title: Numbers & escape characters for regex replacement in Notepad++
body: <p>I'm trying to match a pattern using RegEx in notepad++, but not having much luck. I'm able to match part but not all of it.</p>
  
  <p>I need to search for this line:</p>
  
  <pre><code>    &lt;size value="Large" pax="13074"/&gt;
  </code></pre>
  
  <p>And replace it with this:</p>
  
  <pre><code>    &lt;size value="Very_large" pax="41450"  cargo="Largest" cargovolume="3227"/&gt;
  </code></pre>
  
  <p>Essentially I need to find all patterns matching <code>pax="n"/&gt;</code> and replace them with <code>pax="n" cargo="Largest" cargovolume="0"/&gt;</code> while retaining the initial value of n.</p>
  
  <p>So, ideas anyone?</p>
