Best way of decoding xml code into Java objects?

I need to know what the best solution would be to read the following xml code and place the result into objects:

             <accountInformation>
           <customField>
              <key>businessregno</key>
              <value>12345</value>
           </customField>
           <customField>
              <key>emailaddress</key>
              <value>[email protected]</value>
           </customField>
           <customField>
              <key>idnumber</key>
              <value>8601095195084</value>
           </customField>
           <customField>
              <key>initial</key>
              <value>J</value>
           </customField>
           <customField>
              <key>lastname</key>
              <value>Boshoff</value>
           </customField>
           <customField>
              <key>licensetype</key>
              <value>07</value>
           </customField>
           <customField>
              <key>licensetypedescription</key>
              <value>Normal</value>
           </customField>
           <customField>
              <key>loaduserid</key>
              <value>12345</value>
           </customField>
           <customField>
              <key>passportno</key>
              <value>1234512345</value>
           </customField>
           <customField>
              <key>title</key>
              <value>Mr</value>
           </customField>
           <customField>
              <key>validationrefno</key>
              <value>0</value>
           </customField>
           <customField>
              <key>accountnumber</key>
              <value>608806709</value>
           </customField>
           <customField>
              <key>balance</key>
              <value>500</value>
           </customField>
           <customField>
              <key>contactno</key>
              <value>0846769478</value>
           </customField>
           <customField>
              <key>landlinecontactno</key>
              <value>0218865557</value>
           </customField>
           <customField>
              <key>physicaladdress</key>
              <value>SUITE 4,OU KOLLEGE GEBOU,STELLIES,WESTERN PROVINCE,5600,35,CHURCH STREET,</value>
           </customField>
           <customField>
              <key>validity</key>
              <value>true</value>
           </customField>
        </accountInformation>

The problem I have tried a hash map, but all the elements have the same name so I have a issue populating it into a list.

What would be the best way for me to write it into java objects?

Thank you for the help.

I'm doing something similar and found the w3c DOM is pretty decent.

File xmlFile = new File(path);

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setFeature(
        "http://apache.org/xml/features/nonvalidating/load-external-dtd",
        false);
DocumentBuilder builder = factory.newDocumentBuilder();

document = builder.parse(xmlFile); //or parse the String

document.getDocumentElement().normalize();

So now you have the xml file as a Document object.

Map<String, String> map = new HashMap<String, String>();
NodeList nodelist = document.getElementsByTagName("customField")

for (int i=0; i<nodelist.getLength(); i++) {
    Element element = (Element) nodelist.item(i);

    String key = element.getAttributes("key");
    String value = element.getAttributes("value");

    map.put(key,value);
}

And now you have a map of key/values.

If you are working on spring create bean for org.springframework.oxm.jaxb.Jaxb2Marshaller by setting property classesToBeBound to pojo class.
