如何用jdom得到相同节点的属性和内容


public class TestElementLength
{
    static String xmlContent;
    public static void init()
    {
        xmlContent = "<?xml version=\"1.0\" encoding=\"GB2312\"?>"
            + "<lib>"
            + "<book>"
            + "<name>Java</name>"
            +"<author>tom</author>"
            +"<author>jack</author>"
            + "</book>"
            + "<book>"
            + "<name>XML</name>"
            + "<pubdate>2002-10-07</pubdate>"
            + "</book>"
            + "</lib>";
    }    public static void outputXml()
    {
        try
        {
            org.jdom.input.SAXBuilder sb = new org.jdom.input.SAXBuilder();
            org.jdom.Document doc = sb.build(new java.io.
                                             StringBufferInputStream(xmlContent));
            org.jdom.Element root = doc.getRootElement();
            java.util.List books = root.getChildren("book"); //得到根元素所有子元素的集合
            for(int i=0;i<books.size();i++)
            {
                org.jdom.Element book =(org.jdom.Element) books.get(i);
                System.out.println(book.getChild("name").getText());
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
    public static void main(String[] args)
    {
        init();
        outputXml();
    }
}
