SAXBuilder builder = new SAXBuilder();Document document = builder.build(new StringReader(credit));//格式化xml对象Format format = Format.getCompactFormat();//是否自闭和，默认为false，改为trueformat.setExpandEmptyElements(true);format.setEncoding("utf-8");//设置xml文件的字符为gb2312，解决中文问题XMLOutputter xmlout = new XMLOutputter(format);ByteArrayOutputStream bo = new ByteArrayOutputStream();xmlout.output(document, bo);credit = bo.toString();
