title: Get path to all XML's nodes
body: <p>I have an example XML as follows:</p>
  
  <pre><code>&lt;message&gt;
    &lt;metadata&gt; 
      &lt;msg_id&gt;1&lt;/msg_id&gt;
      &lt;client_type&gt;type1&lt;/client_type&gt;
    &lt;/metadata&gt;
    &lt;individual&gt;
      &lt;name&gt;John&lt;/name&gt;
      &lt;surname&gt;Smith&lt;/surname&gt;
        &lt;additional_information&gt;
          &lt;e_mail&gt;aaa@gmail.com&lt;/e_mail&gt;
          &lt;phone_number&gt;11110000&lt;/phone_number&gt;
        &lt;/additional_information&gt;
    &lt;/individual&gt;
  &lt;/message&gt;
  </code></pre>
  
  <p>my goal is to get output which will show me the path to every element XML like here:</p>
  
  <pre><code>/message/metadata/msg_id
  /message/metadata/client_type
  /message/individual/name
  </code></pre>
  
  <p>and so one. How can I handle this in Java? </p>
  
  <p>Thanks a lot in advance for any hints!</p>
