How to crawl multiple URLs from csv using Selenium and Scrapy - selenium

Question

I am currently trying to crawl multiple sites from https://blogabet.com/
At the moment, I have a "ursl.txt"-file which inlcudes two URLs: 1. http://sabobic.blogabet.com 2. http://dedi22.blogabet.com
The problem I have is the following: Selenium opens each of the two URLs one after the other in the same Tab. Thereby, it is just crawling the content of the second ULR in my "ursl.txt"-file twice. It is not crawling any content from the first URL.
I think there is a problem with the for-loop and how the "parse_tip"-function is called. This is my code:
import scrapy
from scrapy import Spider
from scrapy.selector import Selector
from scrapy.http import Request
from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
from time import sleep
import re
import csv
from time import sleep
class AlltipsSpider(Spider):
name = 'alltips'
allowed_domains = ['blogabet.com']
# We are not using the response parameter in this function because the start urls are not defined
# Our class Spider is searching for the function start_requests by default
# Request has to returned or yield
def start_requests(self):
self.driver = webdriver.Chrome('C:\webdrivers\chromedriver.exe')
with open("urls.txt", "rt") as f:
start_urls = [url.strip() for url in f.readlines()]
for url in start_urls:
self.driver.get(url)
self.driver.find_element_by_id('currentTab').click()
sleep(3)
self.logger.info('Sleeping for 5 sec.')
self.driver.find_element_by_xpath('//*[#id="_blog-menu"]/div[2]/div/div[2]/a[3]').click()
sleep(7)
self.logger.info('Sleeping for 7 sec.')
yield Request(url, callback=self.parse_tip)
def parse_tip(self, response):
sel = Selector(text=self.driver.page_source)
allposts = sel.xpath('//*[#class="block media _feedPick feed-pick"]')
for post in allposts:
username = post.xpath('.//div[#class="col-sm-7 col-lg-6 no-padding"]/a/#title').extract()
publish_date = post.xpath('.//*[#class="bet-age text-muted"]/text()').extract()
yield{'Username': username,
'Publish date': publish_date
}

Answer 1

Why are you doing another request yield Request(url, callback=self.parse_tip) when you already have a response from Selenium.
Just pass that response text to parse_tip and use text inside that
class AlltipsSpider(Spider):
name = 'alltips'
allowed_domains = ['blogabet.com']
def start_requests(self):
self.driver = webdriver.Chrome('C:\webdrivers\chromedriver.exe')
with open("urls.txt", "rt") as f:
start_urls = [url.strip() for url in f.readlines()]
for url in start_urls:
self.driver.get(url)
self.driver.find_element_by_id('currentTab').click()
sleep(3)
self.logger.info('Sleeping for 5 sec.')
self.driver.find_element_by_xpath('//*[#id="_blog-menu"]/div[2]/div/div[2]/a[3]').click()
sleep(7)
self.logger.info('Sleeping for 7 sec.')
for item in self.parse_tip(text= self.driver.page_source):
yield item
def parse_tip(self, text):
sel = Selector(text=text)
allposts = sel.xpath('//*[#class="block media _feedPick feed-pick"]')
for post in allposts:
username = post.xpath('.//div[#class="col-sm-7 col-lg-6 no-padding"]/a/#title').extract()
publish_date = post.xpath('.//*[#class="bet-age text-muted"]/text()').extract()
yield{'Username': username,
'Publish date': publish_date
}
