一、使用最原始的javax.xml.parsers，标准的jdk api

// 字符串转XML

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

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();

这里的XML DOCUMENT为org.w3c.dom.Document

二、使用dom4j后程式变得更简单

// 字符串转XML     String xmlStr = \"......\";    Document document = DocumentHelper.parseText(xmlStr);        // XML转字符串     Document document = ...;    String text = document.asXML();    //这里的XML DOCUMENT为org.dom4j.Document

三、使用JDOM

JDOM的处理方式和第一种方法处理很类似

//字符串转XML     String xmlStr = \".....\";    StringReader sr = new StringReader(xmlStr);   InputSource is = new InputSource(sr);   Document doc = (new SAXBuilder()).build(is);     //XML转字符串     Format format = Format.getPrettyFormat();    format.setEncoding(\"gb2312\");//配置xml文档的字符为gb2312，解决中文问题    XMLOutputter xmlout = new XMLOutputter(format);   ByteArrayOutputStream bo = new ByteArrayOutputStream();   xmlout.output(doc,bo);    String xmlStr = bo.toString();    //这里的XML DOCUMENT为org.jdom.Document

四、JAVASCRIPT中的处理

//字符串转XML     var xmlStr = \".....\";    var xmlDoc = new ActiveXObject(\"Microsoft.XMLDOM\");   xmlDoc.async=false;    xmlDoc.loadXML(xmlStr);    //能够处理这个xmlDoc了     var name = xmlDoc.selectSingleNode(\"/person/name\");   alert(name.text);        //XML转字符串     var xmlDoc = ......;    var xmlStr = xmlDoc.xml      //这里的XML DOCUMENT为javascript版的XMLDOM
