
  preprocess_regexps = [ (re.compile(r'src="', re.DOTALL|re.IGNORECASE), lambda match: 'src="http://www.paizo.com'), ]

Sorry to resurrect this old thread, but I would really like to use this recipe and even I don't know much about coding...

I managed to fix one of the problems in the recipe, by changing the URL function, but now I'm running to another "All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters (Error Code: 1)"

Here's the recipe that I'm using:

Code:

from calibre.web.feeds.recipes import BasicNewsRecipe
from calibre.web.feeds import Feed

import re

class PaizoWebFictionRecipe(BasicNewsRecipe):
  def get_feeds(self):
    feeds = []
    soup = self.index_to_soup('http://paizo.com/pathfinder/tales/serial')
    for alink in soup.findAll("span", {"class" : "productCategory"}):
      url = alink.a
      name = '{}'.format(url.string)
      name = name.split('>').pop()
      print 'Story name is : ', name
      if url.string != None:
        feeds.append((name, url['href'] + '&xml=atom'))
    if not feeds:
      raise NotImplementedError
    print 'Feeds are: ', feeds
    return feeds
  
  title = 'Pathfinder Web Fiction v2.0.1'
  oldest_article = 1000000
  max_articles_per_feed = 10
  reverse_article_order = True
  cover_url = 'http://paizo.com/image/content/Logos/PathfinderTales_500.jpeg'
  remove_tags_after = [dict(name='a', text='Tags')]
  preprocess_regexps = [ (re.compile(r'src="', re.DOTALL|re.IGNORECASE), lambda match: 'src="http://www.paizo.com'), ]

Any thoughts/advice would be much appreciated - I'm trying to learn some python through this process so I can help myself more in the future, so any explanatory notes will be appreciated too! (I started reading http://oldbugs.calibre-ebook.com/wik...s:atasteofsoup but wasn't quite sure how to apply it to my specific problem...

Any thoughts? I don't really know how to read the python expression that split out the unreadable character, so if someone could point me towards another template I could use, that would be helpful too, thanks!
