<p>你已经清楚地观察到有<code>3 divisions</code>、<code>Top Window</code>和<code>2 frames</code>，因此我们可以得到<code>Top Window</code>的<code>page source</code>，然后穿过<code>2 frames</code>来刮取<code>page source</code>，如下所示：</p>
<pre><code>from selenium import webdriver
driver = webdriver.Ie(r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get(r'https://www-nass.nhtsa.dot.gov/nass/cds/CaseForm.aspx?xsl=main.xsl&CaseID=773013618')
content = driver.page_source
print("Content on Top Window is :")
print(content)
multiple_frames = driver.find_elements_by_xpath('//iframe')
print("There are " +str(len(multiple_frames)) +" frames")
for frame_name in multiple_frames:
print("Content on "+frame_name.get_attribute("name")+" frame is : ")
driver.switch_to.frame(frame_name)
sub_content = driver.page_source
print(sub_content)
driver.switch_to.default_content()
driver.quit()
</code></pre>
<p>控制台上的输出是：</p>
<pre><code>Content on Top Window is :
