遍历文件夹生成XML

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

  <?xml version="1.0" encoding="UTF-8" ?>
