Can someone tell me why my code doesn't pass?

Question about the task

Introducing tags

Java Core, Level 9, Lesson 11

Under discussion

I am stuck, because when I test on my IDE, I get the proper output. Is there an edge case I need to account for?

Read from the console the name of a file containing HTML.

Example:
Info about Leela Leela Turanga
Supergirl

The main method's first parameter is a tag name. For example, "span".
Display all tags that match the specified tag.
The order should match their order in the file, each tag on a new line.
The number of spaces, newline characters (\n), or carriage returns (\r) does not affect the result.
The file does not have a CDATA tag. Each opening tag has a separate closing tag, and there are no self-closing tags.
Tags may have nested tags.

Example output:
Leela Turanga Leela Turanga Super girl

Tag templates:
<tag>text1</tag> <tag text2>text1</tag> <tag text2>text1</tag>

text1 and text2 can be empty

Requirements:

The program must read the file name from the console (use BufferedReader).
The BufferedReader used for reading input from the console must be closed after use.
The program must read the file's contents (use FileReader).
The file input stream (FileReader) must be closed.
The program must write to the console all the tags that match the tag specified by the argument passed to the main method.

package com.codegym.task.task19.task1918; /* Introducing tags */ import java.io.*; import java.util.regex.Matcher; import java.util.regex.Pattern; public class Solution { public static void main(String[] args) throws IOException { StringBuilder sb = new StringBuilder(); try (BufferedReader buff = new BufferedReader(new InputStreamReader(System.in)); BufferedReader input = new BufferedReader(new FileReader(buff.readLine()))) { while (input.ready()) sb.append(input.readLine()); } Pattern pattern = Pattern.compile("<" + args[0] + ".*?>.*<\\/" + args[0] + ">", Pattern.MULTILINE); Matcher m = pattern.matcher(sb.toString().replaceAll("\n", "")); while (m.find()) System.out.println(m.group()); } }

I get different results. Despite the linebreak line 2 missing your code gives: Leela TurangaSupergirl desired result: Leela Turanga Leela Turanga Super girl edit: the site renders the span tags useless but I hope you get what I mean [span]Leela Turanga[/span] is missing (the nested tag)
