I am working on certain stock-related projects where I have had a task to scrape all data on a daily basis for the last 5 years. i.e from 2016 to date. I particularly thought of using selenium because I can use crawler and bot to scrape the data based on the date. So I used the use of button click with selenium and now I want the same data that is displayed by the selenium browser to be fed by scrappy. This is the website I am working on right now. I have written the following code inside scrappy spider.

class FloorSheetSpider(scrapy.Spider):
    name = "nepse"

    def start_requests(self):

        driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
        
     
        floorsheet_dates = ['01/03/2016','01/04/2016', up to till date '01/10/2022']

        for date in floorsheet_dates:
            driver.get(
                "https://merolagani.com/Floorsheet.aspx")

            driver.find_element(By.XPATH, "//input[@name='ctl00$ContentPlaceHolder1$txtFloorsheetDateFilter']"
                                ).send_keys(date)
            driver.find_element(By.XPATH, "(//a[@title='Search'])[3]").click()
            total_length = driver.find_element(By.XPATH,
                                               "//span[@id='ctl00_ContentPlaceHolder1_PagerControl2_litRecords']").text
            z = int((total_length.split()[-1]).replace(']', ''))    
            for data in range(z, z + 1):
                driver.find_element(By.XPATH, "(//a[@title='Page {}'])[2]".format(data)).click()
                self.url = driver.page_source
                yield Request(url=self.url, callback=self.parse)

               
    def parse(self, response, **kwargs):
        for value in response.xpath('//tbody/tr'):
            print(value.css('td::text').extract()[1])
            print("ok"*200)
