title: Notepad++ regex -> newLine
body: <p>I use Notepad++ and I need to delete all lines starting with, say "abc".</p>
  
  <p>Attention, I don't need to replace the line starting with "abc" with a empty line, but I need to completely delete these lines.</p>
  
  <p>How do I proceed (using regex, I suppose)?</p>
