string 转化xml && xml转化为string

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     

string 转化xml xml转化为string
