Very simply: use an XML library. That way it will actually be right instead of requiring detailed knowledge of bits of the XML spec.

You can use JAXB for the XML generation. Annotate your Model-Class with @XmlRootElement

Then you can use JAXB for marshalling the XML-Object:

try {
  JAXBContext context = JAXBContext.newInstance(Person.class);

  Marshaller m = context.createMarshaller();
  m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

  Person object = new Person();
  object.setPersonName("Sam & Pat");
  object.setSal("> than 10000");

  m.marshal(object, System.out);
} catch (JAXBException e) {
  e.printStackTrace();
}

The output will be

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<person>
    <personName>Sam &amp; Pat</personName>
    <sal>&gt; than 10000</sal>
</person>
