Perl: Split string by everything but whitespaces

I want to split a string by everything but whitespaces.

Example:

Assume that I have a string: 

"The    quick  brown fox    jumps over   the lazy dog"

I want to split it and get the following list of space-strings:

["    ", "  ", " ", "    ", " ", "   ", " ", " "]

Can you please show me how to do it?

Thanks!

why not just look for the spaces instead of splitting by non-space characters?

You can use \S to split by here which means match any non-white space character.

my @list = split /\S+/, $string;

Or better yet, just match your whitespace instead of having to split.

my @list = $string =~ /\s+/g;

\S splits on any non-whitespace. However, if you want to include tabs and newlines, then you should use (single character space). More than likely what you want is the \S as hwnd has provided.

my $string = q{The    quick  brown fox    jumps over   the lazy dog};
my @values = split /[^ ]+/, $string;
