title: Python: How to get audio source from html created with iSpring
body: <p>I am writing a python script with selenium to fetch audio source links from <a href="https://englishteststore.net/test/listening/short_talk/hard/test01/index.html" rel="nofollow noreferrer">here</a>. As this web page is created with <strong>iSpring</strong>, so I can't get a plain source of the HTML. When I use DevTools on Chrome, select the 'Element' panel, I can't find anything containing the audio source. But if I select the 'Network' panel, I can see the name of the audio file is <code>snd-74aa83a9f6a6f65bb407b4ffb9172e10dae2a3a3.mp3</code> whose initiator is index.html. Is there any way to get the audio source link using selenium, or anything else?</p>
