Notepad++:: Completely remove lines that contains question mark via Regex

Question

Well, I guess that that is my title is pretty much self explanatory on what I'm about to achieve.

Here is an example of my current text file:

"Diva" was the winning song of the Eurovision Song Contest 1998.
Who will win Eurovision Song Contest 2015?
Eurovision Song Contest Statistics:
Who will win Eurovision 2015?

This is what I want to get:

"Diva" was the winning song of the Eurovision Song Contest 1998.
Eurovision Song Contest Statistics:

So basically each line that contains the ? character (the location doesn't necessarily have to be at the end of the line) will be replaced with nothing.

I have tried [^\r\n]*?[^\r\n]*([\r\n]+|$) but it removes too much.

You can use [^\r\n]*\?[^\r\n]*([\r\n]+|$) regex to match a line having a ? symbol. Mark . matches newline.

Replace with empty string.

Opps... This was exactly what I was doing I just forgot the backslash \? Thank you very much ! :) – Hezi-Gangina Apr 09 '15 at 12:10
@Hezi-Gangina: You are welcome. `?` is a special character in regexes, and must be escaped when you search for a literal `?`. Just in case you are interested, here is some more information on what needs to be escaped: http://stackoverflow.com/questions/399078/what-special-characters-must-be-escaped-in-regular-expressions. – Wiktor Stribiżew Apr 09 '15 at 12:11
I also added to the question that detail that you tried a regex with unescaped question mark. It's important. – Wiktor Stribiżew Apr 09 '15 at 12:20

In order to deal with any linebreak:

Find what: ^.*\?.*(\R|$)
Replace with: <NOTHING>

\R stands for any line break, ie. \r, \n and \r\n

Make sure that Regular Expression is checked and dot matches newline is NOT.

You can avoid regular expressions and use the Mark tab of the Find window. Select Search mode as Normal, also select Bookmark line. Set the Find what to be ? and then click Mark all. Next use the menu => Search => Bookmarks => Remove bookmarked lines.
