  首先，代码是从百度贴的，简单说下，这里如果要解析注释的话，就不能用迭代器Iterator来迭代element了，从代码可以看出，element只是node的接口之一，而注释节点的继承结构里没有element接口，需要使用如下的遍历方式才能得到，原理大概是这样，如有不明白的地方，欢迎追问
  

  Element root= doc.getRootElement();

  for (int i = 0, size = root.nodeCount(); i < size; i++) 

     {
                         Node node = root.node(i);
                         if (node instanceof Element) {
                          System.out.println("This is a Element!");
                          prinContent(node);
                             System.out.println();
                         } else if(node instanceof org.dom4j.Comment){
                          System.out.println("This is a Comment!");
                          prinContent(node);
                          System.out.println();
                         }else{
                          System.out.println("This is a Nothing!");
                          prinContent(node);
                         }
                     }
