Dark Keeper

Dark Keeper is open source simple web-parser for podcast-sites. Also you can use it for any sites.
Goal idea: parsing full information per each podcast episodes like number, description and download link.

Features

• simple web-spider walking on site
• cache for all downloaded pages
• parse any information from pages
• export parsed data to MongoDB

Quick start

$ mkvirtualenv keeper
(keeper)$ pip install dark-keeper
(keeper)$ cat app.py

from dark_keeper import BaseParser, DarkKeeper
from dark_keeper.exports import ExportMongo
from dark_keeper.http import HttpClient
from dark_keeper.storages import UrlsStorage, DataStorage


class PodcastParser(BaseParser):
    def parse_urls(self, content):
        urls = content.parse_urls('.posts-list > .container-fluid .text-left a')

        return urls

    def parse_data(self, content):
        data = []
        for post_item in content.get_block_items('.posts-list .posts-list-item'):
            post_data = dict(
                title=post_item.parse_text('.number-title'),
                desc=post_item.parse_text('.post-podcast-content'),
                mp3=post_item.parse_attr('.post-podcast-content audio', 'src'),
            )

            if post_data['title'] and post_data['mp3']:
                data.append(post_data)

        return data
