Answer 1

You can iterate over using

  for my $node (@$paraelements)  { ..... }

A more complete example

  use HTML::TreeBuilder::XPath;
  my $tree= HTML::TreeBuilder::XPath->new;
  $tree->parse_file( "mypage.html");
  my $paraelements= $tree->findnodes( '//p') ;

  for my $node (@$paraelements)  {
      say $node->as_HTML() ;
  }

It returns a reference to a list (ARRAYREF). To get back the list, put a @ before the variable to tell Perl to treat that as the [location/memory address] of the list just as JIT's sample code
