Ignore root element in JAXB

I am trying to parse an XML file using JAXB. My problem is I need to skip the root node. If I remove it from the xml file, I get what I need, otherwise - I get an empty object.

I'll give a simplified xml and my code (it behaves the same):

XML:

<?xml version="1.0" encoding="utf-8"?>
<Root>
<!--  <Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="Office.xsd">
-->
    <Office>
        <Employees>
            <Employee>
                <name>George</name>
                <rank>3</rank>
            </Employee>
            <Employee>
                <name>Michael</name>
                <rank>5</rank>
            </Employee>
            <Employee>
                <name>Jeff</name>
                <rank>1</rank>
            </Employee>
            <Employee>
                <name>Todd</name>
                <rank>7</rank>
            </Employee>
            <Employee>
                <name>Jessica</name>
                <rank>5</rank>
            </Employee>
        </Employees>
    </Office>
</Root>

      

        
        
        
      

    

Office class:

import javax.xml.bind.annotation.*;
import java.util.Vector;

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class Office {

   @XmlElementWrapper(name = "Employees")
   @XmlElement(name = "Employee")
   private Vector<Employee> employees;

}

      

        
        
        
      

    

Employee class:

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;

@XmlAccessorType(XmlAccessType.FIELD)
public class Employee {

   @XmlElement(name="name")
   private String name; 
   @XmlElement(name="rank")
   private int rank;


   public void promote() {
      rank++;
   }

}

      

        
        
        
      

    

Driver:

import javax.xml.stream.*; 
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.bind.Marshaller;

import java.io.FileReader;
public class Driver {

     public static void main (String[] args) {
        parseOffice();

     }

     public static void parseOffice() {
        try {

          XMLInputFactory f = XMLInputFactory.newInstance();
          XMLStreamReader reader = f.createXMLStreamReader(new FileReader("Office.xml"));

            JAXBContext context = JAXBContext.newInstance(Office.class);
            Unmarshaller unmarshaller = context.createUnmarshaller();
            Office office = unmarshaller.unmarshal(reader, Office.class).getValue();

            Marshaller marshaller = context.createMarshaller();
          marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
          marshaller.marshal(office, System.out);

         } 
         catch (Exception e) {
             e.printStackTrace();
         }
      }
}
