title: How to add new XML element to existing NodeList?
body: <p>Suppose I have </p>
  
  <pre><code>&lt;Start&gt;  
    &lt;abc&gt;
    ...
    ..
    &lt;/abc&gt;
    &lt;qqq id = 1&gt;
    ...
    ...
    ...
    &lt;/qqq&gt;
    &lt;qqq id = 2&gt;
    ...
    ...
    ...
    &lt;/qqq&gt;
  &lt;/Start&gt;
  </code></pre>
  
  <p>Is it possible to create new element in this kind of XML so that it takes all <code>&lt;qqq&gt;</code>'s as child nodes ? </p>
  
  <p>I.e, the final XML should look like this:</p>
  
  <pre><code>&lt;Start&gt;
     &lt;abc&gt;
     ...
     ...
     &lt;/abc&gt;
     &lt;Begin name = myname&gt;
        &lt;qqq id = 1&gt;
        ...
        ...
        ...
        &lt;/qqq&gt;
        &lt;qqq id = 2&gt;
        ...
        ...
        ...
        &lt;/qqq&gt;
     &lt;/Begin&gt;
  &lt;/Start&gt;
  </code></pre>
