You can use a DOM XML parser to create an XML file using Java. A good example can be found on this site:

try {     DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();     DocumentBuilder docBuilder = docFactory.newDocumentBuilder();      //root elements     Document doc = docBuilder.newDocument();      Element rootElement = doc.createElement("company");     doc.appendChild(rootElement);      //staff elements     Element staff = doc.createElement("Staff");     rootElement.appendChild(staff);      //set attribute to staff element     Attr attr = doc.createAttribute("id");     attr.setValue("1");     staff.setAttributeNode(attr);      //shorten way     //staff.setAttribute("id", "1");      //firstname elements     Element firstname = doc.createElement("firstname");     firstname.appendChild(doc.createTextNode("yong"));     staff.appendChild(firstname);      //lastname elements     Element lastname = doc.createElement("lastname");     lastname.appendChild(doc.createTextNode("mook kim"));     staff.appendChild(lastname);      //nickname elements     Element nickname = doc.createElement("nickname");     nickname.appendChild(doc.createTextNode("mkyong"));     staff.appendChild(nickname);      //salary elements     Element salary = doc.createElement("salary");     salary.appendChild(doc.createTextNode("100000"));     staff.appendChild(salary);      //write the content into xml file     TransformerFactory transformerFactory =  TransformerFactory.newInstance();     Transformer transformer = transformerFactory.newTransformer();     DOMSource source = new DOMSource(doc);      StreamResult result =  new StreamResult(new File("C:\\testing.xml"));     transformer.transform(source, result);      System.out.println("Done");  }catch(ParserConfigurationException pce){     pce.printStackTrace(); }catch(TransformerException tfe){     tfe.printStackTrace(); }

You can use Xembly, a small open source library that makes this XML creating process much more intuitive:

String xml = new Xembler(   new Directives()     .add("root")     .add("order")     .attr("id", "553")     .set("$140.00") ).xml(); 

Xembly is a wrapper around native Java DOM, and is a very lightweight library.
