问题描述

我的目录结构形式为:

base_directory / level_one_a level_one_b level_one_c /

然后在 level_one_x 中的所有这些目录中是多个后续目录,即

then within all those directories in level_one_x are a multitude of subsequent directories, i.e.

/ level_one_a_1 level_one_a_2 level_one_a_3 ...

等等,以 level_one_b & level_one_c

and so on for level_one_b & level_one_c

然后在 level_one_a_1 内,即 level_one_a_1_I level_one_a_1_II level_one_a_1_III level_one_a_1_IV ...

then inside of level_one_a_1 we have more still, i.e. level_one_a_1_I,level_one_a_1_II,level_one_a_1_III,level_one_a_1_IV...

然后最后在 level_one_a_1_IV 里面,以及所有处于同一级别的文件,都是我要操作的文件。

Then finally inside of level_one_a_1_IV, and all those on the same level, are the files I want to operate on.

我想用一种简短的方式来表示,即 start / 一个 / 两个 / 三个 / * files *

I guess a shorter way to say that would be start/one/two/three/*files*

文件很多,并且我想用我编写的简单Java程序来处理它们:

There are many many files and I want to process them all with a simple java program I wrote:

    try 
    {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) 
        {

            sb.append(line);
            sb.append(System.lineSeparator());
            line = br.readLine();
        }
        String everything = sb.toString();



        Document doc = Jsoup.parse(everything);
        String link = doc.select("block.full_text").text();
        System.out.println(link);


    }
    finally 
    {
        br.close();
    }

它使用jsoup

我想构建此脚本,以便程序可以自动导航此目录结构并抓取每个文件,然后使用缓冲读取器和文件读取器使用该脚本处理该文件,我想,我该怎么办?方便吗?我尝试实施此解决方案,但我无法不能正常工作。

I'd like to construct this script such that the program can navigate this directory structure autonomously and grab each file then process it with that script, using buffered reader and file reader I guess, how can I facilitate that? I tried implementing this solution but I couldn't get it to work.

理想情况下,我想使用唯一名称输出其处理的每个文件,即该文件名为 00001.txt 可能会将其另存为 00001_output.txt ,但这是另一种颜色的马

Ideally I want to output each file it processes with a unique name, i.e. is the file is named 00001.txt it might save it as 00001_output.txt but, that's a horse of a different colour

推荐答案

只需使用 java.io.File 及其方法 listFiles
请参见javadoc 文件API

Just use java.io.File and its method listFiles. See javadoc File API
