i want to replace all style, dir, height, width and class with nothing so it will be removed
this is what i have tried for some of them and it worked in an online tester but didn't work in notepad++
( class=\"([^\"]*)\"){0,} (width=\"([^\"]*)\"){0,} (height=\"([^\"]*)\"){0,}

Answer 1

Try
\s*(?:style|dir|height|width|class)\s*=\s*"[^"]*"\s*
Of course this will remove texts like style="hello" wherever they may occur, also outside of tags.
It may be that Notepad++ doesn't support the \s shorthand. Try using
[ ]*(?:style|dir|height|width|class) *= *"[^"]*" *
instead and see if that works. The [ ] at the start can be replaced by a single space.

Answer 2

This should do the trick, at least for your example:
\s*(style|dir|height|width|class)="[^"]+"\s*
