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
