您可以使用以下代码块
<iframe>专门获取所有标签
Selenium：
from selenium import webdriverbrowser = webdriver.Firefox(executable_path=r'C:UtilityBrowserDriversgeckodriver.exe')browser.get("https://reddit.com")frames_tag = browser.find_elements_by_tag_name("iframe")frames_xpath = browser.find_elements_by_xpath("//iframe")frames_css = browser.find_elements_by_css_selector("iframe")print("frames detected through iframe tag are %s" %frames_tag)print("frames detected through xpath are %s" %frames_xpath)print("frames detected through css are %s" %frames_css)browser.quit()我的控制台上的输出是：
