When you need to find and replace multiple lines in Notepad++, you must select Extended as search mode on the replace menu.

replace

 

For example, to replace the lines below : 

//replaces these lines with new lines
new line 1
new line 2

//new lines
new line 1
new line 2

 

Find what: my test line 1\r\nmy test line 2

Replace with: new line 1\r\nnew line 2

 

 

This method comes in very handy when you need to modify multiple lines in an xml file with thousands of lines in it.

In Notepad++ and other good editors like SublimeText or JetBrains (pycharm clion intelliJ) i recommend using regular expressions.

 Not only you can change everything you need, but search might be used as a variable (match group). So you can do everything, like swap columns in CSV, change standard of some numbers (serials with "-" between groups etc.)

This is page about regular expressions.

Regular Expression Reference: Capturing Groups and Backreferences (regular-expressions.info)

Discovering Regex in text editing is like discovering quantum physics - small interesting effect which evolved to brand new world 😉

Example:

If you have 

4-5-6 and want to achieve 654 (rearranging and concatenate digits) just type:

search : (\d)-(\d)-(\d)

replace with: \3\2\1 

I was shocked when I learned using regex. it should be taught in primary school.

If you have a problem with Regex, I will be happy to help.

@mirek-boniewicz +1 on learning regex. After I learned it, I discovered so many usages for it. I never imagined that I could use this skill so often :D.
