Spider): name = ' Jobbole ' allowed_domains = [' blog.jobbole.com '] start_urls = [' http://blog.jobbole.com/113 549/'] def parse (self, Response): # title = Response.xpath ('//p[@class = ' Entry-header ']/h1/text () '). Extract () [0] # create_date = Response.xpath ("//p[@class = ' entry-meta-hide-on-mobile ']/text ()"). Extract () [0].strip (). Rep Lace ("•", ""). Strip () # praise_numbers = Response.xpath ("//span[contains (@class, ' vote-post-up ')]/h10/text ()"). Extr Act () [0] # fav_nums = Response.xpath ("//span[contains (@class, ' bookmark-btn ')]/text ()"). Extract () [0] # MA Tch_re = Re.match (". *?"

Extract () [0].strip (). replace (" • "," "). Strip () Praise_numbers = Response.css (". vote-post-up h10::text "). Extract () [0] fav_nums = response.css ("Span.bookmark-btn::text").
