本文介绍如何使用Java从XML文件中读取数据并将其转换为对象，同时也展示了如何将对象序列化回XML文件的方法。

1.unmarshal from file

"input.xml" -> Object

            // unmarshal customer information from file
            IBindingFactory bfact = BindingDirectory.getFactory(Order.class);
            IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
            FileInputStream in = new FileInputStream("input.xml");
            Order order = (Order)uctx.unmarshalDocument(in, null);

2.marshal object to file

Object -> "out.xml"

 // marshal object back out to file (with nice indentation, as UTF-8)
            IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(2);
            FileOutputStream out = new FileOutputStream("out.xml");
            mctx.setOutput(out, null);
            mctx.marshalDocument(order);
