jdom读取xml

用jdom读取xml文件，如果xml文件如下格式：<?xml version="1.0" encoding="UTF-8"?><users><user><name>BASIC</name><pass>Example Basic Authentication Area</pass></user></users>很容易读出name的值：File f = new File(filepath);FileInputStream f1 = new FileInputStream(f);SAXBuilder sb = new SAXBuilder();Document doc = sb.build(f1);Element root = doc.getRootElement();java.util.List users = root.getChildren();Element user =(Element)users.get(0);Element name = user.getChild("name");String str = name.getText();System.out.println("str:"+str);如果xml文件是如下格式：<?xml version="1.0" encoding="UTF-8"?><users><user><property name="name">BASIC</property><property name="pass>"Example Basic Authentication Area</property></user></users>如何读出name的值，改如何写那如何得到 child的值。
