I dont think u could extract a data successfully from an internet webpage always. As all webpages do not allow opening of their page source. Also some webpages are not created by users rather they use web editing softwares.

I'm not quite sure what you're trying to do here. This is a collection of utilities that you would use in a Python script, not an HTML page. It's not even a complete script - there is no main function.

To use this properly, you would need to write a Python script that loads the web page, uses the utilities above to extract the various parts of the page, then does something with the result.

Perhaps you could provide a bit more detail about what you're trying to do, then we can help further.
