    2.

    3.Java代码

    4.1.String xmlStr = \“......\”;

    5.2.StringReader sr = new StringReader(xmlStr);

    6.3.InputSource is = new InputSource(sr);

    7.4.DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

    8.5.DocumentBuilder builder=factory.newDocumentBuilder();

    9.6.Document doc = builder.parse(is);

    10.String xmlStr = \“......\”;

    20.Java代码

    21.1.TransformerFactory  tf  =  TransformerFactory.newInstance();

    22.2.Transformer t = tf.newTransformer();

    23.3.t.setOutputProperty(\“encoding\”,\“GB23121\”);//解决中文问题,试过用GBK不行

    24.4.ByteArrayOutputStream  bos  =  new  ByteArrayOutputStream();

    25.5.t.transform(new DOMSource(doc), new StreamResult(bos));

    26.6.String xmlStr = bos.toString();
