    <p>I am writing some data to an XML file.</p> <p>Here is the code:</p> <pre><code> 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("file.xml")); // Output to console for testing // StreamResult result = new StreamResult(System.out); transformer.transform(source, result); System.out.println("File saved!"); } catch (ParserConfigurationException pce) { pce.printStackTrace(); } catch (TransformerException tfe) { tfe.printStackTrace(); } } </code></pre> <p>This code writes the XML data to the "file.xml". If I already have a "file.xml" file, what is the best way to append the XML data to the file? Will I need to rewrite the whole above code, or is it easy to adapt the code? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
