body: <p>I need to transform XML using xslt.</p>
  
  <p>i want to transform a node that has child nodes, to node that his tag name 
  is the name of the parent and his value is the value of one of his children.</p>
  
  <p>example:</p>
  
  <p>the given xml:</p>
  
  <pre><code>&lt;Parent&gt;
    &lt;ChildA&gt;1&lt;/ChildA&gt;
    &lt;ChildB&gt;2&lt;/ChildB&gt;
  &lt;/Parent&gt;
  </code></pre>
  
  <p>the desired xml output:</p>
  
  <pre><code>&lt;Parent&gt;2&lt;/Parent&gt;
  </code></pre>
