title: Can I use variables in XML files?
body: <p>Is it possible to define variables in an XML file?</p>
  <p>For example:</p>
  <p><code>VARIABLE = 'CHIEF_NAME'</code></p>
  <pre class="lang-xml prettyprint-override"><code>    &lt;foods&gt;
        &lt;food&gt;
          &lt;name&gt;French Toast&lt;/name&gt;
          &lt;price&gt;$4.50&lt;/price&gt;
          &lt;calories&gt;600&lt;/calories&gt;
          &lt;chief&gt;VARIABLE&lt;/chief&gt;
        &lt;/food&gt;
        &lt;food&gt;
          &lt;name&gt;Homestyle Breakfast&lt;/name&gt;
          &lt;price&gt;$6.95&lt;/price&gt;
          &lt;calories&gt;950&lt;/calories&gt;
          &lt;chief&gt;VARIABLE&lt;/chief&gt;
        &lt;/food&gt;
      &lt;/foods&gt;
  </code></pre>
