Java：如何从Java中的xml获取属性名称？（JDOM）

Question

Java：如何使用JAVA-JDOM获取节点的属性名称？ 例如，

<xml>
    <Test id="001"></Test>
</xml>

输出应为：

id

我的Java程序：在______中需要获取源文件中的节点的属性名称。 该程序只将“ _Test”添加到xml文件中的所有节点并替换相同的文件。

try
    {
    XMLOutputter  xmlOut = new XMLOutputter();
    SAXBuilder builder = new SAXBuilder();
    File xmlFile = new File("D://Test//sample.xml");
    Document document = (Document) builder.build(xmlFile);
    Element rootNode = document.getRootElement();
    String Original_data=xmlOut.outputElementContentString(rootNode);
    String Test_Data="",Output_Data;
    List<?> list = rootNode.getChildren();
    PrintStream out = new PrintStream(new FileOutputStream("D://Test/sample.xml"));
    Element node=null;
    for(int i=0;i<list.size();i++)
      {
        node=(Element) list.get(i);
        Test_Data+="<"+node.getName()+"_Test "+__________+"="+node.getAttributeValue(________)+">"; //In ______ Needs to get Only Name of Attribute.

        List<?> n_list=node.getChildren();
        Element node2=null;
        for(int j=0;j<n_list.size();j++)
        {
            node2=(Element) n_list.get(j);

              String Str = new String(xmlOut.outputString(node2));
              Test_Data+=Str.replace(node2.getName(),node2.getName()+"_Test");
        }
        Test_Data+="</"+node.getName()+"_Test>";
      }
    out.println("<"+rootNode.getName()+">"+Original_data+Test_Data+"</"+rootNode.getName()+">");
    }
