Hi ,
=A0
using split ,I would like to split on space character. Dont want to use cha=
racter classes.
my $string=3D"108 ambulance 100\nfireengine141jack";
=A0
my [at] array =3D split /' '/,$string;=A0
=A0
foreach my $value ( [at] array){
print "$value \n";
}
=A0
Result : its splitting on new line character.instead of space character.
=A0
Can some one clarify ?
=A0
for the same if the string is enclosed in single quotes ,splitting is not h=
appening on the given string.
=A0

You need =ABmy [at] array =3D split / /, $string;=BB instead. =ABsplit ' ', $st=
ring;=BB is
more magical.

It's clarified in http://perldoc.perl.org/functions/split.html

my [at] array = split / /, $string;

Can you clarify what you mean by that?

From the doc: perldoc -f split

As a special case, specifying a PATTERN of space (' ') will
split on white space just as "split" with no arguments does.
Thus, "split(' ')" can be used to emulate awk's default ...

So, /' '/ in your regex causes a pattern match on a
literal ' '. When the search fails, the entire $string is
returned:
=A0

> print "$value \n";}

No, there's no split on a newline. You'd have to specify
/\n/ for that to happen. In your case, the whole string
is returned since the pattern match fails. This would've
been clear if your code had been:

foreach my $value { [at] value) { print "=3D$value=3D\n"; }

which would've printed:
=3D108 ambulance 100
fireengine141jack=3D

No, single quotes don't impact the split but only
whether interpolation occurs inside the string.
