我需要一个图片 URL 列表（之后我将下载它）我不知道如何从类中提取元素并从元素中提取 URL

driver.get("https://pixabay.com/en/photos/search/" + tag +"/?orientation=horizontal&size=medium")
images = [my_elem.get_attribute("href") for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='item']/a")))] 
print("Images on Pixabay were found")

        
for x in images:
    images = driver.find_element(By.XPATH,"/html/body/div[1]/div[2]/div/div[1]/div/div[1]/div/a[1]")
    images = images.get_attribute("href")
    print(images)
    driver.get(images)
    #this is important because if I did not open a URL(Url after open is change to another.) it did not work
    sec_url = driver.current_url
    print( "Sec URL:  " +sec_url)

图像是所有 ＆lt; href＆gt; 属性的

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

列表是否在列表中迭代为：

for x in images:

您需要避免使用相同的变量名称识别元素并存储＆lt; href＆gt;属性。因此，您需要修改循环的如下：

for x in images:
    element = driver.find_element(By.XPATH,"/html/body/div[1]/div[2]/div/div[1]/div/div[1]/div/a[1]")
    element_href = element.get_attribute("href")
    print(element_href)
    driver.get(element_href)
    sec_url = driver.current_url
    print( "Sec URL:  " +sec_url)

images is a list of all the <href> attributes which you have collected using:

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

Moving ahead as you are iterating through the list as:

for x in images:

you need to avoid using the same variable name to identify an element and to store the <href> attribute within the loop. So you need to modify the for loop as follows:

for x in images:
    element = driver.find_element(By.XPATH,"/html/body/div[1]/div[2]/div/div[1]/div/div[1]/div/a[1]")
    element_href = element.get_attribute("href")
    print(element_href)
    driver.get(element_href)
    sec_url = driver.current_url
    print( "Sec URL:  " +sec_url)
