title: Convert XML file to CSV
body: <p>After having converted a messed up XML using regex, I now need to change it yet again.
  This source file</p>
  
  <pre><code>&lt;product&gt;
      &lt;sku&gt;SP00001&lt;/sku&gt;
      &lt;PID_OWNER_SellerID&gt;StoreName&lt;/PID_OWNER_SellerID&gt;
      &lt;EANCode&gt;8711983489813&lt;/EANCode&gt;
      &lt;DeliveryDays&gt;2&lt;/DeliveryDays&gt;
  &lt;/product&gt;
  </code></pre>
  
  <p>Has to become a CSV file, but like this:</p>
  
  <pre><code>sku        field                 value
  SP00001    PID_OWNER_SellerID    StoreName
  SP00001    EANCode               8711983489813
  SP00001    DeliveryDays          2
  </code></pre>
  
  <p>I take it this is outside of regex' scope and has to be done with XSL?</p>
