使用 Python Selenium 在 click() 后提取内容

Question

我想提取一个人 Herbert W. Gullquist 的简历。在此网页点击他的名字（“Gullquist 是首席投资官和 Lazard Asset Management 的普通合伙人......”）后，它来自“经理时间线”：https://www.morningstar.com/funds/xnas/lziex/people

代码找不到那个人。是不是因为代码点错了地方？

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

options = webdriver.ChromeOptions() 
options.add_argument("start-maximized")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options)
driver.get("https://www.morningstar.com/funds/xnas/lziex/people")

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='sal-component-ctn sal-component-manager-timeline-chart']//text[text()='Gullquist']/.."))).click()
print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.sal-modal-biography.ng-binding.ng-scope"))).text.strip())

此外，如果我想要经理时间轴中每个人的简历（总共 9 人）而不是某个人怎么办？非常感谢任何帮助。

Answer 1

错误的xpath 值在该行：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='sal-component-ctn sal-component-manager-timeline-chart']//text[text()='Gullquist']/.."))).click()

使用以下值更改：

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//*[text()='Herbert W. Gullquist']"))).click()

Answer 2

有 6 位现任经理和 3 位前任经理。获取两个链接

current= driver.find_elements(By.XPATH, "//*[@class='current-manager-timeline']//*[name()='g']//*[name()='text']") past = driver.find_elements(By.XPATH, "//*[@class='past-manager-timeline']//*[name()='g']//*[name()='text']") total_links = current+past

获取链接后，您可以循环访问链接并提取生物

bio = driver.find_element(By.XPATH, "//div[contains(@class, 'biography')]").text

Answer 3

要从网页https://www.morningstar.com/funds/xnas/lziex/people 中提取“Herbert W. Gullquist”的简历并关闭弹出窗口，因为该元素位于 <tag> 标记内，您需要诱导 WebDriverWait 为element_to_be_clickable()，您可以使用以下Locator Strategies：

• 代码块：

  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_experimental_option("excludeSwitches", ["enable-automation"])
  options.add_experimental_option('useAutomationExtension', False)
  driver = webdriver.Chrome(options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get("https://www.morningstar.com/funds/xnas/lziex/people")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='sal-component-ctn sal-component-manager-timeline-chart']//*[name()='svg']//*[name()='g' and @class='past-manager-timeline']//*[text()='Herbert W. Gullquist']"))).click()
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.sal-modal-biography.ng-binding.ng-scope"))).text.strip())
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='sal-component-ctn sal-modal-scrollable']//div[@class='sal-manager-modal__modalHeader']//button[@class='sal-icons sal-icons--close mds-button mds-button--icon-only']"))).click()
  

• 控制台输出：

  Gullquist is chief investment officer and a general partner with Lazard Asset Management, his employer since 1982. Previously, he spent 12 years as general partner, managing director, and chief investment officer of Oppenheimer & Company. Prior to that, from 1970 to 1971, he served as the director of Stuyvesant Asset Management, a company he founded. He has also worked at First National Bank of Chicago.
