String和Document相互轉換

一、使用最原始的javax.xml.parsers,標準的jdk api
// 字串轉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轉字串 TransformerFactory tf = TransformerFactory.newInstance(); Transformer t = tf.newTransformer(); t.setOutputProperty(/"encoding/",/"GB23121/");//解決中文問題,試過用GBK不行 ByteArrayOutputStream bos = new ByteArrayOutputStream(); t.transform(new DOMSource(doc), new StreamResult(bos)); String xmlStr = bos.toString(); //這裡的XML DOCUMENT為org.w3c.dom.Document
二、使用dom4j後程序變得更簡單
// 字串轉XML
String xmlStr = /"....../";
Document document = DocumentHelper.parseText(xmlStr);
// XML轉字串
Document document = ...;
String text = document.asXML();
//這裡的XML DOCUMENT為org.dom4j.Document
三、使用JDOM JDOM的處理方式和第一種方法處理非常類似
//字串轉XML String xmlStr = /"...../"; StringReader sr = new StringReader(xmlStr); InputSource is = new InputSource(sr); Document doc = (new SAXBuilder()).build(is); //XML轉字串 Format format = Format.getPrettyFormat(); format.setEncoding(/"gb2312/");//設定xml檔案的字元為gb2312,解決中文問題 XMLOutputter xmlout = new XMLOutputter(format); ByteArrayOutputStream bo = new ByteArrayOutputStream(); xmlout.output(doc,bo); String xmlStr = bo.toString(); //這裡的XML DOCUMENT為org.jdom.Document
四、JAVASCRIPT中的處理
//字串轉XML var xmlStr = /"...../"; var xmlDoc = new ActiveXObject(/"Microsoft.XMLDOM/"); xmlDoc.async=false; xmlDoc.loadXML(xmlStr); //可以處理這個xmlDoc了 var name = xmlDoc.selectSingleNode(/"/person/name/"); alert(name.text); //XML轉字串 var xmlDoc = ......; var xmlStr = xmlDoc.xml //這裡的XML DOCUMENT為javascript版的XMLDOM。
