使用Java的DOM XML API在XML中解析Ampersand

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.newDocument();
Element root = doc.createElement("root");
doc.appendChild(root);

Text text = doc.createTextNode("This is a text with an ampersand: &");
root.appendChild(text);

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
transformer.transform(new DOMSource(doc), new StreamResult(System.out));

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>This is a text with an ampersand: &amp;</root>
