Split Decision

Happy New Year All - I hope noone over-indulged with the Mead! This is one of my quick silly questions so enjoy! I'm trying to use split on \n with, so far, no success. Can this be done? (chomp is of no use as the records in question have \n embedded in many places. The suggestions that I've had so far are the things that I have tried (with nada success!)

my @lines    = () ;
#
($msg) = @ARGV ;
#
@lines = split /\n/,$msg ;
#
foreach (@lines) {
   print "\n$_\n" ;
}
#
print "\n" ;

I've tried this with & without the double quotes round the \n in the split statement and the best I get now - and the word useless springs to mind -is one field, xnynz. So the split hasn't completely worked it's removed the \'s from the field only! Sorry guys but NONE of your suggestions work! Have any of you actually tried this? Cheers, Ronnie

Try "\n" instead. Examine what is said, not who speaks. Silence betokens consent. Love the truth but pardon error.	[reply] [d/l]

`'\n'` will also work: `#!/usr/bin/perl my $string = "Bla\nBlo\nBloe"; print join("\|", split('\n', $string));` [download] This works, and the reason becomes clear when you run it through B::Deparse: `$ perl -MO=Deparse split.pl my $string = "Bla\nBlo\nBloe"; print join('\|', split(/\n/, $string, 0)); split.pl syntax OK` [download] Arjen	[reply] [d/l] [select]

You live and learn :) What a stupid special exception! Examine what is said, not who speaks. Silence betokens consent. Love the truth but pardon error.	[reply] [d/l]

Beats me, there should be no problem splitting on a '\n': `my $test = "this\nis\na\ntest"; + my @foo = split /\n/, $test; + print +join '*', @foo;` [download] I would guess that infact what you think is a '\n' is something else. /J\	[reply] [d/l]

Change your string to 'x"\n"y"\n"z' and you'll be enlightened. Being right, does not endow the right to be rude; politeness costs nothing. Being unknowing, is not the same as being stupid. Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence. Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.	[reply]

Just because no one has said it yet ... The reason your code doesn't work is that you're splitting on "double-quote newline double-quote" rather than just splitting on "newline" as you intend. duff	[reply]
