Question

你们麻烦啊？
给个例子看看行不？

Answer 1

给你个例子，其中有你想要的．import java.io.*;
import java.sql.*;
public class fileto{
    public static void main(String[] args){
        int b=1;
        String outfile="";
     String pathname="d:\\softhtml";
        long filepointer=0;
        long filelength=0;
        String s="";
        String filetxt="";
        File file=new File(pathname);
        if (file.isDirectory() )
        {
            String[] directory = file.list ();
            for (int i=0;i<directory.length;i++)
            {
              //在第一层子目录下
                File file1=new File(pathname+"\\"+directory[i]);
                if(file1.isDirectory()){
                    String[] directory1=file1.list();
                    for(int j=0;j<directory1.length;j++){
                        //在第二层子目录下
                        //System.out.println(directory1[j]+"\n");
                        File file2=new File(pathname+"\\"+directory[i]+"\\"+directory1[j]);
                        if(file2.isDirectory()){
                            String[] filename=file2.list();
                            for(int k=0;k<filename.length;k++){
                                File htmfile=new File(pathname+"\\"+directory[i]+"\\"+directory1[j]+"\\"+filename[k]);
                                if(htmfile.isFile()){
                                   //此处插入具体分析HTM文件的代码                                   try{
                                      RandomAccessFile afile=new RandomAccessFile(htmfile,"r");
                                      filepointer=0;
                                      filelength=afile.length();
                                      while(filepointer<filelength){
                                         s=afile.readLine()+"\n";
                                         //System.out.println(s);
                                        filetxt=filetxt+s;                                         filepointer=afile.getFilePointer();
                                      }
                                      afile.close();
                                   }
                                   catch(Exception e){
                                      System.out.println(e.getMessage());
                                   }                                   outfile="d:\\bianli\\"+Integer.toString(b)+".txt";
                                   try{
                                      DataOutputStream dos=new DataOutputStream(new FileOutputStream(outfile));
                                      dos.writeBytes(filetxt);
                                      dos.close();
                                   }
                                   catch(Exception ec){
                                      System.out.println(ec.getMessage());
                                   }
                                   
                                   if(filetxt.indexOf("</html>")<5){   
                                      System.out.println(htmfile.getPath()+"\n");
                                   }                                   
                                   
                                   filetxt="";
                                   b++;
                                }                            }
                        }
                    }
                }
            }
        }
    }}
