java使用dom4j解析xml（通用）

​​xml样例如下​​

<Result>
        <A>a</A>
        <Test>
              <B>b</B>
              <Test1>
                     <C>c</C>
                          ...
              </Test1>
        </Test>
</Result>

            }   
        }
    }
    System.out.println(a);
    System.out.println(b);
    System.out.println(b);
