title: how to include external XML into the XML file- how should both file look like
body: <p><strong>I'm using .NET C# XML and LINQ to Update/delete/insert my XML file.</strong></p>
  
  <p>I've got an XML file  looks like below (image1)  and I would like to inlcude just the 2nd XML file. </p>
  
  <p>The first XML file is the original file and I don't want to touch this file. So I prefer a reference to a 2nd. file (external file) so I can add/remove XML lines there in stead of the Mainf XML file.</p>
  
  <p>But how can do include or merge the 2nd XML (External file) in to the FIRST?
  I just need to the tags (see RED box) from see in RED box.</p>
  
  <pre><code>&lt;RewriterRule&gt;
     &lt;LookFor&gt;        &lt;/LookFor&gt;
     &lt;SendTo&gt;         &lt;/SendTo&gt;
  &lt;/RewriterRule&gt;
  </code></pre>
  
  <p><strong>Question:</strong> </p>
  
  <p>1- What do I need to write for code in XML file 1 so my code in XMLfile 2 (external file) is included?</p>
  
  <p>2- How should my XMLfile 2 (external file) look like?  In fact I need the tags I think, because I'm reading the XML <code>XDocument xdoc = XDocument.Load(this.Server.MapPath(path));</code>and doing some update/deletes.....</p>
