java xml和string互相转换

使用开源jar包 dom4j


package com.webdesk.swing.powertable.util;


import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;

public class XmlUtil {

    public static String xmlChangeString(String fileName){
        try {
            SAXReader saxReader = new SAXReader();
            Document tempDocument = saxReader.read(XmlUtil.class.getClassLoader().getResourceAsStream(fileName));
            return tempDocument.asXML();
        } catch (DocumentException e) {
            e.printStackTrace();
        }
        return null;
    }
    
    public static void strChangeXML(String str) throws IOException {
           SAXReader saxReader = new SAXReader();
           Document document;
           try {
            document = saxReader.read(new ByteArrayInputStream(str.getBytes("UTF-8")));
            OutputFormat format = OutputFormat.createPrettyPrint();
            /** 将document中的内容写入文件中 */
            XMLWriter writer = new XMLWriter(new FileWriter(new File("src/com/webdesk/swing/powertable/digester/cctv.xml")),format);
            writer.write(document);
            writer.close();
           } catch (DocumentException e) {
            e.printStackTrace();
           }

   }
}
