Bad Variable-naming IMHO. $results has nothing to do with your expected
results, by convention this is called $root because it's the
startingpoint for all further actions (think of it as:
the-whole-xml-document).

my $seq_name = $results-> field();

<Quote from the docs:> 
field ($optional_condition)
    Same method as "first_child_text" with a different name
</Quote from the docs:> 

So, field() will give you the text of $root's first-child, which happens
 to be the <name> tag.

TIMTOWTDI, as always.

One Way:
my $first_process = $twig-> first_elt('processName');
print $_-> text, "\n" for
    ( $first_process, $first_process-> next_sibling );

Another Way:
my @processes = $root-> children('ProcessNames');
for ( @processes ) {
    print $_-> text, "\n" for $_->children;
}

Yet Another Way:
my @names = $root-> descendants('processName');
print $_-> text, "\n" for @names;
