Python Selenium 属性值

Question

我需要名称为“serial”的属性值，但我在 python 和 selenium 方面的技能有限，无法获得该值。我正在寻找“0000013”的输出。并请指导我如何在循环中捕获元素。非常感谢。

我尝试过的：

for data in soup.find_all(class_='CoreData'):
    h = data.find('h2')
    k = h.find('serial')
    print(k)

它returns值是“None”而不是“Serial”的值

<h2>                        <!--For Verified item-->
                                        <a class="clickable" style="cursor:pointer;" onmousedown="open_item_detail('0000013', '0', false)" id="View item Detail" serial="0000013">
                                            Sample Item
                                        </a>
                                    <!--For unverified item-->
                                </h2>

Answer 1

要获取 serial 的值，请尝试以下操作：

from bs4 import BeautifulSoup

html = """
<h2>
 <!--For Verified item-->
 <a class="clickable" id="View item Detail" onmousedown="open_item_detail('0000013', '0', false)" serial="0000013" style="cursor:pointer;">
  Sample Item
 </a>
 <!--For unverified item-->
</h2>"""

soup = BeautifulSoup(html, "html.parser")

for data in soup.find_all("a", class_="clickable"):
    print(data["serial"])

输出：

要打印属性 serial 的值，即 0000013，您需要引入 for the visibility_of_element_located() and you can use either of the following :

使用CSS_SELECTOR:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "h2 a.clickable[onmousedown^='open_item_detail']"))).get_attribute("data-clipboard-text"))

使用XPATH:

print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h2//a[@class='clickable' and starts-with(@onmousedown, 'open_item_detail')]"))).get_attribute("serial"))

注意：您必须添加以下导入：

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