如何使用 Python Selenium 从 HTML DOM 打印更多链接？

Question

Html:

<div class="xxxx">
<a href="ooooo.pdf"></a>
</div>

Python 硒代码试验：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
print(wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.xxxx a"))).get_attribute('href'))

输出：

aaaaa.pdf

如何打印 ooooo.pdf 和 aaaaa.pdf？

我想打印更多链接，怎么办？

Answer 1

returns 单个 WebElement 因此仅打印第一个匹配元素的 href 属性。

解决方案

要提取所有 href 属性值，您必须归纳 WebDriverWait for visibility_of_all_elements_located() and you can use either of the following :

使用CSS_SELECTOR:

print([my_elem.get_attribute("href") for my_elem in WebDriverWait(driver, 10).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.xxxx a")))])

使用 XPATH:

print([my_elem.get_attribute("href") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='xxxx']//a")))])

备选

作为替代方案，您也可以尝试：

使用CSS_SELECTOR:

print([my_elem.get_attribute("href") for my_elem in driver.find_elements(By.CSS_SELECTOR, "div.xxxx a")])

使用 XPATH:

print([my_elem.get_attribute("href") for my_elem in driver.find_elements(By.XPATH, "//div[@class='xxxx']//a")])
