Greetings Perl Monkers

I've been parsing some XML files using Perl and XML::Twig. I've got the bulk working but I need to parse a final, separate file just extracting out one bit of data. I can to it with xmllint on the command line using - xmllint --format portletEntities.xml --xpath '//*[@name="FilterName"]/*/text()' | sort | uniq

I'd like to get this to work in the Perl code so the values I pull from this search with the other data, in the example below I want "Name_of_filter". Using xmllint with //*[@name="FilterName"]the surrounding data looks like

There 72 entries in raw, 56 unique. In Perl I'm trying this

130 sub parsepages {
131     my $filename = "portlentEntities.xml";
132 
133     my $p = XML::Twig->new(
134     twig_handlers => {
135         '//*[@name="FilterName"]/*/text()' => sub {$_->print}
136         },
137     );
138 
139     $p->parsefile($filename);
140 }
