Parsing XML using Java

The idea here is to parse the employees.xml file with content as below

<?xml version="1.0" encoding="UTF-8"?>
<Personnel>
  <Employee type="permanent">
        <Name>Seagull</Name>
        <Id>3674</Id>
        <Age>34</Age>
   </Employee>
  <Employee type="contract">
        <Name>Robin</Name>
        <Id>3675</Id>
        <Age>25</Age>
    </Employee>
  <Employee type="permanent">
        <Name>Crow</Name>
        <Id>3676</Id>
        <Age>28</Age>
    </Employee>
</Personnel>
From the parsed content create a list of Employee objects and print it to the console. The output would be something like

Employee Details - Name:Seagull, Type:permanent, Id:3674, Age:34.
Employee Details - Name:Robin, Type:contract, Id:3675, Age:25.
Employee Details - Name:Crow, Type:permanent, Id:3676, Age:28.

 // Create the Factory and Document builder

 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
 DocumentBuilder docBuilder = factory.newDocumentBuilder();

// Parse the xml document as input stream
 Document document = docBuilder.parse(new ByteArrayInputStream(responseStr.getBytes()));
 

// Read the document element or the root of the document

Element docElement = document.getDocumentElement();

//This will read the value of a given code element

String responseCode = getTextValue(docElement, "Name");

private String getTextValue(final Element element, final String tagName)
    {
        NodeList nl = element.getElementsByTagName(tagName);
        if (null != nl && nl.getLength() > 0)
        {
            Element ele = (Element) nl.item(0);
            return ele.getFirstChild().getNodeValue();
        }
        return null;
    }
