Answer 1

String xmlURL = "myXml.xml";
javax.xml.parsers.DocumentBuilder builder = javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder(); 
   org.w3c.dom.Document doc = builder.parse(xmlURL); 
         
   org.w3c.dom.Element root = doc.getRootElement();
   org.w3c.dom.Element name = doc.createElement("name"); 
   将wang.appendChild(doc.createTextNode("Tom")); 
   root.appendChild(wang); 
   javax.xml.transform.Transformer transformer =               javax.xml.transform.TransformerFactory.newInstance().newTransformer(); 
   transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "gb2312"); 
   transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes"); 
    
   transformer.transform(new javax.xml.transform.dom.DOMSource(doc),new javax.xml.transform.stream.StreamResult(outFile));

Answer 2

上面有一个错误：
String xmlURL = "myXml.xml";
javax.xml.parsers.DocumentBuilder builder = javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder(); 
   org.w3c.dom.Document doc = builder.parse(xmlURL); 
         
   org.w3c.dom.Element root = doc.getRootElement();
   org.w3c.dom.Element name = doc.createElement("name"); 
   将wang.appendChild(doc.createTextNode("Tom")); 
   root.appendChild(name); 
   javax.xml.transform.Transformer transformer =               javax.xml.transform.TransformerFactory.newInstance().newTransformer(); 
   transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "gb2312"); 
   transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes"); 
    
   transformer.transform(new javax.xml.transform.dom.DOMSource(doc),new javax.xml.transform.stream.StreamResult(outFile));
