Question

from selenium import webdriver
from bs4 import BeautifulSoup

driver = webdriver.Chrome(executable_path=r'C:/Users/User/Downloads/chromedriver.exe')

url = "xxxxxxxx"
driver.get(url)
driver.find_element_by_name("username").send_keys("xxxxx")
driver.find_element_by_name("password").send_keys("xxxxx")
elem = driver.find_element_by_css_selector("form#frmMain > a:nth-child(4)")
elem.click()

html = '''<p class="value noWrap" data-bind="text: MarketValue">R 4 516 469.32</p>'''
soup = BeautifulSoup(html, 'lxml')

for p in soup.find_all('p'):
    print(p.string)

driver.quit()

非常感谢

所需的元素是一个动态元素，因此要提取元素中的文本，必须为visibility_of_element_locited()引入WebDriverWait，您可以使用以下解决方案：

使用CSS_Selector:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "p.value.noWrap[data-bind$='MarketValue']"))).get_attribute("innerHTML"))

使用XPath:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//p[@class='value noWrap' and contains(@data-bind,'MarketValue')]"))).get_attribute("innerHTML"))

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