The code i am using is

#!/usr/bin/perl 
use strict;
use XML::XPath;
use XML::XPath::XMLParser;
use XML::XPath::Node::Element;
use XML::XPath::NodeSet;
my $file = "nci.xml";
my $xp = XML::XPath-> new(filename => $file);
open(info,"+>$file.txt");
foreach my $concept ($xp->findnodes('/NCI_PID_XML/Ontology/LabelType')) {

my $parentid = $concept->getAttribute('id');
my $type = $concept->getAttribute('name');
my $LabelValue = $concept->findnodes('LabelValueList');
my $id =  $LabelValue->getAttribute('id');
my $name =  $LabelValue->getAttribute('name');
my $goid =  $LabelValue->getAttribute('GO');

print info "$parentid\t";
print info "$type\t";
print info "id\t";
print info "name\t";
print info "$goid\n";
}

but it is giving me error
Can't locate object method "getAttribute" via package "XML::XPath::NodeSet" at try1.pl line 15.
