title: How to modify a HTML-file in Java and save the changes
body: <p>I have to make a simple change to a HTML-Element (add and remove some attributes). The problem is that I have to go through a lot of HTML-files to do that. </p>
  
  <p>How could I automate that? Sure, there are libraries for parsing and modifying HTML, but after looking at a few of them I am getting the feeling that most don't support saving the changes to the HTML-files.</p>
