jdom如何添加子元素

[leon_lee_83]

//我的xml文件
<?xml version="1.0" encoding="GBK"?>
<addresslist>
<address>长宁</address>
<address>宝山</address>
<address>徐汇</address>
</addresslist>

//我想通过下面函数向xml文件添加<address>元素，使用jdom.
//String xml 为文件路径
//String addr 为要添加的字段内容

public void insertAddressXML(String xml, String addr) {
// TODO Auto-generated method stub
SAXBuilder sb = new SAXBuilder();
Document doc;
try {
doc = sb.build(new FileInputStream(xml));
Element root = doc.getRootElement();

Element address = new Element("address");
address.setText(addr);
root.addContent(address);//这里怎么添加元素

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

//我在调用方法时并没有写入元素
address addr = new addressImp() ;
String xml="F:\\address.xml";
addr.insertAddressXML(xml, "虹口");
//我想的到的结果是这样的
<?xml version="1.0" encoding="GBK"?>
<addresslist>
<address>长宁</address>
<address>宝山</address>
<address>徐汇</address>
<address>虹口</address>
</addresslist>
