我只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，但总是有问题。.new 网页抓取

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)
