Question

这是我的XML

    <action>
    <name>EDIT</name>
    <type>123</type>
    <services>
        <service>
         this is child node
        </service>
    <services>
 </action>

上面的XML具有根节点和childNode，，，所以我们想找到具有任何childNodes或text的childNodes，因此要找到它，我们在下面的Java代码中进行了解析

File fXmlFile = new File("/opt/staff.xml");
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(fXmlFile);
        doc.getDocumentElement().normalize();
        NodeList nList1 = doc.getElementsByTagName("action");
        // for loop
        for (int i = 0; i < nList1.getLength(); i++) {
            Node node = nList1.item(i);
            NodeList childNodeList = node.getChildNodes();
            for (int childCount = 0; childCount < childNodeList.getLength(); childCount++) {
                Node gChild = childNodeList.item(childCount);                   
                if (Node.ELEMENT_NODE != childNodeList.getNodeType()) {
                    continue;
                } // end of if

                if(gChild.hasChildNodes()){
                     System.out.print("having child node ");
                }else{
                     System.out.print("not having child node ");
                }
            }//end Of For
        }//end Of For

因此，当我们执行上述代码时，它应该像这样打印出来

not having child node
not having child node
having child node

因为<name>和<type>节点不具有childNode，而<services>节点具有childNode，但它正在打印这样的输出

having child node
having child node
having child node

当我在Google上搜索此问题时，我获得了以下链接，我已经尝试过，但是我的问题没有解决 How to know if a tag contains a value or another tag? 谁能帮我

如何知道xml节点是否包含值或另一个节点？
