title: Removing empty lines from CSV file
body: <p>I am having a CSV file in following format:</p>
  
  <pre><code>1,2,3,4,5,6,7,8,9,10
  ,,,,,,,,,
  1,2,3,4,5,6,7,8,9,10
  ,,,,,,,,,
  ,,,,,,,,,
  ,,,,,,,,,
  ,,,,,,,,,
  </code></pre>
  
  <p>And I need to remove all the empty lines from the data using notepad++.
  Once I tried to using the replace function, with following parameters:
  Find What: \r\n,+\r\n
  Replace With: \r\n</p>
  
  <p>Following result is obtained:</p>
  
  <pre><code>1,2,3,4,5,6,7,8,9,10
  1,2,3,4,5,6,7,8,9,10
  ,,,,,,,,,
  ,,,,,,,,,
  </code></pre>
  
  <p>Why is it so?
  What is wrong with regex used?
  Please advise.</p>
