Java to read xml file

sponsored links
xml file used to package objects for client and server interaction, or as a configuration file to use, how to generate xml parsing, or it becomes very necessary. java parsing xml document commonly used in four ways: DOM, SAX, JDOM and Dom4J. In contrast, the performance of Dom4J best, hibernate all xml files using this analytic approach, SAX is event-driven use of special analytical methods, albeit inefficiently considerable, but not conducive to encoding, DOM parsing the xml form of the tree, though not as effective high, but the programmer to understand and easy to operate. In a small project before the need to read xml format configuration files, between small, it uses the most traditional way to handle DOM parsing. Review summary.
DocumentBuilderFactory domFactory = DocumentBuilderFactory
                try {
                        DocumentBuilder domBuilder = domFactory.newDocumentBuilder();
                        InputStream is = new FileInputStream(path);
                        Document dom = domBuilder.parse(is);
                        Element ement = dom.getDocumentElement();
                        NodeList nodes = ement.getChildNodes();

                        for (int i = 0; i < nodes.getLength(); i++) {
                                Node root = nodes.item(i);
                                if (root.getNodeType() == root.ELEMENT_NODE) {
                                        String name = root.getAttributes().getNamedItem("name")
                        for (Node node = root.getFirstChild(); node != null; 
node = node.getNextSibling()) {
                                                        if (node.getNodeType() == node.ELEMENT_NODE) {
                } catch (Exception e) {

As the process of the basic code, the xml as a tree, level by level traversal nodes, with a very convenient.
