title: How do I remove the root element of an XML document?
body: <p>I want to remove the root element from an following xml using Java:</p>
  
  <pre><code>&lt;BookRequest xsi:schemaLocation="http://test/books.xsd"&gt;
   &lt;Book&gt;
   &lt;Name&gt;abc&lt;/Name&gt;
   &lt;Author&gt;xyz&lt;/Author&gt;
   &lt;/Book&gt;
  &lt;/BookRequest&gt;
  </code></pre>
  
  <p>so that I will only have this as the final output:</p>
  
  <pre><code>&lt;Book&gt;
   &lt;Name&gt;abc&lt;/Name&gt;
   &lt;Author&gt;xyz&lt;/Author&gt;
  &lt;/Book&gt;
  </code></pre>
  
  <p>How can I do this?</p>
