Help w/ splitting plain text file with regexp

If the number of countries is small (and the number of files as well) you could use Notepad++ and a regular expression to order your information and then store it manually in files per country.

In either the normal Ctrl+F/R or advanced Ctrl+R find and replace dialog, enter the following expressions:

Find field:
^(.*)-([^\-]+)$

Replace field:
\2-\1

This will reorder the contents of each line into "Country"-"name". The name itself may even contain - characters: only the last - is seen as separator before the country name.

When you have done this, you could sort all lines alphabetically: the information will be grouped by country.

Then you could manually split the list(s) into documents per country.

You can remove the country name and - character by using column block selection.

Select all lines and move the cursor to the - character on the first or last line.
Keep the Shift button down while also pressing Alt and Cursor Right.
Press Delete to remove the select column, leaving only the names.

Since you have to split files, I don't think N++ is the right tool. I'd use something like AWK.
What you have to do is:
1) Look for the "-" charachter in every line, using the match($0, /-/) function. Its position in automatically saved into the RSTART variable
2) Read the rest of the line, starting from there, and save that into a string: that's the country name
3) Read from the beginning to the position previous to "-", and save that into another string: that's the person's name
4) Print the person's name into a file that has the country name.

Here it is:
{
    if (match($0, /-/)) {
        countryname = substr($0, RSTART + 1);
        person_name = substr($0, 1, RSTART - 1);
        print person_name >> countryname".txt";
    }
}

Save this code into a file called countryname.awk and run the command "awk -f countryname.awk listfile", where listfile is, well,  the name of your list file :-)
AWK comes with many Linux distributions, and is also available for Windows.

Hope this helps you!

I couldn't quite wrap my head around AWK, so i ended up doing it in C#. Thanks for the help though!
