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
