Is possible to 2-way replace in PhpStorm or Notepad++?

I have some CSS code in my document include left and right words.

I need to replace right => left and left => right.

Is possible in PhpStorm or Notepad++ to replace these words simultaneous ?

Solution

  • Using Notepad++

    • Ctrl+H
    • Find what: (right)|(left)
    • Replace with: (?1left:right)
    • check Wrap around
    • check Regular expression
    • Replace all

    Explanation:

    (right)     # group 1
|           # OR
(left)      # group 2

    Replacement:

    (?1         # if group 1 exists
    left    # replace with left
    :       # else
    right   # replace with right
)
