In Notepad++ open the window where you can search and replace something, tick the last radio button from the search mode group in the bottom left corner ("Regular expressions") and use the search and replace strings from below.
Search string:
Code:
Name="(.*?)" LocalizedName="(.*?)"
Replacement string:
Code:
Name="$2" LocalizedName="$2"
Looks like this:
Then click on "Replace all".
That should do the trick.
