问题描述

我正试图从

I am trying to get the text "Album Vol.1 [Every letter I sent you] LP (Normal Edition)" from http://www.ktown4u.com/iteminfo?grp_no=231307&goods_no=44363#dt_wrap01 under the description tab but I keep getting this error message.

selenium.common.exceptions.NoSuchElementException:
Message: no such element: Unable to locate element: 
{"method":"xpath","selector":".//div[@class='view_body']/div[2]/span"}

不同的版本会给我类似的错误消息.

Different variations give me similar error messages.

driver.find_element_by_css_selector('.view_body>div:nth-child(2)>span')
driver.find_element_by_xpath(".//div[@class='view_body']/div[2]/span")
driver.find_element_by_tag_name('span')

我还尝试了 driver.implicitly_wait(10)无济于事.

推荐答案

要打印文本专辑第1卷[我给您发送的每封信] LP(普通版)，您必须诱导 WebDriverWait 用于 visibility_of_element_located()可以使用以下任一定位器策略:

To print the text Album Vol.1 [Every letter I sent you] LP (Normal Edition) you 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 :

driver.get('http://www.ktown4u.com/iteminfo?grp_no=231307&goods_no=44363#dt_wrap03')
print(re.split('[*\-]',WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.payment-order-list>ul>li"))).text)[1])

使用 XPATH :

driver.get('http://www.ktown4u.com/iteminfo?grp_no=231307&goods_no=44363#dt_wrap03')
print(re.split('[*\-]',WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//div[@class='payment-order-list']/ul/li"))).text)[1])

控制台输出:

Console Output:

Album Vol.1 [Every letter I sent you] LP (Normal Edition)

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
