XML字符串和XML DOCUMENT的相互转换
本文涉及到XML字符串和Xml Document的转换问题，就各种XML解析器分别列举如下，以方便今后查阅。
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后程序变得更简单
// 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非常类似
//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\");//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(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);
//可以处理这个xmlDoc了

A couple of weeks ago, I had a plan to write an article and example code of using XML parser in Symbian OS. It seems that another Forum Nokia Champion, Paul Todd had the same idea. He posted a nice article about XML parser in Symbian OS 9.x to Forum Nokia Blogs. It's ......
