Java 小程式 解析 down.dl

自己寫的一點小東西，處理ZcocoComic Viewer運作過程中，down.dl 的暫存檔，使之創造一個批次檔，直接下載檔案。

其中用到「讀檔」「寫檔」「Regular Expressions」「字串處理」

注意事項：如果要在寫入的文字檔中換行，需要加入 "\r\n"

另附 轉換String to int
int x = Integer.parseInt(str); <-------字串轉換成int的整數數值 ;

程式碼：
package downdl;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class ext01 {
public static void main(String[] args) throws IOException {

 FileReader fr = new FileReader(
   "n:/ZcocoComic_1.00_cn/support/workshop/down.dl");
 BufferedReader buf = new BufferedReader(fr);
 String s;
 String t;
 String picDir = "", pageName = "", wget = "";

 String regEx = "picSrc\\[[0-9][0-9]*\\] ?= ?'";

 while ((s = buf.readLine()) != null) {
  s = s.replace("%7C", "|");
  s = s.replace("\t", " ");


  // pageName
  if (s.indexOf("pageName = ") != -1) {
   pageName = s.substring(s.indexOf("pageName = \"") + 12, s.lastIndexOf("\""));

   System.out.println("mkdir " + pageName);
   System.out.println("cd " + pageName);
  }

  // picDir
  if (s.indexOf("url=") != -1) {
   picDir = s.substring(s.indexOf("url=") + 4, s.indexOf("\";"));

  }

  Pattern pattern = Pattern.compile(regEx);
  Matcher m = pattern.matcher(s);

  while (m.find()) {

   t = s.substring(m.end(), s.indexOf("';"));
   System.out.println("wget \"" + picDir + t + "\"");
   wget += ("wget \"" + picDir + t + "\"\r\n");

  }

  // System.out.println(s);

 }

 t = "M:/DEL/" + pageName + ".bat";

 FileWriter fw = new FileWriter(t);
 BufferedWriter output = new BufferedWriter(fw);
 output.write("mkdir " + pageName + "\r\n");
 output.write("cd " + pageName);
 output.write(13); // \r 13是歸位字元
 output.write(10); // \n 10是換行字元
 output.write(wget);
 System.out.println(t);
 output.close();
}
}
