"scrape easy" is an extension for the python web scraping framework scrapy. The aim of this package is to cut down on the amount of code needed to create simple spiders with scrapy.
###Installation:
pip install scrapyz
For scraping items off a single page:
class RedditSpider(GenericSpider):
name = "reddit"
start_urls = ["https://www.reddit.com/"]
class Meta:
items = CssTarget("items", ".thing")
targets = [
CssTarget("rank", ".rank::text"),
CssTarget("upvoted", ".upvoted::text"),
CssTarget("dislikes", ".dislikes::text"),
CssTarget("likes", ".likes::text"),
CssTarget("title", "a.title::text"),
CssTarget("domain", ".domain > a::text"),
CssTarget("datetime", ".tagline > time::attr(datetime)"),
CssTarget("author", ".tagline > .author::text"),
CssTarget("subreddit", ".tagline > .subreddit::text"),
CssTarget("comments", ".comments::text")
]For scraping data off of an index page, following a link and collecting data off of a details page:
class RedditSpider2(IndexDetailSpider):
name = "reddit2"
start_urls = ["https://www.reddit.com/"]
class Meta:
detail_path = [CssTarget("detail_path", ".title > a::attr(href)", [absolute_url])]
detail_targets = [
CssTarget("content", ".usertext-body > div > p::text", [join]),
]
items = CssTarget("items", ".thing")
targets = [
CssTarget("rank", ".rank::text"),
CssTarget("upvoted", ".upvoted::text"),
CssTarget("dislikes", ".dislikes::text"),
CssTarget("likes", ".likes::text"),
CssTarget("title", "a.title::text"),
CssTarget("domain", ".domain > a::text"),
CssTarget("datetime", ".tagline > time::attr(datetime)"),
CssTarget("author", ".tagline > .author::text"),
CssTarget("subreddit", ".tagline > .subreddit::text"),
CssTarget("comments", ".comments::text")
]pipelines:
class RedditSpider(GenericSpider):
name = "reddit"
start_urls = ["https://www.reddit.com/"]
pipelines = [scrapyz.pipelines.RequiredFields]
class Meta:
items = CssTarget("items", ".thing")
required_fields = ["rank", "author", "domain", "comments"]
targets = [
CssTarget("rank", ".rank::text"),
CssTarget("upvoted", ".upvoted::text"),
CssTarget("dislikes", ".dislikes::text"),
CssTarget("likes", ".likes::text"),
CssTarget("title", "a.title::text"),
CssTarget("domain", ".domain > a::text"),
CssTarget("datetime", ".tagline > time::attr(datetime)"),
CssTarget("author", ".tagline > .author::text"),
CssTarget("subreddit", ".tagline > .subreddit::text"),
CssTarget("comments", ".comments::text")
]To include all scrapyz pipelines to your project add this to the bottom of your project's settings.py:
ITEM_PIPELINES.update(pipelines.get_scrapyz_pipelines())
note: scrapyz pipelines will only execute if you include a field called pipelines in your spider and the appropriate meta fields. Documentation for this might come later. For now use the code and comments. Contribution
