Description:

my $string = "first-item \"second item\" third-item"; my @items = split /???/, $string; my $i = 0; print ++$i, ": $_\n" for @items; # Would print: # 1: first-item # 2: "second item" # 3: third-item

use Text::ParseWords

This doesn't handle all the subtle things (backslashes, single-quotes, etc) that Text::ParseWords does, but it works for the simple cases, and produces your expected output exactly (quotes intact): my @items = ($string =~ /(".*?"|\S+)/g);

Late entry: how about something like this:

my $string = 'first-item "second item" ' . 'third-item "fourth item"'; my %items; push @{$items{ $1 =~ /"/ ? 'quoted' : 'unquoted' }}, $1 while $string =~ /(".*?"|\S+)/g; print 'Quoted: ', join(', ', @{$items{'quoted'}}), "\n"; print 'Unquoted: ', join(', ', @{$items{'unquoted'}}), "\n";
