title: XML Include elements from another xml
body: <p>So we have a xml file :</p>
  
  <p>EnglandCities.xml</p>
  
  <pre><code>&lt;Cities&gt;
      &lt;City Name="London"&gt;
          other children
      &lt;/City&gt;
      &lt;City Name="Southampton"&gt;
          other children
      &lt;/City&gt;
  &lt;/Cities&gt;
  </code></pre>
  
  <p>Now we need a second file say :
  UKCities.xml</p>
  
  <pre><code>&lt;Cities&gt;
      &lt;City Name="London"&gt;
          other children
      &lt;/City&gt;
      &lt;City Name="Southampton"&gt;
          other children
      &lt;/City&gt;
      &lt;City Name="Belfast"&gt;
          other children
      &lt;/City&gt;
      &lt;City Name="Edinburgh"&gt;
          other children
      &lt;/City&gt;
  &lt;/Cities&gt;
  </code></pre>
  
  <p>This UKCities.xml has new  entries "Belfast" &amp; "Edinburgh".</p>
  
  <p>Can we do a xml:include (or something similar) in UKCities.xml to get "London" &amp; "Southampton" elements from EnglandCities.xml instead of typing them in?
  Something of the sorts as below:</p>
  
  <pre><code>&lt;Cities&gt;
      &lt;xml:include file="EnglandCities.xml"/&gt;
      &lt;City Name="Belfast"&gt;
          other children
      &lt;/City&gt;
      &lt;City Name="Edinburgh"&gt;
          other children
      &lt;/City&gt;
  &lt;/Cities&gt;
  </code></pre>
