Java从xml递归读取节点只返回#text节点

Question

我正在使用这种方法从 xml 文件中读取所有节点。但似乎我的递归不起作用，因为所有节点都是 #text 节点。我怎样才能跳过它并让它返回我的实际节点？

private void iterateNodes(Node node) {

    System.out.println("Node: " + node.getNodeName());

    NodeList nodeList = node.getChildNodes();

    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentode = nodeList.item(0);

        System.out.println(currentode.getNodeName());

        if (currentode.getNodeType() == Node.ELEMENT_NODE) {

            Element element = (Element) currentode;
            iterateNodes(element);
        }
    }
}

public void run() throws ParserConfigurationException, SAXException, IOException {

    String path = "others.xml";

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setNamespaceAware(true);
    DocumentBuilder builder = factory.newDocumentBuilder();
    org.w3c.dom.Document document = builder.parse(path);

    document.getDocumentElement().normalize();

    iterateNodes(document.getDocumentElement());

}

您在Node currentode = nodeList.item(0)<---- 中编码，使用迭代器变量 i 更改它。

private void iterateNodes(Node node) {

    System.out.println("Node: " + node.getNodeName());
    NodeList nodeList = node.getChildNodes();

    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentode = nodeList.item(i);

        System.out.println(currentode.getNodeName());

        if (currentode.getNodeType() == Node.ELEMENT_NODE) {
            Element element = (Element) currentode;
            iterateNodes(element);
        }
    }
}
