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