in reply to getting required format output from a xml file

Here is a solution using XML::Twig. Please feel free to improve on it as I'm new to XML::Twig ...
use XML::Twig; my $twig= new XML::Twig( start_tag_handlers => { 'level' => \&start_level }, twig_handlers => { 'level' => \&end_level }, ); $twig->parsefile($file); my @levels; sub start_level { push @levels, $_[1]->{att}{label}; print join ('.', @levels), "\n" if @levels == 3 } sub end_level { pop @levels; }
