主要涉及转化:
从String转化为document再到xml
从xml转化为document再到String
[java]
- xml转化为string：
- public static String xmlFile2String(String fileName) throws SAXException, IOException, ParserConfigurationException, TransformerFactoryConfigurationError, TransformerException
- {
- DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
- InputSource inputSource = new InputSource(fileName);
- Document document = documentBuilderFactory.newDocumentBuilder().parse(inputSource);
- StringWriter sw = new StringWriter();
- Transformer serializer = TransformerFactory.newInstance().newTransformer();
- serializer.transform(new DOMSource(document), new StreamResult(sw));
- return sw.toString();
- }
- doc转化为string：
- DOMSource domSource = new DOMSource(doc);
- StringWriter writer = new StringWriter();
- StreamResult result = new StreamResult(writer);
- TransformerFactory tf = TransformerFactory.newInstance();
- Transformer transformer = tf.newTransformer();
- transformer.transform(domSource, result);
- System.out.println( writer.toString());
- doc转化为xml：
- TransformerFactory tFactory = TransformerFactory.newInstance();
- Transformer transformer = tFactory.newTransformer();
- DOMSource source = new DOMSource(doc);
- FileOutputStream outStream = new FileOutputStream( "outFile.xml ");
- StreamResult result = new StreamResult(outStream);
- transformer.transform(source, result);
- doc的初始化：
- DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
- DocumentBuilder db = null;
- try {
- db = dbf.newDocumentBuilder();
- } catch (ParserConfigurationException pce) {
- System.err.println(pce);
- System.exit(1);
- }
- Document doc = null;
- doc = db.newDocument();
- 用读文件的方式把xml变成string：
- FileInputStream in = new FileInputStream( "DataTest.xml ");
- BufferedInputStream bufferin=new BufferedInputStream(in);
- byte c[]= new byte[1000];
- int n=0;
- StringBuffer bs=new StringBuffer();
- while ((n=bufferin.read(c))!=-1)
- {String temp=new String (c,0,n);//
- bs.append(temp);
- }
