问题描述

我只想获取文本..."而不使用 .split() 或索引切片

I want to get only " text ... " not using .split() or index slicing

HTML:

<a class="call_recipe" href="/recipes/2913">
      " text ... "
      <strong> something~ </strong>
    </a>

HTML 快照:

解决方案

要打印 text ... 你必须诱导 WebDriverWait 用于 visibility_of_element_located() 并且您可以使用以下任一 定位器策略:

To print text ... you have to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:

  • 使用 CSS_SELECTOR、childNodes 和 strip():

print(driver.execute_script('return arguments[0].firstChild.textContent;', WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "a.call_recipe[href^='/recipes']")))).strip())

  • 使用 XPATH、get_attribute() 和 splitlines():

    print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//a[@class='call_recipe' and starts-with(@href, '/recipes')]"))).get_attribute("innerHTML").splitlines()[1])

  • 注意:您必须添加以下导入:

  • Note : You have to add the following imports :

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