None of these suggestions are acceptable! TextFX's Ctrl+R replace plugin falls way short.
What EVERYONE wants, everyone that wants to perform a replacement of multiline blocks of text with another multiline block of text, is this...
2 large text boxes:
Find This:
This is line one
This is LIKE two
This is line TREE
Replace with This:
This is line 1
This is line 2
This is line 3
A checkbox for "All Open Documents"
And/Or...
Option for "Find-Replace in all Files of Type"
Then a GO button............
How hard could that be to create in Notepad++? It was done way back in 1998, a freeware utility called Search-Replace 98.
UPDATE:
The plugin suggested by numediaweb DOES EXACTLY what I needed! Hats off to numediaweb for the tip and standing applause for paul at phdesign!
