java - 用于多个输入文件的 HTML 解析器

Question

我想一次选择多个 html 文件并使用 html 解析器仅提取文本，每个 html 文件将创建一个单独的文本文件。任何人都可以为此建议java代码。

`FileReader f0 = new FileReader("j.html");
StringBuilder sb = new StringBuilder();
 BufferedReader br = new BufferedReader(f0);
while((temp1=br.readLine())!=null)
  { sb.append(temp1); }
String para = sb.toString().replaceAll("<br>","\n");
String textonly = Jsoup.parse(para).text();
System.out.println(textonly);
FileWriter f1=new FileWriter("j.txt");
char buf1[] = new char[textonly.length()];
textonly.getChars(0,textonly.length(),buf1,0);
for(i=0;i<buf1.length;i++) {
 if(buf1[i]=='\n')
f1.write("\r\n");
f1.write(buf1[i]);
}`

我有这段代码，但一次只占用一个文件。我想选择多个文件。

你不能把你的代码放在一个循环中吗？类似的东西（未测试）：

// loop over files you want to change
for (int i = 1; i < 1000; i++) {
   FileReader f0 = new FileReader(i + ".html");
   StringBuilder sb = new StringBuilder();
   BufferedReader br = new BufferedReader(f0);
   while((temp1=br.readLine())!=null) { 
      sb.append(temp1); 
   }
   String para = sb.toString().replaceAll("<br>","\n");
   String textonly = Jsoup.parse(para).text();
   System.out.println(textonly);
   // stick .txt on the end of the filename to write out
   FileWriter f1=new FileWriter(i + ".txt"); 
   char buf1[] = new char[textonly.length()];
   textonly.getChars(0,textonly.length(),buf1,0);
   for(i=0;i<buf1.length;i++) {
      if(buf1[i]=='\n') {
         f1.write("\r\n");
      }
      f1.write(buf1[i]);
   }
