in reply to Creating a hash out of multiple XML attributes in an elment

I think you want something like this:

my $key2value; my $t= XML::Twig->new( twig_handlers => { 'settings' => sub { file( +@_, $key2value); } } ) ->parsefile( 'sample.xml'); sub file{ my($t, $settings, $key2value)=@_; $key2value->{$settings->att( 'key')}= $settings->att( 'value'); }

    Yep. This is going to be a stupid question but how do i retrieve/print the value for, say, key "a"?

      mirod used a key called "key", if you want a key called "a", maybe you should replace "key" with "a" or something like that, I haven't read perlintro so I'm not sure

      $key2value is a hash reference, you retrieve the value for a this way: $key2value->{a}

      see perldata for more info.

        I had tried that at first and it does print the value, but it also prints: Use of uninitialized value $key2value{"a"} in concatenation (.) or string for each "settings" element in the xml.
