Are you asking about how to find commented lines using your editor? Which one? — Tim Pietzcker

Thank you for responding. Question is about finding in the editor itself, using Xcode,s find and replace. — Souandios

Search for:

^(?://.*\n?)+

and replace all with nothing.

This will find all lines that start with //.

yes, you are right Tim. Could you suggest me what should i do if i want to find each such block as shown in my question which contains three commented lines, at once. Thank you.

It should be matching the entire block at once. Isn't it doing that?

Souandios Over a year ago

It is currently matching each line separately. In my case i should search all three lines as in my question at a time, for uniqueness. It aslo helps in replacing such blocks. Each result should be a block containing three commented lines.

Try ^(?://.*\n){3} - does this work? I don't own a Mac, so I can't test this myself.

Tried it. Not working. I also tried by removing '^' and again by pasting the expression three times but no luck. I dont know why but, whenever i try to match something which presides a newline character, it wont work and my be number of occurrence '{}' is also not working.
