Though we have arrived at very similar solutions, I think yours fails to pick up multiple values for the last key:
use strict; use warnings; use Data::Dumper; my $data="key1=value1 key2=value2 value3 key3=value4 value5 value6 key +4=value7 key5=value8 key6=value9 value10"; # Albannach version my %hash; while ($data =~ /(\w+=)((\w+( |$)+)+)/g) { $hash{$1} = $2; } print Dumper \%hash; # gumpu version: my %foo; while ($data =~ m/(\S+)=(\S+($|([^=]+\s+)+))/g) { $foo{$1}=$2; } print Dumper \%foo;
Produces:
$VAR1 = { 'key4=' => 'value7 ', 'key5=' => 'value8 ', 'key1=' => 'value1 ', 'key6=' => 'value9 value10', 'key2=' => 'value2 value3 ', 'key3=' => 'value4 value5 value6 ' }; $VAR1 = { 'key1' => 'value1 ', 'key2' => 'value2 value3 ', 'key3' => 'value4 value5 value6 ', 'key4' => 'value7 ', 'key5' => 'value8 ', 'key6' => 'value9 ' };

Update: The = in the key? You are right of course - silly me! Thanks gumpu!

    It does not pick up the last value for the last key, should have tested it better. I also think that your version is more readable. Though I would leave out the = from the key.

    $hash{$1} = $2 while ($data =~ /(\w+)=((\w+( |$)+)+)/g);

    Have Fun
