如何使用Selenium和Python从文本节点检索部分文本 [英] How to retrieve partial text from a text node using Selenium and Python

我只希望不使用.split()或索引切片来获取"text ..."

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

      <strong> something~ </strong>
    </a>

推荐答案

要打印文本... ，您必须诱使定位器策略:

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
