I'm parsing a XML file where the data section has a number of nodes and then multiple subnodes. When I try to print out the subnodes, I get:

XML::LibXML::Element=SCALAR(0x880714) for all the details.

Here's the code, problem is in the 3rd foreach block...

#!/usr/bin/perl -w

use strict;
use XML::LibXML;

@ARGV == 1 or die("Usage: $0 data file\n");

my $parser = XML::LibXML->new(XML_LIBXML_RECOVER => 2);
   $parser->recover_silently(1);

my $data_file = $ARGV[0];
my $doc = $parser->parse_file( $data_file );

foreach ('root_detail_risklevel_1', 'root_detail_risklevel_2', 'root_d
+etail_risklevel_3', 'root_detail_risklevel_4') {
            
    my($risk_level) = $_;
    print $risk_level . "\n";
    
    foreach ($doc->findnodes("//".$_."/data")) {
        
        my($risk) = $_->findnodes('./risk');
        my($check) = $_->findnodes('./checkname');
        my($desc) = $_->findnodes('./description');
        my($version) = $_->findnodes('./version');
        my($cve) = $_->findnodes('./cve');
        my($cce) = $_->findnodes('./cce');
        my($summary) = $_->findnodes('./summary');
        my($overview) = $_->findnodes('./overview');
        my($fix) = $_->findnodes('./fix');
        
        foreach ($_->findnodes('./details')) {
            my($detail) = $_->findnodes('./vulnDetail');
            print $detail . "\n";
        }
    }
}

Syntax error in the innermost foreach block?

Help is much appreciated!
