从特定 web 页面打印表值

Question

我想从表中提取并打印特定月份的所有条目

import os
from webdriver_manager.chrome import ChromeDriverManager
import time

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

options = Options()
options.add_argument('--ignore-certificate-errors')
options.add_argument('--start-maximized')
options.page_load_strategy = 'eager'

driver = webdriver.Chrome(options=options)

wait = WebDriverWait(driver, 20)   
driver.get("https://www.sebi.gov.in/sebiweb/home/HomeAction.do?doListing=yes&sid=3&ssid=22&smid=18")

month = "Apr"
year = "2021"

如何打印表中与特定月份和年份匹配的所有值？

Answer 1

你可以尝试这样的事情：

driver = webdriver.Chrome()
driver.get('https://www.sebi.gov.in/sebiweb/home/HomeAction.do?doListing=yes&sid=3&ssid=22&smid=18')

month = "Apr"
year = "2021"

for row in driver.find_elements_by_xpath("//table/tbody/tr/td[1]"):
    if month in row.text and year in row.text:
        x = row.find_element_by_xpath("./following-sibling::td")
        print(row.text, " ", x.text)

当然，这只会在第一页上得到结果，如果您想要更多，则需要合并分页。

Answer 2

首先在过滤器中设置日期范围。 然后使用data = driver.page_source获取页面源

接下来，使用bs4解析您的数据， soup = BeautifulSoup(data) Next loop through for row in soup.select('div.table-scrollable tbody tr') ， date = row.select('td')[0]和title = row.select('td')[1]

快乐编码。
