Here is code I'm using...no errors, but does not return anything. 
#!/usr/bin/perl

use strict;
use warnings;

use XML::LibXML;

my $filename = "aos_list.xml";

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

# tried different Xpath - still returns nothing
for my $sample ($xmldoc->findnodes('/GfmDocument/GFMIEDM35/OBJ_ITEM_OO
+_TBL/OBJ_ITEM')) {
    for my $property ($sample->findnodes('./*')) {
        print $property->nodeName(), ": ", $property->textContent(), "
+\n";
    }
    print "\n";
}
