title: regex to change href link to lowercase
body: <p>I have pages with links like:</p>
  
  <pre><code>href="FileName-One-Example.html"
  </code></pre>
  
  <p>I need to a regular expression command with Notepad++ to change the case of the anything between <code>href="</code> nad the ending <code>"</code> to lowercase, and leave everything before and after it in the page as is.</p>
  
  <p>So the result is:</p>
  
  <pre><code>href="filename-one-example.html"
  </code></pre>
