validate html form with powershell

How can I validate this form with a powershell script into internet explorer? https://idsapp.ulb.ac.be/pam/开发者_如何学Pythonpamnetid.php

If your intention is to validate data in HTML forms before submitting data to the server you need javascript. Powershell for form validation does not make any sense. The only validation you can obtain is on the user input for example, but nothing to do with forms submission.
