from scrapy.selector import HtmlXPathSelector 
from thehack.items import NowItem 
import time 

class MySpider(BaseSpider): 
    name = "nowhere" 
    allowed_domains = ["n0where.net"] 
    start_urls = ["https://n0where.net/"] 

    def parse(self, response): 
     for article in response.css('.loop-panel'): 
      item = NowItem() 
      item['title'] = article.css('.article-title::text').extract_first() 
      item['link'] = article.css('.loop-panel>a::attr(href)').extract_first() 
      item['body'] ='' .join(article.css('.excerpt p::text').extract()).strip() 
      #date ga kepake 
      #item['date'] = article.css('[itemprop="datePublished"]::attr(content)').extract_first() 
      yield item 
      time.sleep(5)
