Do you want to "view" or "edit"? You can do all sort of replacements using regular expressions. That is "edit". If you just want to view your changes, you can, of course, edit the file, and then close EmEditor without saving the file. In this way, you are not going to modify the original file, but you can still hide unimportant parts of the file.

To show you how to replace text using regular expressions, please show me an example file and how you want to change it to. Please let me know if you have further questions. Thanks!
