大學課程？ – Makky

我覺得一般算法如下：

文件讀入到一個緩衝
找到您標籤的第一個實例
繼續讀行，直到找到最後標籤
輸出這些線路

這可以很容易地完成JSOUP

Jsoup

這裏充滿工作example

import java.io.File; 
import java.io.IOException; 

import org.apache.commons.io.FileUtils; 
import org.jsoup.Jsoup; 
import org.jsoup.nodes.Document; 
import org.jsoup.select.Elements; 

public class Test { 

    public static void main(String args[]) throws IOException { 
     String path = Test.class.getResource("/test.txt").getPath(); 
     String string = FileUtils.readFileToString(new File(path)); 

     Document doc = Jsoup.parse(string); 
     Elements elementsByTag = doc.getElementsByTag("book"); 
     System.out.println(elementsByTag); 
    } 

}

的test.txt
