How to split the text file individually.

[kelvin Seow]

Hi,

I am looking to split the line in the text file to individual text file.

Example in my current text file(RetrieveFile.txt):
<?xml version="1.0" encoding="UTF-8"?><ERRORACK><HEADER><MESSAGE_TYPE>ErrorAck</MESSAGE_TYPE><MESSAGE_ID>20160104171116001</MESSAGE_ID><ERROR_FILE>SCPreClrDec</ERROR_FILE><SEND_DATETIME>2016-01-04T17:11:16</SEND_DATETIME></HEADER><DETAIL><ERRORACK_ID>CERR20160104171116000001</ERRORACK_ID><RECORD_ID>CDCC20070604010101000001</RECORD_ID><REASON><REASON_CODE>908</REASON_CODE><REASON_REMARK>Container Information Not Found</REASON_REMARK></REASON></DETAIL></ERRORACK>

<?xml version="1.0" encoding="UTF-8"?><ERRORACK><HEADER><MESSAGE_TYPE>ErrorAck</MESSAGE_TYPE><MESSAGE_ID>20160104170749001</MESSAGE_ID><ERROR_FILE>SCPreClrDec</ERROR_FILE><SEND_DATETIME>2016-01-04T17:07:49</SEND_DATETIME></HEADER><DETAIL><ERRORACK_ID>CERR20160104170749000001</ERRORACK_ID><RECORD_ID>CDCC20070604010101000001</RECORD_ID><REASON><REASON_CODE>908</REASON_CODE><REASON_REMARK>Container Information Not Found</REASON_REMARK></REASON></DETAIL></ERRORACK>

I want to split into RetrieveFile1 and RetrieveFile2 but i do not know how to split it. Here is my code for it.
public class split {

	private static int filenumber;
	private static int permitLastNum;
	private static String msgTxt;
	
	public static void main(String[] args) throws SQLException, IOException {
		BufferedReader bufferedReader = null;
		BufferedWriter bufferedWriter = null;
		try {
		    bufferedReader = new BufferedReader(new FileReader("D:/randomTesting/retrieveFile.txt"));
		    int count =1;
		    bufferedWriter = new BufferedWriter(new FileWriter("D:/randomTesting/newFile" + count + ".txt"));
		    String s = "";
		    while ((s = bufferedReader.readLine()) != null) {
		    		/*bufferedWriter.write(s);
		    		bufferedWriter.newLine();
		    		count++;
		    		System.out.println(count);*/
		        bufferedWriter.write(s);
		        count++;
		        // write a new line
		        bufferedWriter.newLine();
		        System.out.println(s);
		        System.out.println(count);
		        // flush
		        bufferedWriter.flush();
		    }
		} catch (FileNotFoundException e) {
		    e.printStackTrace();
		} catch (IOException e) {
		    e.printStackTrace();
		} 
	}
}

Much help needed. Am just a beginner in java role. Thank you

Hi kelvin, welcome to the Ranch!

I don't know how to split it either, because you didn't say what your requirements are. Do you want to write each line into a separate file? Or what? You can't get started on programming if you don't have specific requirements.

Hi,

Yup so in retrieveFile.txt which have 2 big chunk of text i want it split into 2 text file

retrieveFile original text:
<MESSAGE_ID>20160104171116001</MESSAGE_ID>
<MESSAGE_ID>20160104140060012</MESSAGE_ID>

1.retrieveFile1.txt will contain this.
<MESSAGE_ID>20160104171116001</MESSAGE_ID>

2. retrieveFile1.txt will contain this
<MESSAGE_ID>20160104140060012</MESSAGE_ID>

So i want to like save each line of text into new files is it possible?

[Paul Clapham]

Of course it's possible. You have a loop which reads through each line of the input file. So for each line here's what you need to do:

1. Open a new output file with a suitably numbered name. (You have code to do that, just in the wrong place.)

2. Write the line to that file.

3. Close that file.

can i use count? is my count statement wrong?

If i put my writer.close inside

int count =1;
		    bufferedWriter = new BufferedWriter(new FileWriter("D:/randomTesting/newFile" + count + ".txt"));
		    String s = "";
                    while ((s = bufferedReader.readLine()) != null) {
		        bufferedWriter.write(s);
		        count++;
		        // write a new line
		        bufferedWriter.newLine();
		        System.out.println(s);
		        System.out.println(count);
		        bufferedWriter.close(); //only print 1 line then error of stream closed.
		    }

Another question sometimes XML have those whitespaces.

XML file.
<?xml version="1.0" encoding="UTF-8"?>
<PERMIT>
<PERMIT_HEADER>

how do i trim it so i when i do the splitting it wont appear as

1. <?xml version="1.0" encoding="UTF-8"?> - 1 text file
2. <PERMIT> - 1 text file
3. <PERMIT_HEADER> - 1 text file

Many thanks.
