#Python download html file from url driver
This tutorial aims to teach you guys on how to use the selenium web driver and do simple tasks like downloading dynamically loaded content in a website using python. A better method would be to write a small script that automates this process. In this case, the plugins or extensions, might work but it takes a long time to manually download each file. Now the thing is, lets say you want to download an entire set of videos that are loaded using different AJAX calls. One way is to use a plugin or extension for the browser like Grab Any Media or FlashGot which can handle such requests and might allow you to download it. Well, there are different ways to download them. Now the question is, how would you download such files to your computer? Another problem is that, there are still some javascript functions that need to be executed and until then, the video url does not get generated in the site. Even if you use command line tool like wget or youtube-dl, it might be possible but for some reason it just doesn’t work. You want to save this but unfortunately you couldn’t do so by right-clicking on it and saving it as the player doesn’t show that option. A scenario would be like, for example, you visited a web page and a video is loaded through a video player like jwplayer after 1 or 2 secs. This is basically done using AJAX calls or sessions where the URLs for these files are generated in some way for which you can not save them by normal means.
When you surf online, you occasionally visit websites that show content like videos or audio files which are dynamically loaded.
