以下：

/**
         * <XML字符串转换成XML Document >
         * <功能详细描述>
         * @param sXml
         * @return
         * @see [类、类#方法、类#成员]
         */
        public Document changeStringToXML(String sXml)
        {
            StringReader sr = new StringReader(sXml);
            InputSource is = new InputSource(sr);
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document doc = builder.parse(is);
    	return doc;
        }

将XML生成在指定路径：

/**
         * 生成文件
         * @param path
         * @param doc
         * @return  -1:生成xml出错    0：创建成功   1：所要上报的文件已生成
         */
        public int writeXML(String path, Document doc)
        {
            File markFile = new File(path);
            if (markFile.exists())
            {
                return 1;
            }
            FileOutputStream fos;
            try
            {
                fos = new FileOutputStream(path);
            }
            catch (FileNotFoundException e)
            {
                logger.debug("数据上报XML文件输出出错：系统找不到指定路径");
                return -1;
            }

            try
            {
                outwriter = new OutputStreamWriter(fos, "UTF-8");
                Source sorce = new DOMSource(doc);
                Result result = new StreamResult(outwriter);
                Transformer trans;
                try
                {
                    trans = TransformerFactory.newInstance().newTransformer();
                    trans.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
                    trans.transform(sorce, result);
                    try
                    {
                        fos.close();
                    }
                    catch (IOException e)
                    {
                        e.printStackTrace();
                    }
                    return 0;
                }
                catch (TransformerConfigurationException e)
                {
                    e.printStackTrace();
                    return -1;
                }
                catch (TransformerFactoryConfigurationError e)
                {
                    e.printStackTrace();
                    return -1;
                }
                catch (TransformerException e)

                    return -1;
                }
            }
            catch (UnsupportedEncodingException e1)
            {
                e1.printStackTrace();
