I need to replace 3 lines of code, each line is on a seperate line in the file. I have to replace it with 4 lines of php code, however when I copy my 3 lines into the jedit editor, it puts them all on one line and so doesnt find the lines that need changing.

It appears it can only search for a string or something to replace providing its all on one line, what about if i want to replace a block of code in 45 files like I need to now?

How do I do that?
thnx
