( #3333=superdoc: print w/replies, xml ) Need Help??
I like to use this syntax to capture from regular expresions.
if (my ($a, $b) = ("$key$val" =~ /(..)(...)/)) { $hash2{$a} = $b; }
#!/usr/bin/perl use Test::More "no_plan"; use Devel::Size "total_size"; my $key = "aa"; my $val = "a00"; my %hash1; my %hash2; while (length($key) == 2) { $hash1{$key} = $val; if (my ($a, $b) = ("$key$val" =~ /(..)(...)/)) { $hash2{$a} = $b; } ++$key; ++$val; } is(keys(%hash1), keys(%hash2), "same number of keys"); is_deeply(\%hash1, \%hash2, "is_deeply same"); is(total_size(\%hash1), total_size(\%hash2)); __END__ ok 1 - same number of keys ok 2 - is_deeply same ok 3

A picture is worth a thousand words, but takes 200K.

    [GotToBTru]: you are correct, choroba, but of course there is no point in doing one without the other
    [GotToBTru]: un less you're working on write-only memory
    [1nickt]: my $x = $aohoaoh->[0]->{' foo'}->[0]->{'bar' }; should work
    [thepkd]: not indexing
    [thepkd]: getting data out of the ds
    [choroba]: it depends. Give more details, please
    [thepkd]: i used a series of {}'s but it dont work
    [choroba]: You need square brackets for arrays
    [GotToBTru]: you can certainly construct a single expression to access any part of the data structure, without using temp variables. but you might make it easier on yourself and any other poor soul who has to understand your code if you do
