Answer 1

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder(); 
    InputSource is = new InputSource(); 
    is.setCharacterStream(new StringReader(xmlRecords)); 

    Document doc = db.parse(is); 
    NodeList nodes = doc.getElementsByTagName("employee"); 

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

     NodeList name = element.getElementsByTagName("name"); 
     Element line = (Element) name.item(0); 
     System.out.println("Name: " + getCharacterDataFromElement(line)); 

     NodeList title = element.getElementsByTagName("title"); 
     line = (Element) title.item(0); 
     System.out.println("Title: " + getCharacterDataFromElement(line)); 
    } 

    } 

    public static String getCharacterDataFromElement(Element e) { 
    Node child = e.getFirstChild(); 
    if (child instanceof CharacterData) { 
     CharacterData cd = (CharacterData) child; 
     return cd.getData(); 
    } 
    return ""; 
    } 
}
