本文介绍了如何在Java中将字符串转换为XML文档，并提供了将XML文档转换回字符串的方法。通过具体的代码示例展示了使用DocumentBuilderFactory和TransformerFactory进行转换的过程。

// 字符串转XML

Java代码
1.String xmlStr = \"......\";
2.StringReader sr = new StringReader(xmlStr);
3.InputSource is = new InputSource(sr);
4.DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
5.DocumentBuilder builder=factory.newDocumentBuilder();
6.Document doc = builder.parse(is);
String xmlStr = \"......\";
StringReader sr = new StringReader(xmlStr);
InputSource is = new InputSource(sr);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder=factory.newDocumentBuilder();
Document doc = builder.parse(is);

//XML转字符串

Java代码
1.TransformerFactory tf = TransformerFactory.newInstance();
2.Transformer t = tf.newTransformer();
3.t.setOutputProperty(\"encoding\",\"GB23121\");//解决中文问题，试过用GBK不行
4.ByteArrayOutputStream bos = new ByteArrayOutputStream();
5.t.transform(new DOMSource(doc), new StreamResult(bos));
6.String xmlStr = bos.toString();
TransformerFactory tf = TransformerFactory.newInstance();
Transformer t = tf.newTransformer();
t.setOutputProperty(\"encoding\",\"GB23121\");//解决中文问题，试过用GBK不行
ByteArrayOutputStream bos = new ByteArrayOutputStream();
t.transform(new DOMSource(doc), new StreamResult(bos));
String xmlStr = bos.toString();
