Dom转换为字符串 ：

view plaincopy to clipboardprint?/** 
     * XML org.w3c.dom.Document 转 String 
     */  
    public static String docToString(Document doc) {   
        // XML转字符串    
        String xmlStr = "";   
        try {   
            TransformerFactory tf = TransformerFactory.newInstance();   
            Transformer t = tf.newTransformer();   
            t.setOutputProperty("encoding", "UTF-8");// 解决中文问题，试过用GBK不行    
            ByteArrayOutputStream bos = new ByteArrayOutputStream();   
            t.transform(new DOMSource(doc), new StreamResult(bos));   
            xmlStr = bos.toString();   
        } catch (TransformerConfigurationException e) {   
            // TODO Auto-generated catch block    
            e.printStackTrace();   
        } catch (TransformerException e) {   
            // TODO Auto-generated catch block    
            e.printStackTrace();   
        }   
        return xmlStr;   
    }  

字符串转换为org.w3c.dom.document:

view plaincopy to clipboardprint?/** 
     * String 转 XML org.w3c.dom.Document 
     */  
    public static Document stringToDoc(String xmlStr) {   
        //字符串转XML    
        Document doc = null;   
        try {   
            xmlStr = new String(xmlStr.getBytes(),"UTF-8");   
            StringReader sr = new StringReader(xmlStr);   
            InputSource is = new InputSource(sr);   
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();   
            DocumentBuilder builder;   
            builder = factory.newDocumentBuilder();   
            doc = builder.parse(is);   
               
        } catch (ParserConfigurationException e) {   
            System.err.println(xmlStr);   
            // TODO Auto-generated catch block    
            e.printStackTrace();   
        } catch (SAXException e) {   
            System.err.println(xmlStr);   
            // TODO Auto-generated catch block    
            e.printStackTrace();   
        } catch (IOException e) {   
            System.err.println(xmlStr);   
            // TODO Auto-generated catch block    
            e.printStackTrace();   
        }   
        return doc;   
    }
