title: web.config transformation and the location element
body: <p>I cannot seem to work out how you would change the following</p>
  
  <pre><code>&lt;configuration&gt;
  &lt;location path="hello123"&gt;
  &lt;.../&gt;
  &lt;/location&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>to</p>
  
  <pre><code>&lt;configuration&gt;
  &lt;location path="world321"&gt;
  &lt;.../&gt;
  &lt;/location&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>without removing the first and adding the second. Any help with this would be great.</p>
  
  <p>Thanks</p>
