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
