JAVA操作XML二(转换关系):String --document--xml --document--String

主要涉及转化:

从String转化为document再到xml

从xml转化为document再到String

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); }
