dom4j element attribute

//获取dom对象

SAXReader reader = new SAXReader();

 Document doc = reader.read(new File(fileName));

 doc.getRootElement();

 遍历XML树

例子：

SAXReader reader = new SAXReader();

Document doc=reader.read(new File("MyXml.xml"));

    Element root=doc.getRootElement();

    List rootList=(List) root.elements("student");

   

    System.out.println(rootList.size());

    for(int i=0;i<rootList.size();i++)

    {

    Element e=(Element) rootList.get(i);

    Element age=e.element("age");

    Element name=e.element("name");

    System.out.println(age.getText()+name.getText());

    }

 for ( Iterator i = root.elementIterator(); i.hasNext(); ) {

       Element element = (Element) i.next();

       // do something

    }

    // 枚举名称为foo的节点

    for ( Iterator i = root.elementIterator(foo); i.hasNext();) {

       Element foo = (Element) i.next();

       // do something

    }

    // 枚举属性

    for ( Iterator i = root.attributeIterator(); i.hasNext(); ) {   //id name type

       Attribute attribute = (Attribute) i.next();

     System.out.println(attribute.getName());

System.out.println(attribute.getText());

    }

  System.out.println(element.getName());

System.out.println(element.getText());

List rootList=(List) root.elements("student");

    for(int i=0;i<rootList.size();i++)

    {

    Element e=(Element) rootList.get(i);

    System.out.println(e.getName());

    }
