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
