            File xmlFile = new File("...\\myXML.xml");
            DocumentBuilderFactory documentFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder documentBuild = documentFactory.newDocumentBuilder();
            Document documentUsage = documentBuild.parse(xmlFile);
            documentUsage.getDocumentElement().normalize();
            System.out.println( documentUsage.getDocumentElement().getNodeName());
            NodeList serverNode = documentUsage.getElementsByTagName("myTag");

Yes, there is. The following methods are for accessing single nodes:org.w3c.dom.Node.getFirstChild()
org.w3c.dom.Node.getLastChild()
org.w3c.dom.Node.getNextSibling()
org.w3c.dom.Node.getPreviousSibling()
org.w3c.dom.Node.getParentNode()
org.w3c.dom.Document.getDocumentElement()Notes:
1. I have only collected the most frequently used methods, so the above list is not complete. For more information consult the online API docs and tutorials.
2. These methods are useful when you query the data of XML documents that have a fixed structure. When the structure varies, you had better use NodeList because you may not know in advance the position or the number of occurrences of the node you are looking for.
