title: Updating data in a XML file in marklogic using java api
body: <p>Say I inserted XML file in MarkLogic datastore:</p>
  
  <pre><code>&lt;Providers&gt;
      &lt;Provider&gt;
          &lt;UniqueId&gt;1111&lt;/UniqueId&gt;
          &lt;name&gt;John Doe&lt;/name&gt;
          &lt;Age&gt;40&lt;/Age&gt;
          &lt;Country&gt;MN&lt;/Country&gt;
      &lt;/Provider&gt;
      &lt;Provider&gt;
          &lt;UniqueId&gt;2222&lt;/UniqueId&gt;
          &lt;name&gt;Johny Deep&lt;/name&gt;
          &lt;Age&gt;51&lt;/Age&gt;
          &lt;Country&gt;NY&lt;/Country&gt;
      &lt;/Provider&gt;
  &lt;/Providers&gt;
  </code></pre>
  
  <p>Now if I want to update the name to 'Jane Doe' where Unique Id is '1111', how can I achieve this using MarkLogic's java API?</p>
