虽然忙着准备组成原理的实验，还是有闲暇的时间写点小程序。这次写了一个遍历文件夹中的文件和文件夹，以层次结构生成XML。

首先写了两个类继承自Element类，用于生成XML的文件节点和文件夹节点

package stwolf.hustbaidu.java.learn.filelist;

import java.io.File;
import java.util.Date;
import org.jdom.Element;

@SuppressWarnings( " serial " )
public class FileElement extends Element
{
     public FileElement(File file)
    {
         super ( " File " );
         this .setAttribute( " AbsolutePath " ,file.getAbsolutePath());
         this .setAttribute( " Hidden " ,Boolean.toString(file.isHidden()));
         this .setAttribute( " canWrite " ,Boolean.toString(file.canWrite()));
         this .setAttribute( " canRead " ,Boolean.toString(file.canRead()));
         this .setAttribute( " TotalSpace " ,Long.toString(file.length() / 1024 ) + " KB " );
         this .setAttribute( " LastModified " ,( new Date(file.lastModified())).toString());
         this .addContent(file.getName());
    }
}

package stwolf.hustbaidu.java.learn.filelist;

import java.io.File;
import java.util.Date;

import org.jdom.Element;

@SuppressWarnings( " serial " )
public class DirectoryElement extends Element
{
     public DirectoryElement(File file) {
         super ( " Directory " );
         this .setAttribute( " AbsolutePath " ,file.getAbsolutePath());
         this .setAttribute( " Hidden " ,Boolean.toString(file.isHidden()));
         this .setAttribute( " canWrite " ,Boolean.toString(file.canWrite()));
         this .setAttribute( " canRead " ,Boolean.toString(file.canRead()));
         this .setAttribute( " LastModified " ,( new Date(file.lastModified())).toString());
         this .addContent(file.getName());
    }
}

接下来就是生成XML了，其中我用的是JDOM，相关的信息可以从http://www.jdom.org/了解到。

下面我们第一步创建文档，根节点是<Source></Source>

Document Doc;
Element root = new Element( " Source " );
Doc = new Document(root);

接下来我们按层次遍历文件目录树，这里用到了栈

int count;
        File tempFile;
        DirectoryElement tempDirectory;
        Stack < File > fileStack = new Stack < File > ();
        Stack < Element > directoryElements = new Stack < Element > ();
        File files[];
        fileStack.push(rootDirectory);
        directoryElements.push(root);
         while ( ! fileStack.isEmpty()) {
            count = 0 ;
            tempFile = fileStack.pop();
            tempDirectory = new DirectoryElement(tempFile);
            directoryElements.pop().addContent(tempDirectory);
            files = tempFile.listFiles();
             for ( int i = 0 ; i < files.length; i ++ ) {
                 if (files[i].isDirectory()) {
                    fileStack.push(files[i]);
                    directoryElements.push(tempDirectory);
                } else {
                    tempDirectory.addContent( new FileElement(files[i]));
                     ++ count;
                }
            }
            tempDirectory.setAttribute( " FileCount " , Integer.toString(count));
        }

最后是生成和保存xml文件

        XMLOutputter XMLOut = new XMLOutputter();
        File XMLOutput = new File(XMLPath);
        XMLOut.output(Doc, new FileOutputStream(XMLOutput));

下面是测试程序：

public static void main(String[] args) {
         try {
            XMLWriter.write( new File(
                     " C:\\Program Files\\Fiddler2 " ),
                     " C:\\Users\\ygui\\Desktop\\file.xml " );
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }

程序生成的XML如下
