xml文件我放在D:/HBJT_FILE/test.xml

xml文件内容为：

<?xml version="1.0" encoding="GB2312"?>

<RESULT>

<VALUE>　　

<NO>A1234</NO>　　

<ADDR>河北省</ADDR>

</VALUE>

<VALUE>　　

<NO>B1234</NO> 　

<ADDR>石家庄</ADDR>

</VALUE>

</RESULT>

//**byte[]转换成String*/

BASE64Encoder enc=new BASE64Encoder();

String xmlString =enc.encode(xml);

实现类中的代码：

//**String转换成byte[]*/

byte[] buffer = new BASE64Decoder().decodeBuffer(xmlString);

//**将byte[]写入xml文件*/

/*FileOutputStream out = new FileOutputStream("D:/HBJT_FILE/test.xml");

out.write(xml);

out.close(); */

SAXBuilder builder = new SAXBuilder();

Document doc = builder.build(new File("D:/HBJT_FILE/test.xml"));

Element foo = doc.getRootElement();

List allChildren = foo.getChildren();

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

System.out.print("地址1:"+ ((Element) allChildren.get(i)).getChild("NO").getText());

System.out.println("地址2:"+ ((Element) allChildren.get(i)).getChild("ADDR").getText());

}
