将Excel文件生成xml文件

一.下载jxl.jar（用来读取excel文件）和jdom（用来生成xml文件）
二.准备需要转换的数据，如图
三.代码部分
1.先写个类来处理如何生成xml

import java.io.FileOutputStream; 
import java.io.IOException; 
import java.util.ArrayList; 
import org.jdom.*; 
import org.jdom.output.XMLOutputter; 

public class GenEduXml { 
    Document myDoc; 
    Element myRoot; 
    Element subRoot; 
     
    public void init() throws IOException, JDOMException{ 
        myDoc = new Document();         //创建document 
        Attribute att1 = new Attribute("grade","3");         
        Attribute att2 = new Attribute("version","高级"); 
        ArrayList<Attribute> list = new ArrayList<Attribute>(); 
        list.add(att1); 
        list.add(att2); 
        myRoot = new Element("subChannel").setAttribute("id","英语"). 
                addContent(new Element("questions").setAttributes(list));    
        //此处注意用setAttribute设置属性时，属性个数大于1时参数为Collection类 
         
        myDoc.setRootElement(myRoot);       //设置根节点 
        subRoot = myRoot.getChild("questions");    //移动到需要插入数据的节点 
    } 
     
    //写一个用来插入excel中一行数据的函数，注意如何形成所需结构 
    public void addOneItem(String question,String anwser,String option1,String option2,String option3){ 
        subRoot.addContent(new Element("questionItem").setAttribute("answerid",anwser). 
                addContent(new Element("text").setText(question)). 
                addContent(new Element("answer").setAttribute("id","1").setText(option1)). 
                addContent(new Element("answer").setAttribute("id","2").setText(option2)). 
                addContent(new Element("answer").setAttribute("id","3").setText(option3))); 
    } 
    //将数据导出为xml文件的函数 
    public void toXml()throws IOException, JDOMException{ 
        XMLOutputter   XMLOut   =   new   XMLOutputter(); 
        XMLOut.output(myDoc,   new   FileOutputStream("test1.xml")); 
    } 
}
2.写主函数类ExcelToXml，主函数中需要读取excel并调用GenEduXml


import java.io.File;  
import jxl.*;  

public class ExcelToXml { 
    public static void main(String args[]){ 
        try{ 
            Workbook workbook = Workbook.getWorkbook(new File("D:\\myfile.xls")); 
            Sheet sheet = workbook.getSheet(0);     //获得第一个sheet 
             
            GenEduXml gen = new GenEduXml();    //创建生成xml文件的实例 
            gen.init(); 
             
            Cell[] a = sheet.getColumn(0);  //获得第一列 
            Cell[] b = sheet.getColumn(1); 
            Cell[] c = sheet.getColumn(2);  
            Cell[] d = sheet.getColumn(3);  
            Cell[] e = sheet.getColumn(4);  
             
            for(int i=0;i<a.length;i++){ 
                gen.addOneItem(a[i].getContents(), b[i].getContents(), c[i].getContents(), d[i].getContents(), e[i].getContents()); 
            } 
            workbook.close(); 
            gen.toXml();     
        }catch(Exception e){ 
            e.printStackTrace(); 
        } 
        System.out.println("Xml has been biult!"); 
    } 
}
这样就可以形成所需的xml文件了
