下面我就各种XML技术对此问题的解决方法做个总结,和大家分享,也方便自己今后查阅。
一,使用JDOM(这是我最常使用的一种技术)
1.字符串转Document对象
String xmlStr = “…..”;
StringReader sr = new StringReader(xmlStr);
InputSource is = new InputSource(sr);
Document doc = (new SAXBuilder()).build(is);
2.Document对象转字符串
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();
注:Document为org.jdom.Document
二,使用最原始的javax.xml.parsers,标准的jdk api
1.字符串转Document对象
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);
2.Document对象转字符串
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();
注:Document为org.w3c.dom.Document
三,使用dom4j(这是最简单的方法)
1.字符串转Document对象
String xmlStr = “……”;
Document document = DocumentHelper.parseText(xmlStr);
2.Document对象转字符串
Document document = …;
String text = document.asXML();
注:Document为org.dom4j.Document
四,在JavaScript中的处理
1.字符串转Document对象
var xmlStr = “…..”;
var xmlDoc = new ActiveXObject(“Microsoft.XMLDOM”);
xmlDoc.async=false;
xmlDoc.loadXML(xmlStr);
//可以处理这个xmlDoc了
var name = xmlDoc.selectSingleNode(“/person/name”);
alert(name.text);
2.Document对象转字符串
var xmlDoc = ……;
var xmlStr = xmlDoc.xml
注:Document为javaScript版的XMLDOM
