Thanks for your quick reply, sorry for lack of information. I have added the full code below. I am trying to get the values of author into an array. Unfortuantely  my @array = map{$_->textContent} $authors->findnodes('./authors/author'); does not do this. Hopefuly this makes more sense 

 use CGI qw(-utf-8 :all *table);
use LWP::Simple qw(get);
use URI;
use XML::LibXML;
use Data::Dumper;
use utf8;
binmode(STDOUT, ":encoding(utf-8)");

my $parser = XML::LibXML->new();

$author = param('query');
$maxHits = param('maxHits');

my $url = URI->new("http://www.dblp.org/search/api/?");
my($q,$h,$c,$f,$format) = ($author,$maxHits,"4","0","xml");
$url->query_form(
'q' => $q,
'h' => $h,
'c' => $c,
'f' => $f,
'format' => $format,
);




print header(-charset=>'utf-8'), "\n",
    start_html({-title=>'DBLP Search',
        -author=>'<>'}), "\n";


if (param('submit')) {

    my $xml= get($url);
    my $doc = $parser->parse_string( $xml);
    
    print h1("Authors"), "\n";
    
    foreach my $authors ($doc->findnodes('/result/hits/hit/info'))
    {
        print $_->textContent, "\n" for $authors->findnodes('./authors
+/author');
        my @array = map{$_->textContent} $authors->findnodes('./author
+s/author');
    }
}

print h1("DBLP Query"), "\n";
print start_form({-method=>"POST"
    -action=>"http://cgi.csc.liv.ac.uk/cgi-bin/cgiwrap/u6ed/stat.pl"})
+;
print label("query: ");
print textfield({-name=>'query',
        -size=>200}), "\n";
print label("maxHits: ");
print textfield({-name=>'maxHits',
        -size=>200}), "\n";
print br(), "\n";
print submit({-name=>'submit',
        -value=>'Submit'}), "\n";
print end_form, end_html
