Notepad++ regex capture groups: a=b to b=a

got some equations like

param1 = src.Name
param(2) = src.Width
param(3) = src.Name
param(1) = src.Name

and you want to change them to

src.Name = param1
src.Width = param(2)
src.Name = param(3)
src.Name = param(1)

Using Notepad++ Find and Replace: Regular Expression mode

Find ([^=\n\r])=([^=\n\r])
Replace With ${2}=${1}
