我只是想在搜索按钮上搜索公司名称，输入公司名称然后它会打开该公司的链接，如果存在我尝试了很多方法，总是有问题。 .new 网络抓取
我试过了：
from selenium import webdriver
driver=webdriver.Chrome("C:/Users/RoshanB/Desktop/sentiment1/chromedriver_win32/chromedriver")
driver.get("http://www.careratings.com/brief-rationale.aspx")
但现在我不知道如何点击“搜索公司名称”，输入公司名称并使用 selenium 打开该公司链接

试试这个：
from selenium import webdriver
import time
from selenium.webdriver.common.keys import Keys
from bs4 import BeautifulSoup
from bs4.element import Tag
driver = webdriver.Chrome("C:/Users/RoshanB/Desktop/sentiment1/chromedriver_win32/chromedriver")
driver.get('http://www.careratings.com/brief-rationale.aspx')
time.sleep(4)
companyArray = []
try:
search = driver.find_element_by_name('txtSearchCompany_brief')
search.send_keys("Reliance Capital Limited")
search.send_keys(Keys.RETURN)
time.sleep(4)
soup = BeautifulSoup(driver.page_source, 'lxml')
companies = soup.find("table",class_="table1")
for tag in companies.findChildren():
if isinstance(tag, Tag) and tag.name in 'a' and tag.has_attr('href'):
url_string = "http://www.careratings.com/"+tag['href'].replace (" ","%20")
""" **Open pdf file in new tab browser** """
open_pdf(url_string)
companyArray.append(tag.text)
except Exception as e:
print(e)
driver.quit()
print(companyArray)

如果要刮公司名称，需要安装BeautifulSoup包
pip install beautifulsoup4==4.7.1
地点：
txtSearchCompany_brief 是输入搜索名称
table1是搜索结果表类

在新标签页中打开 pdf 文件：
def open_pdf(url_string):
driver1 = webdriver.Chrome("C:/Users/RoshanB/Desktop/sentiment1/chromedriver_win32/chromedriver")
driver1.get(url_string)
【讨论】：
这应该对你有用，我已经尝试过使用 id 定位器：
driver.maximize_window()
driver.get("http://www.careratings.com/brief-rationale.aspx")
search_company = driver.find_element_by_id("txtSearchCompany_brief")
search_company.send_keys("Abc India Limited:")
submit_button = driver.find_element_by_id("btn_submit").click()
submit_button.click()
但是，如果公司名称不可用，您将不得不编写代码。
