Fail to split downloaded txt file

Postby Morgrom » Thu Mar 03, 2011 2:37 pm

I have a String that I try to split. The following code works
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. lsSagor = "some text\n Some more text\n More text~Text again\n Text\n text~Some text ..."
  2.  
  3. final String[] laList = lsSagor.split("~");
  4.  
  5. String[] laSaga = laList[0].split("\n");
  6.  
Parsed in 0.011 seconds, using GeSHi 1.0.8.4

Gives:
laSaga[0] => some text
laSaga[1] => some more text
laSaga[2] => More text

But if I download the textfile, it fails to split and gives:
laSaga[0] => "some text\n Some more text\n More text"
So it seems the first split works, but not the second.

There is the code I use to download the file
Syntax: [ Download ] [ Hide ]
Using java Syntax Highlighting
  1. String lsSagor = getFileFromUrl(BASEURL+"/sagor.txt");

Make sure that the text file you are downloading uses Unix-based end of line character format.

The desktop is Linux, the server is Linux and I actually write "\n" in the textfile. It seems that \n is a bad character to use.

I changed the code to use # instead of \n and than replace # with \n for output:

So the textfile looks like this "some text# more text# and more text ~some text ..."
