Usage

From source file:XMLInfo.java

public static void main(String args[]) {

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();

        Node root = document.getDocumentElement();
        System.out.print("Here is the document's root node:");
        System.out.println(" " + root.getNodeName());
        System.out.println("Here are its child elements: ");
        NodeList childNodes = root.getChildNodes();
        Node currentNode;

        for (int i = 0; i < childNodes.getLength(); i++) {
            currentNode = childNodes.item(i);
            System.out.println(currentNode.getNodeName());
        }

        // get first child of root element
        currentNode = root.getFirstChild();

        System.out.print("The first child of root node is: ");
        System.out.println(currentNode.getNodeName());

        // get next sibling of first child
        System.out.print("whose next sibling is: ");
        currentNode = currentNode.getNextSibling();
        System.out.println(currentNode.getNodeName());

        // print value of next sibling of first child
        System.out.println("value of " + currentNode.getNodeName() + " element is: "
                + currentNode.getFirstChild().getNodeValue());

        // print name of parent of next sibling of first child
        System.out.print("Parent node of " + currentNode.getNodeName() + " is: "
                + currentNode.getParentNode().getNodeName());
    }
    // handle exception creating DocumentBuilder
    catch (ParserConfigurationException parserError) {
        System.err.println("Parser Configuration Error");
        parserError.printStackTrace();
    }

    // handle exception reading data from file
