Count Blank Rows

dataprose

Hi all,

Using Npp v7.9.5.

How do I count blank rows?

I tried Ctrl+F with Regex but I’m getting no result or incorrect result.
My RegEx pattern: ^\s*$

What else can I do to get count of blank rows

Thanks

Maybe change your regular expression to ^\s*\R ?

Here are my Count results for the license.txt file that ships with Notepad++:

The token \s means any whitespace, including newlines. With the asterisk, it means 0-or-more-as-many-as-possible. So that expression would matches consecutive newlines as a single match - so 100 blank lines in a row would count as one match.

You either want it non-greedy using ^\s*?$ or you want to match only zero-or-more horizontal spaces on a line, with ^\h*$

Yea…my advice was bad. :-(
It will count several blank lines in a row as one.
Go with the Peter solution.
