java xml特殊字符转义,如何在Java-XML中禁用/避免和符号转义？

I want to create a XML where blanks are replaced by  . But the Java-Transformer escapes the Ampersand, so that the output is  

Here is my sample code:

public class Test {

public static void main(String[] args) {

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder builder = factory.newDocumentBuilder();

Document document = builder.newDocument();

Element element = document.createElement("element");

element.setTextContent(" ");

document.appendChild(element);

ByteArrayOutputStream stream = new ByteArrayOutputStream();

Transformer transformer = TransformerFactory.newInstance().newTransformer();

StreamResult streamResult = new StreamResult(stream);

transformer.transform(new DOMSource(document), streamResult);

System.out.println(stream.toString());

}

}

And this is the output of my sample code:

 

Any ideas to fix or avoid that? thanks a lot!

Set the text content directly to the character you want, and the serializer will escape it for you if necessary:

element.setTextContent("u00A0");
