title: How to remove "Certain" (not all) empty lines, or two consequent empty lines in notepad++
body: <p>I know that there is a way to remove empty lines in the Notepad++ through the "Edit > Line Operation"; however, it either removes ALL empty lines (in case where the empty line is not containing any characters), OR it removes only empty lines containing no characters including a space character.</p>
  
  <p>My goal is to choose which "empty line"s to be deleted. (For example, to delete those double empty lines where two consequent lines are empty; not those single empty lines. I need keep those single empty lines)</p>
  
  <p>Super ideal is to combine this operation after-which one more lines containing a specific "String" is deleted through the .<em>String.</em> Search in "Regexp" mode.</p>
  
  <p>Example:
  </p>
  
  <pre><code>&lt;/section&gt;
    &lt;!--One line empty line --&gt;
    &lt;section id="phone-number"&gt;
  
      &lt;parts level="1"&gt;
        &lt;part choice="NPXMA" name="NPXMA" desc_en="Phone Number - COUNTRY" desc_fr="Numéro de Téléphone - COUNTRY" costRetail="X.XX" costWholesale="4.50" period="monthly" applyCommission="true" visibleAtSignup="true" visibleAtPlanChange="true" /&gt;
  
        &lt;part choice="NSCA00" name="NPXMA" desc_en="Phone Number Setup Fee" desc_fr="frais d'activation de numéro" costRetail="X.XX" costWholesale="X.XX" period="once" applyCommission="false" visibleAtSignup="true" visibleAtPlanChange="true" /&gt;
  
  
        &lt;part choice="NPXMA" name="NPXMA" desc_en="Phone Number - United States" desc_fr="Numéro de Téléphone - États-Unis" costRetail="X.XX" costWholesale="X.XX" period="monthly" applyCommission="true" visibleAtSignup="true" visibleAtPlanChange="true" /&gt;
  </code></pre>
